Can you use synthetic oil in a Mercury 4-stroke outboard?

Can you use synthetic oil in a Mercury 4-stroke outboard?

Synthetic Blend 4-Stroke (25W-40) Outboard Oil Mercury 25W-40 Synthetic Blend Outboard Oil meets the stringent marine operational requirements of all of Mercury’s new 4 and 6 cylinder models. First in class for all FC-W durability test properties with industry leading internal Marine engine corrosion protection.

What kind of oil does a Mercury 4-stroke outboard take?

FC-W FourStroke (25W-40) Oil Mercury’s FourStroke oil technology outperforms automotive oils in marine applications because of its specialized additive package designed for marine engines. 25W40 is recommended for all marine engines. Things to know about this oil: For use in all four-stroke marine engines.

Is Mercury 25W-40 Synthetic?

Mercury’s 25W-40 Synthetic Blend headlines the new Mercury four-stroke lineup. Mercury 4-stroke oil features: Best-in-industry wear and corrosion protection. Maintains peak engine reliability and performance.

Is Marine 4 Stroke oil different?

Use the right lubricant —Marine and auto oil are not interchangeable. Because four-stroke outboard engines run faster than car engines, spend long periods running at extremes of speed and can spend long periods out of use, they have very specific requirements for anti-wear protection that car oils do not provide.

Can you use car oil in a 4 stroke?

This is one of our most frequently asked questions and the simple answer is yes, as long as it does not say energy conserving on the label. Because cars need the extra mileage there are additives in the oil that is there to reduce friction.

What kind of oil does a Mercury 115 4 stroke take?

SAE 10W-30
This Mercury oil change kit contains Mercury SAE 10W-30 Marine Engine Oil which features high-tech, anti-wear additives to provide over 30% better camshaft wear protection and greater corrosion and oxidation protection.

Can I use car oil in my outboard?

Automotive engine oils have a pretty easy job compared to marine engine oils. They are blended for mileage, emissions and efficiency and are not suitable for use in marine engines.

Can you use 2 stroke oil in a 4 stroke engine?

2 stroke oil is not a suitable 4 stroke engine lubrication oil, so the bearings of the 4 stroke would not be well protected if used in this way. The oil as such, would not immediately “damage” the engine, but extended use could lead to increased wear.

What’s the difference between 15w 40 and 25W-40?

Technically speaking, 15-40 oil is going to break down faster than 25-40 oil. They use additives to stretch the viscosity ratings. So 15-40 uses more additives than 25-40. It’s the additives that break down the fastest leaving you with oil closer to the base number, 15 or 25 in this case.

Can I use 25W40 instead of 10w30?

The Merc literature for this motor recommends two different synthetic oils: 10W-30 and 25W – 40. What are the pros/cons of 10W-30 compared to 25W-40. If your outboard is one of those that “makes oil” due to fuel getting into the oil, 25W40 will probably tolerate more fuel dilution.

What type of oil for Mercury 4 stroke?

FC-W 4-Stroke (25W-40) oil Mercury’s 4-stroke oil technology outperforms automotive oils in marine applications because of its specialized additive package designed for marine engines. 25W40 is recommended for all marine engines. Things to know about this oil: For use in all 4-stroke marine engines.

What oil does mercury use?

Mercury is recomending the optimax oil because it is Synthetic. The reason is because they have found that ethanol removes the protective coating of the oil in the engine.

What is Mercury outboard?

Mercury Marine’s primary business is outboard motors. Mercury Outboards, 30 Hp and less, are made by Tohatsu in Japan. Mercury Marine builds 40, 50 and 60 horsepower outboard motors in Suzhou , China. Mercury also manufactures engines over 75 horsepower at its facility in Fond du Lac in Wisconsin.

What is 4 cycle oil?

2-Cycle and 4-Cycle Oil. Because 2-cycle oil burns with the fuel, it must be more refined than 4-cycle oil, and it must contain a number of additives. These include detergents to clean varnishes and carbon deposits from the combustion ports, anti-wear agents to protect moving parts, biodegradability components and antioxidants.
