Ranking The Best Marine Oil On The Market

Quicksilver 4-Stroke EFI Marine Oil

Red Line 40605 2-Stroke Race Oil

Lucas Oil Semi-Synthetic 2-Cycle Oil

If you want your boat’s engine to enjoy a long and productive life, you need to treat it with nothing less than the best marine oil that you can buy. Since your boat’s engine is the most important part of the vessel (aside from the hull, of course), it needs to be well taken care of and meticulously maintained. You can cut corners in a number of ways, but when it comes to your engine, don’t even think about it.

That means you should use a dedicated marine oil, and nothing else. As tempting as it might be to use the same oil that you’d use for you car, think again. Boat engines have very different oil specifications.

For a start, a marine engine requires an oil that can protect it from the effects of water, resisting rust and corrosion, and all the other problems that are caused by water. But that’s not all.

Marine engines operate differently too. They run harder and faster, often in the highest rev ranges. After that, they’re usually left alone for long stretches, unlike a car that’s used regularly. Dealing with these two extremes can take its toll on a boat engine, and that’s why you need specific marine products to keep your boat ship shape . And that goes for the engine too.

There are lots of different oils on the market, from two-stroke to four-stroke, with different weights and properties for a wide range of applications. So, to make life a little easier, we’ve drawn up a top list of the best boat oil products out there, with a buying guide to make sure that you buy the best oil for your engine. Here’s all you need to know.

Quicksilver’s all-inclusive 4-stroke oil and changing kit is a great choice for easy marine oil changes. It’s an inexpensive kit that’s simple to use, convenient in nature, and perfect for all marine 4-stroke engines However it has been made with Mercury Mariner engines in mind. It’s available in three different configurations, to suit different engine sizes. These sizes include engines from 25 hp to 30 hp, engines between 40 hp and 60 hp, and for engines between 75 hp and 115 hp.

The actual oil is a 25W-40 engine oil that has been formulated with a number of additives to provide extra engine protection. Some of these additives include Quicksilver’s Flagship Protection formula, which features anti-wear properties that increases crankshaft protection by up to 33%.

Each kit comes with a variety of essential oil changing tools, including a bottle of marine oil, a new oil filter, a drain plug seal, a handy drip tray, and clear and concise instructions.

If you’re looking for an affordable all-inclusive oil changing kit from a reputable brand, then this Quicksilver 4-Stroke EFI Marine Oil kit is worth the money. Make sure that you purchase the correct kit for your engine type though, and read the customer reviews to ensure that the supplied oil filter or fuel filter is compatible with your motor.

Oil Type: 4-stroke Oil Weight: 25W-40 Certification: FC-W Bottle Size: 1 liter per kit (unless stated otherwise)

Next, we have another boat oil designed specifically for two-stroke motors. This is the 40605 race oil blend from Red Line. It’s a versatile oil that’s ideally suited to marine, motorcycle, ATV, and other powersports activities. This is a high-performance oil, and while it’s geared towards racing applications, it’s perfect for high-revving two-stroke marine motors.

This formula is a touch on the expensive side, but if you want the best performance out of your engine, with smooth running and top tier protection, this is worth the extra. It has been specially formulated for high-temperature stability, which is proven to produce gains and improvements of between 3 and 5 percent when compared with other oils.

In terms of protection, this marine oil can prevent the build-up of carbon around particularly susceptible areas of your engine, such as around the combustion chambers, piston rings, and exhaust ports. The result is an engine that can perform better, run smoother, and will last longer than others being serviced with other oils.

It burns clean, reduces smoking, and will help preserve your engine—and some of its perishables too, such as the spark plug and gaskets.

But performance like this isn’t cheap, and there’s no escaping the fact that this oil has a higher price tag than others. This is a great investment if you really want performance that sits at the business end of the spectrum. However, it might be overkill for the average boater.

Oil Type: 2-stroke Suitability: Oil injection and premix Certification: TC-W3 Bottle Size: 1 U.S gallon (3.78 liters)

Sierra 25W40 Boat Oil

If you’re looking for an inexpensive marine oil that’s designed and engineered to improve the performance and prolong the life of an inboard engine with outdrive propulsion, then this formula from Sierra offers excellent value for money.

This reliable 4-stroke engine oil has a viscosity of 25W-40, and it has been specially formulated for inboard and stern drive engines. Don’t make the mistake of confusing this with outdrive lubricant, because it’s not the right tool for the job. This marine oil is excellent for a range of other applications though.

Despite the fact that this is a cheaper product, it does have a number of premium features. The most talked about one (and arguably the biggest strength of this oil) is that it runs clean even in cold temperatures—an area that many other oils have been known to fail in.

It can also handle high horsepower engines and all of the wear and tear that inevitably goes with them, and it can also handle itself well in a marine environment, which can be undoing of some cheaper priced oils.

Again, it’s a cheaper oil, but it has all of the necessary certifications, including the most important NMMA (National Marine Manufacturers Association) FC-W one . It ticks all the right boxes, and won’t leave your wallet empty either. You even get quite a lot of it for your money too!

Oil Type: 4-stroke Oil Weight: 25W-40 Certification: FC-W Bottle Size: 5 U.S Quarts (4.7 liters)

Mercury 4-Stroke Marine Engine Oil

When it comes to marine engines Mercury know what they’re talking about. Mercury is one of the leading names in the industry, manufacturing quality marine engines. Whether you’re in the market for an outboard motor or an inboard engine, they’re a go-to brand. So it should come as no surprise that they manufacture their own line of engine oils and lubricants too.

This particular lubricant is a synthetic oil that has been developed specifically for four-stroke engines. It has a combination of synthetic blends and additives to provide the best lubrication and protection to gasoline engines. It successfully offers superior corrosions protection when compared with other boat engine oil products, which has made it one of the most highly recommended OEM marine oils in the business.

This is a 25W-40 synthetic blend oil designed for use in a wide range of marine applications, including outboard, stern drive, and inboard engines. It’s available in 1 gallon bottle sizes, which makes it ideal for your next boat engine oil change.

It’s ideally suited for high revving engines, but it also works very well for lower horsepower motors too. Though it’s a touch more expensive than other products on the market, this oil will improve your engine life and keep your maintenance costs down. Plus, despite the fact that it is often considered a premium product, it’s not actually that expensive either.

Oil Type: 4-stroke Oil Weight: 25W-40 Certification: FC-W Bottle Size: 1 U.S gallon (3.78 liters)

For two-stroke marine oils, you should start your search by checking out what Lucas Oil has to offer. Lucas is one of the biggest names in the lubrication game. If it has an engine, you can bet that Lucas has an oil for it. For the best marine oil for 2-stroke engines, we’d recommend the Lucas Oil Semi-Synthetic 2-Cycle Oil for consideration.

This oil has a unique blend that helps transform it into an environmentally conscious lubricant. Or at least as environmentally-conscious as an oil can be . It has a smokeless nature, which allows it to burn much cleaner than other oils, and it also boats a low ash production. Since it’s greener than other products, it makes it a far superior choice for marine applications.

It’s not just environmentally-sound either. It also offers excellent performance and increased protection, particularly for air-cooled engines. The formula is ideal for preventing carbon deposits from building up around piston rings, and inside your combustion chambers. It prevents rust, corrosion, and promises to keep your engine running better, for longer.

Naturally, this oil conforms to all regulations. It’s ISO GD and JASO FC approved, and meets and exceeds both API TC and FD standards. It’s a versatile product that can be used in two-stroke engines that are either direct oil injection or where premixing is necessary.

What’s more, this oil can actually be used for your two-stroke motorcycle too, should you have one in the garage. This makes it quite a versatile purchase. Take note though: it’s not the best choice for mixing into your weed whacker or other outdoor power tools.

The Best Marine Oil: A Buying Guide

While all engines are similar in nature, they have very different needs. Giant diesel engines have a different oil specification than a small outboard engine would, and what’s good for a fishing boat probably won’t be ideal for a high-performance power boat. The moral of the story is this: there’s no one-size fits all boat oil—not if you want decent results anyway.

Understanding how your boat engine works and what it has been designed for is key to finding the best oil for the job. While boat motors share similar DNA to engines found on land-going vehicles, such as their need for lubrication, and protection, there are some key differences. For example, marine vehicles are often in contact with water, salt, and other potentially troublesome materials, and it’s because of this that they often need specialized protection from their motor oils.

But before we get to that part, let’s look at some of the most important things to look out for when buying new oil for you boat.

Two-Stroke Or Four?

Marine gasoline engines come in two distinct flavors: two-stroke, and four-stroke. The different engine types have different pros and cons , but we’re not here to go into detail about that. When it come to lubrication, they have major differences.

Two-stroke engines don’t have a separate lubrication system. The oil and fuel are mixed, consumed, and burned together. The oil can be injected from a separate reservoir directly into the combustion chamber, or it can be premixed in the fuel tank. This lubricated the engine as it’s used.

Four-stroke engines have a similar lubrication system that you’d find on your car. It’s a separate, self-contained system that requires you to add oil to an oil tank, which is then routed to where it needs to go. The oil isn’t spent and consumed along with the fuel.

You should be aware of what kind of engine you have. Two-strokes are generally quite noisy and exhaust noticeable blue smoke. Four-strokes are quieter and appear to burn cleaner. At this point, if you’re still not sure what type of engine you have, you probably shouldn’t be changing your own oil.

Viscosity Level

For the best results, always follow your manufacturer guidelines. Four-stroke oil will come with a viscosity level, or oil weight, printed on the bottle. It’s always recommended that you follow your manufacturer’s advice. So, if they recommend an oil with a weight of 25W-40, then you should use an oil with the same specification.

But what does that number mean?

In short, viscosity is a fluid’s resistance to flow; in this case, the viscosity is rated at two different temperatures, since oil thickens as it cools and thins as it heats. The first number is the viscosity rating that an oil has a zero degrees Fahrenheit. It’s designated with a “W” which stands for “Winter.” The second number is the oil’s viscosity at a much higher temperature, at 212 degrees Fahrenheit, to be precise. As oil gets thinner, it’s not as useful. So, a higher second number is generally better.

That’s a very simple explanation though. For the best results, we recommend that you follow the oil requirements that your manufacturer suggests.

Apart from viscosity and lubrication, there are a number of other useful features that motor oil can do. The most important one is protecting your components from damage, and extending an engine’s lifespan. Marine engines are particularly vulnerable to rust and corrosion thanks to the wet and humid conditions that they have to operate in, but with the right oil and the right blend of additives, they can be kept at bay. Almost all marine oils will have some kind of rust-protection requirement.

Look for oils that have additives and inhibitors that have been specifically engineered to stave off rust, prevent carbon build-ups, and stop corrosion in its tracks. Rust, corrosion, and excess carbon can lead to catastrophic engine failures.

Lastly, there’s the price. There are many boaters out there who will preach that oil is oil, and the differences between one brand and another are negligible. They would be right, to a degree. Any oil is better than no oil—we can all agree on that. However, those lubricants that have been specially engineered to inhibit engine wear are definitely worth paying more for.

More expensive, advanced oils will cost more, but they should extend times between maintenance. Whether you pay more for longer maintenance intervals, or pay less for oil but have to change it more often, that’s up to you. Just make sure you oil those engines!

Choosing the Right Fuel and Oil for Your Marine Engine

Using the correct marine fuel and oil in any boat's engine —outboard, sterndrive or inboard—will ensure many seasons of reliable performance. For guidance on fuel and oil requirements for your marine engine, turn first to the owner’s manual (if you don’t have that manual it may be available online or you can order a copy from a dealer ).

Following the fuel and oil specifications in the manual will ensure not only that your motor maintains reliable performance, but also that you are in compliance with the manufacturer’s warranty requirements.

Explore Different Types of Marine Engines

What Type of Gas Should I Use in My Boat?

All current outboard, sterndrive and inboard gasoline engines are designed to operate safely on fuel with no more than 10 percent ethanol (known as E10), and under no circumstance should fuel with more than 10 percent ethanol (such as E15 or E85) be used in a marine engine. Its use will void the warranty.

The fuel system components of the boat and engine are not designed to tolerate the corrosive effects of an ethanol blend higher than 10 percent. There are also many older marine engines on the water, especially in freshwater areas, that were manufactured before any amount of ethanol was common in motor fuel and are thus often incompatible with ethanol fuels unless the system is updated. Pay attention to the fuel pump labels. E15 is becoming more prevalent across the country but is not always obviously labelled.

When possible its best to avoid ethanol all together when fueling up a boat. Ethanol attracts water and can absorb moisture from the marine environment through the fuel tank vent system, and it’s possible for that water to settle out of the fuel (phase separation) on the bottom of the tank, which could cause the engine to not operate or be damaged.

The owner’s manual may also specify a minimum fuel octane rating. Some high-performance engines may require a higher octane rating than “regular” 87 octane. A 10-micron water-separating fuel filter between the fuel tank and the engine will keep water and contaminants out of the engine.

• Carry a spare filter element on board (check with your engine manufacturer for the best size filter).
• Use marine-specific fuel stabilizer at the correct ratio in every tank of fuel to prevent oxidation and phase separation. Modern fuel can begin to deteriorate and oxidize in as little as 15 days. This is more of an issue for older “pre-fuel injection” engines that have a carburetor.

A fuel injection system is closed and under pressure when the engine is not running so fuel is not exposed to air. A carburetor is vented, however, and fuel in the float bowl will begin to oxidize especially quickly if the boat is kept in a hot garage or under a heat-trapping cover, leaving behind gunky deposits that will ruin your weekend. Every engine manufacturer offers a quality fuel stabilizer additive that’s always a good choice for use with boat fuel.

Choosing the Right Marine Oil 

Consult your owner’s manual for the exact oil specification, but in almost every instance the manufacturer will require that oil for four-stroke engines meets the FC-W certification (it will have an FC-W symbol on the label). The FC-W spec adds a rust-protection requirement that does not exist for automotive engine oils, and imposes a higher minimum viscosity level, which means that FC-W oil will not thin out as much as automotive oil of the same viscosity under identical heat and rpm conditions. Follow the owner’s manual maintenance instructions regarding oil and filter changes.

Two-stroke outboards require oil that meets the TC-W standard , which indicates a marine oil designed for a two-stroke engine. Again, consult the owner’s manual for specific two-stroke oil requirements.

What Motor Oil is Right for Your Boat or Personal Watercraft Engine?

Dedicated marine motor oil is vital to marine engine protection.

Shop the article

Rust and Corrosion

Protection against rust and corrosion is the primary reason to use marine motor oil in your boat or personal watercraft engine. Despite what most people might naturally assume, motor oils have no natural ability to protect against rust or corrosion . Instead, special rust and corrosion inhibitors must be added to the formulation to provide the required protection. Most oils simply don’t contain the correct additives in the correct concentration.

During engine operation, a layer of oil coats engine parts and the crankcase walls. The lubricant film protects against rust and corrosion as long as it remains in place. However, after you shut down the motor for the day, gravity draws the oil back down into the oil sump, leaving components unprotected.

The longer the engine sits, the more likely rust and corrosion will form. Since cars and trucks are typically driven daily, rust and corrosion largely isn’t a concern. As such, most automotive motor oils don’t contain sufficient rust and corrosion inhibitors for marine engines.

Once rust begins to form, it doesn’t stop. Rust can slowly spread to the crankshaft journals, cylinder wall, piston rings and other areas. Rust acts like sandpaper and scours metal surfaces until engine failure results. Rust can also prevent the piston rings from forming a good seal against the cylinder wall, which reduces compression and leads to power loss.

  It is vital to use a motor oil formulated with anti-rust and anti-corrosion additives in your marine engine.

Aluminum parts may not rust, but they can corrode, especially in marine motors constantly exposed to humid air. All cylinders aren’t completely sealed when the engine shuts down, allowing damp air to infiltrate the combustion chamber and cause aluminum pistons to corrode. Corrosion on the piston crown invites conditions that can lead to pre-ignition detonation, a phenomenon where the fuel/air mixture ignites sporadically and potentially causes catastrophic engine failure.

Marine motor oils are specifically formulated with anti-rust and anti-corrosion additives to protect your boat’s engine. These additives form a resilient protective layer that clings to engine parts for maximum protection. Make sure you choose a dedicated marine motor oil to prevent rust.

Fuel Dilution

Fuel dilution is another problem many boat owners don’t think about. Fuel leaking into the oil sump is especially problematic in marine engines compared to other engines.

Outboard motors and personal watercraft typically use lake or river water for cooling. When started, the engine draws water into the cooling system and circulates it throughout. Marine engines generally take longer to warm up than engines with a closed cooling system that uses a radiator and coolant.

A cold engine can prevent the rings from sealing completely. More clearance between the ring and cylinder wall allows fuel to leak into the oil sump, diluting the oil and reducing its ability to protect against wear. Be sure to choose a dedicated marine motor oil to keep the cold engine lubricated and minimize fuel dilution.

  AMSOIL maximizes your marine engine’s performance and life, so you can stay on the water longer!

Increased Stress

Adding to the challenge, marine motors are constantly under load, which physically damages the structure of conventional motor oil, reducing the oil’s ability to guard against mechanical wear .

Consider that a typical marine motor propelling a boat at 30 mph operates around 5,000 rpm. Compare that to an automotive engine, which runs about 2,000 rpm at 60 mph. Unlike automotive engines, which shift gears to reduce engine speed and rpm, boat motors only run in forward or reverse, putting more stress on the oil’s ability to both cool and lubricate the engine under load.

That increased stress requires a robust oil formulated to withstand the shearing conditions inside the engine. An improperly formulated oil loses viscosity, becoming thinner under stress and heat, which prevents the oil from forming a durable lubricating film that protects against wear on moving parts. Always choose a dedicated marine motor oil designed for the increased engine stress found in marine environments.

TC-W3 Oil – What Is It and Why It’s Needed

To understand what TC-W3 oil is, you have to take a look at all the components in its name and understand them. Basically, TC is short for two-cycle, meaning that the oil is a two-cycle one. The W comes from the fact that the oil is water-cooled, whereas the 3 means that it is the 3 rd formulation of oil for a two-cycle, water-cooled engine.

This oil formula has been made in order to keep outboard engines running strong while reducing the bad impact they have on the environment. Although many people thought the oil-fuel mixture would be forgotten as it’s harmful to nature, some brands came up with the idea to create a formula that protects the environment too. That being said, the TC-W3 oil formula was born.

What Features You Should Consider When Shopping for 2 Stroke Outboard Oils

It’s always important to be well-informed before going shopping because otherwise, you risk ending up with an improper product. After all, you can’t get a 4-stroke oil for your 2-stroke engine. So, no matter if you’re looking for marine battery chargers or even a new motor , you must be properly informed.

So, keep in mind that the best oil will keep your outboard strong and durable.  Here are some features to take into account before you get that new 2 stroke outboard oil.

You will notice that prices vary for 2 stroke outboard oils, depending on how good they are, or where you get them from. Sadly, many of them tend to be overpriced. While in some cases the price is well-deserved, some products tend to raise prices while the product leaves much to be desired. When you look for outboard oil online, the best thing to do is to check the reviews and see if the price is worth it. If the price is too high yet people are complaining about the results, it’s best to avoid that product.

• Synthetic or not?

Even 2 stroke outboard oils come in multiple types, believe it or not. You need to think well about the type of oil your outboard will need, especially if you want to maintain it and keep it working for a long time, saving on reparation bills.

One of the types is synthetic two-stroke oil. It has a lot of benefits for 2-stroke outboards because it can provide some extra lubrication and increase combustion. To make things even better, this oil can keep your engine clean. Every part of the outboard will be clean, even the nuts, bolts and piston. This oil can be quite pricey, though.

If you don’t get a synthetic one, there will be more risk for your outboard and you may have to either repair it quite often or look for a new one when it stops operating properly.

• Non-Smoke and Odorless

The last thing you want from your outboard is for it to produce smoke, whether you’re using 2-stroke or 4 stroke outboard motor oil . Smoke is usually caused by a two-stroke oil buildup that settled on the crankshaft area’s bottom. That’s exactly where your engine is situated, and it means the fuel has been burnt on combustion. That will cause a lot of smoke, and a bad smell too, and you want to prevent that.

This is why you must look for an oil that prevents the apparition of smoke. Many products specify this feature in the description, but it’s also best to check the reviews too and ensure it works before you actually buy the oil.

• Versatility

Although 2-stroke outboard oil is meant to only be used for outboards, there are oils that can be used for other motors as well. Having said that, some oils can work for your motorcycle, jet skis and many other units. If you find an oil that is suitable for those units as well, that’s even better.

• Certification

As with everything related to marine equipment , you need something of high-quality. In this case, certification is something to take into account. It’s important to check whether your oil carries either a Jaso FD or an ISO-I-EGD certification. Although you can also settle for a cheaper one with API-TC standards, it’s better to go for something safer.

What Are the Pros of Using 2 Stroke Outboard Oil?

• It Prevents Buildup

Isn’t it annoying when you get carbon buildup in your engine? This will force it to function and could potentially stop the engine from working altogether. You don’t want to spend money on reparations or a replacement, so a good oil will work to prevent buildup. This is what 2-stroke outboard oil can do.

• Helps the Unit Run Smoothly

If you’re tired of the amount of time it takes for your outboard to start, you’ll be happy to know that 2-stroke outboard oil can prevent this from happening. It will help the engine run in a smooth manner, making sure there are no delayed starts and that you experience no performance issues with it.

• It Will Prevent Gas Oxidization

You may be tired of gas oxidizing in the engine, which is why 2-stroke outboard oil might be the right choice for you. Since the oil contains fuel stabilizers, it will make sure there will be no oxidization, so your engine will be in good condition all the time.

Your outboard engine cannot run properly unless you use the right oil – in which case, a 2 stroke outboard oil is a must. Picking one might be difficult though, as there are so many brands and types of oil to choose from. That being said, we hope this guide has helped you, and now you can choose the best 2 stroke outboard oil.

How To Change The Oil In A 4-Stroke Outboard Engine

Advertisement

Oil is the lifeblood of your outboard. Follow these tips when it's time for a transfusion, or at least an oil change.

So, you're basically a DIY sort of boater, and your new four-stroke outboard is not so new anymore. It's past the warranty period, and you're ready to do some maintenance on your own in the hopes of saving some cash. Changing the oil is one of the best things you can do to prolong the life of your outboard, and it's an uncomplicated job that's well within the realms of an enthusiastic owner.

That being said, if your engine is still under warranty, and you're not that mechanically inclined, you might want to consider not doing your own oil changes and leave it up to the dealer, especially if additional work is required. Yes, it will cost more than doing it yourself. But there are some good reasons, especially during the factory warranty period, to simply let the dealer do this work:

• If anything goes wrong with the engine internally, and it has anything to do with lubrication or the lack thereof, you're not even in the equation. All the responsibility lies with the dealer if the engine is still under warranty.
• When it comes time to resell, having all dealer records of each service goes a long way toward a successful sale, and a higher price.

If you're so inclined, however, changing your own oil is not all that complicated, plus there are some benefits outside saving money. You'll learn a little more about your engine and get a closer feel for what makes it tick. Best of all, you get the satisfaction of doing it yourself.

How To Change The Oil Step-by-Step

Technical support.

Degree Of Difficulty: Easy to Moderate

Tools and Materials:

• Remote oil change pump (if needed)
• Screwdriver
• Grease gun with Zerk fitting
• Marine four-stroke oil
• Waste oil container
• Gallon-sized resealable bag
• Marine waterproof grease

Time: 1 hour.

Cost: Around $50 in materials (depending on size of engine.

1. I start by tilting our subject Suzuki 115 four-stroke down to the running position in order to drain all oil effectively. Follow the manufacturer's recommendations for your specific outboard. Warm up the engine (not shown) to ensure that the crankcase oil gets warm and flows easy for more complete draining. (If the boat is not in the water, you'll need to use muffs.)

2. In this engine, I need to remove the lower cowls in order to access the drain screw and oil filter.

3. Remove the drain screw. This one on the starboard side of the exhaust housing is fairly easy to access. Other motors have a drain plug in the aft end of the lower unit.

4. Be ready with a drain pan to catch the oil. In addition, you may want to lay some type of barrier on the ground to protect against spillage. NOTE: Some newer engine models are designed to use only an oil extraction pump (not shown). On these engines, the pump lift tube should reach all the way to the bottom of the crankcase to effectively pull out all the old oil and any debris inside. If your outboard doesn't have this feature, it's preferable to use the drain-plug method in order to ensure complete drainage.

5. Remove the old filter (you may need an oil filter wrench if it was tightened excessively) and reinstall the drain plug if you removed one.

6. Before installing the new filter, lubricate the O-ring seal with fresh oil.

7. Install and hand tighten the new filter.

8. Refill the crankcase with fresh marine four-stroke outboard oil , preferably the manufacturer's brand, using the amount required by the manufacturer. Carefully check the level, making sure that it reaches the full mark on the dipstick. Replace the dipstick, then start the engine and let it idle for 15 to 30 seconds — nothing above idle speed! The idea here is simply to distribute the new oil throughout the crankcase and cylinder head, and to fill the filter.

9. Stop the engine and check the oil level , adding extra if it's below maximum, until it reaches the proper level on the dipstick. Start the engine again, let it idle some, rev it slightly, and shut off again. Check the oil level one last time. After running for several minutes, check the new filter to be sure it's not leaking around the seal.

10. While you're at it, grease all fittings on the outboard with marine waterproof grease. You'll need a grease gun with a Zerk fitting. Check the service manual for all Zerk fitting locations.

10 Tips For Success

• Get a factory service manual for your specific year, make, and model engine. Most sell for less than $50, and it's money well spent. Cheaper aftermarket manuals typically address multiple engines across multiple years, the descriptions and illustrations are not as clear, and some have even been known to publish incorrect information.
• Change the filter at the same time you change the oil. Like your car, fresh oil requires a clean filter to be effective in lubricating your outboard.
• Ask your dealer to recommend the correct oil and filter. Typically, the factory oil and filter is the way to go. A few bucks saved on aftermarket oil and filters may cost dearly if you pick the wrong stuff, and it can void your warranty.
• Read your manual, and confer with your dealer, on the best way to extract the old oil from your engine. Some engines have a drain plug; others must have the oil sucked outward through the dipstick tube. For that, you'll need a special oil extraction pump, which you can find at West Marine ( westmarine.com/oil-change-pumps ).
• If you're attempting to change the oil when your boat's in the water, be aware of the potential consequences of spillage, which could land you a hefty fine.
• Properly dispose of the waste oil and filter, but not before you rub a little of the recently removed oil between your fingers. If the oil feels at all gritty or has a burnt smell to it, it could be an indicator of problems. Have the shop look at it.
• Carefully document each service: date/time, hours (if possible), type of oil and filter used, disposal method, old oil condition, and any other pertinent conditions.
• Ask the boatyard if you can change the oil on their property — not all yards will allow you to do your own work — and ask if they can recycle the oil for you.
• Don't use automotive oils and filters. Marine oils are specially formulated for harsh and wet conditions, prolonged periods of inactivity, and much higher exposure to potential rust and corrosion.
• Follow factory procedures and advice to the letter.

Environmental Matters

Disposing of used oil can be a messy problem because it's considered hazardous waste. Petroleum products are toxic to fish, plants, and animals, and if they're not handled properly they can contaminate soil and waterways, resulting in environmental damage, costly cleanup, and possibly even federal fines. Luckily, used engine oil can be easily and safely recycled. Ask your marina if it offers collection of used oil for recycling, and if it does, be sure to follow its guidelines for handling it. If this isn't an option, check with your local automobile repair shop or auto parts store, or visit earth911.org to do a search near your location.

Did you know that your oil filter can be recycled, too? Oil filters are made of steel, which is America's number-one recycled material. If all the filters sold annually in the U.S. were recycled, enough steel would be recovered to produce 160,000 new cars! You can also search for local recycling drop-off locations at the Earth911 website .

Best Motor Oil for Your Boat’s Engine

• Post author: Trey
• Post published: June 27, 2019
• Post category: Boat / Marine

Have you ever really thought about the differences in how your boat’s engine is used compared to your car’s engine? Do you know why it’s important to understand these differences, so you can choose the best oil?  This article will talk to you about some of these differences and introduce you to the best synthetic motor oils on the marine market, manufactured by AMSOIL. 

Download a Factory Catalog

What’s different.

The wet and sometimes salty environment it operates in, the amount of use it gets, high RPM’s and constant load are just a few.  Compared to your car’s engine, these are some of the harshest environments that can be encountered. Add to this list, that maintenance is usually not at the top of the priority list.  So, when you choose an oil for your boats engine, using one that is designed to give you the best protections in those conditions is a must. 

Whats high stress

Consider that a marine engine powering a boat at 30 mph runs about 5,000 rpm. In contrast, an automotive engine powering a car at 60 mph runs about 2,000 rpm. This higher stress causes traditional oils to break down and lose viscosity. This leads to deposit formation, reduced power and eventually engine failure.

How does rust come into play

Due to constant exposure to humid, wet environments, marine engines are prone to rust and corrosion. Rust on engine parts acts like sandpaper, scouring bearings, the cylinder wall, piston rings and other components, while aluminum pistons and other parts can corrode. Rust and corrosion reduce engine power and eventually cause catastrophic failure. Rust protection is not natural to motor oil; it comes only by design from the additives added to it.

When a marine engine sits in storage for the winter season, all the acids and water introduce to the oils can lead to rust formation on the internal parts. When the engine starts up again, damage will caused to the cylinders and bearings. Extending your rust protection to the off season comes into play.

Who makes oils

Reading a recent article about marine engine oils, I had to laugh when the author started talking about engine makers formulating oils.  Engine makers don’t formulate motor oils, the oil manufacture’s formulate oils.  Just as designing engines to meet the newest standards is a continuous process with lots engineering and testing, Formulating oil to meet the latest standards in a variety of operating environments takes the same amount of engineering and testing.  On top of all that goes into developing oils, testing oils is expensive and ongoing. Most people don’t understand that every time and oil formulation is adjusted, it must go through the tests all over agin to be re-certified.

Who makes the standards

The National Marine Manufacturers Association (NMMA) developed the standards and testing procedures for certification for Marine Engine Oils.  These certifications are FC-W, FC-W (CAT)  and the TC-W3.  The goal of these oil certifications is to reduce emissions, increase fuel mileage and design oils specifically for the marine environment. 

Here is a link to the NMMA if you want to read more about them.

Fc-w and fc-w (cat).

These oils are designed for the 4 stroke marine engines being produced.  The FC-W (CAT) category is for the newest marine engine technology that has exhaust after treatments to further reduce emissions.  These FC-W (CAT) oils are catalyst compatible. 

Four Stroke Marine Oil Certification Testing

Who develops the tests and what are they testing for?   Directly from the NMMA site: “Working with the NMMA, industry leaders in lubrication technology developed testing criteria for this marine four-stroke oil. These criteria include bench tests for viscosity, corrosion, filter plugging, foaming and aeration. In addition, the oil must successfully pass a 100-hour general performance engine test.”  

The FC-W (CAT) certification takes into account the need to protect the catalyst in marine engines with exhaust after-treatments in addition to all the normal performance criteria of the FC-W oils.

TC-W3 

Two stoke oils lubricates engine parts as it passes through the engine and is burned off with the fuel.  Two stoke oils can be either mixed with fuel or injected in to the combustion chamber with the fuel.  The long term goals for two stroke engines have been to reduce the amount of oil used in mixes and to reduce the amount of emissions containing the unburnt oil while increasing engine life.  

As two stroke engines continue to move to higher cylinder temperatures and increased compression ratios to improve performance, it’s critical to use oils that meet TC-W3 specs.

How are TC-W3 oils tested

From the NMMA, “The TC-W3® oil standard is a performance-based qualification program. The requirements include various bench tests for fluidity, miscibility, rust, compatibility, etc., as well as engine tests to evaluate the prevention of ring sticking and carbon buildup on pistons and other engine parts. The engine tests include one Johnson 40 hp and two consecutive Mercury 15 hp tests, all of which are run under severe conditions for 100 hours each. Two additional engine tests are also conducted to ensure a high level of lubricity performance.”

Why is this important

These specific tests and criteria are needed because of the high loads, high speed, exposure to high levels of humidity and salt water found with marine engines. Most standard oil tests don’t work for these conditions. So tests for oils specific for the marine environment are important for the current and future development of marine oils.

Why use AMSOIL marine motor oils

AMSOIL is known as the leader in the Synthetic Motor oils.  They have been developing, producing and pushing the limits of synthetic motor oils for over 45 years.  They take their research and real world data from their involvement in automotive, racing, marine and other industries to improve all their products.  Now, AMSOIL also has research from one of the most demanding industries, Wind Turbine gear box oil, to add to their line up. In addition to all the testing for API/NMMA and other industry certifications, AMSOIL has independent lab testing and conducts real world field studies of its products in use. They then publish the results of these studies for everyone to read.

Why this matters to you the marine engine owner

AMSOIL is the Factory Fill in over 50% of the gear boxes world wide for wind turbines.  When one of these gear boxes fail, it costs over $500,000 to repair or replace.  AMSOIL has had such great success in this market with reducing failures, that they are in talks to increase the number of factory fills they do.  What this does is gives AMSOIL amazing research and data, in one of the most demanding operating environments, to apply to the other oils they manufacture for other industries.  The harsh operating environments of marine engines being one of those other industries.

Is Ford Hiding an Oil Leak Problem On the Maverick?

" This video started out as an instructional oil change video for my Ford Maverick Tremor but quickly detoured into disaster. I was not expecting to have these problems ," stated by the owner of a new Ford Maverick in a recently posted The Maverick Resource YouTube channel episode.

The problem? An oil leak was found after just the first 3,500 miles of his truck, but not until he removed the truck's engine splash shield (i.e., skid plate) was it noticeable. This begs the question: Is one of the reasons manufacturers install splash shields to help hide pesky oil leaks in new vehicles?

Related article: Top 5 Best Trucks to Buy for Reliability and Value in 2025

Why Vehicles Have Splash Shields/Skid Plates Today

A vehicle's engine splash shield is a panel designed to protect the underside of the vehicle's engine and other vital components from water, corrosive materials, and road debris. Typically made of plastic on sedans and metal on trucks for off-road adventuring, the concept seems reasonable.

Aside from protecting the engine from road debris, the practical reasons for installing splash shields include:

• Improved Aerodynamics: By smoothing the airflow under the car to achieve better fuel efficiency and reduced wind noise―especially at higher speeds.
• Corrosion Prevention: In the Rust Belt regions, splash shields help prevent water, snow, and salt from splashing into the engine bay, reducing the risk of rust and potential corrosion of electrical components.
• Improved Noise Insulation: Splash shields act as a sound barrier, making the cabin quieter for passengers.
• Temperature Regulation : In some designs, splash shields can help regulate engine temperature by guiding airflow under the vehicle and around the engine.

However, the last (but not least) reason is Environmental Regulations. Splash shields are designed to prevent oil or other fluids from leaking directly onto the ground in case of a spill, helping manufacturers comply with environmental regulations.

Or is it also to hide a telltale leak?!

Problems Owners Have with Splash Shields

While splash shields have their pluses, not all owners are happy with them.

Problems with splash shields include:

• They make changing the motor oil more difficult as a barrier to complicate the task.
• The oil drain plug might be moved from the traditional bottom port to a side port to make room for the splash shield.
• Service techs will eventually lose the bolts securing the splash shield to the car and do not replace them, leaving the shield flapping and eventually breaking off.
• Owners cannot take a quick or easy peek under the engine to investigate a potential problem.

Follow along with the host of the video that began as an instructional video and became a warning to Ford Maverick Owners about why it is a good idea to DIY your truck's first oil change .
