Why is it important to use marine-specific motor oil for your boat ?
No matter if you have an inboard or outboard engine, these engines are designed to work with a marine-specific engine oil. The reason for this is pretty simple: unlike your car’s engine, a marine engine needs to deal with extreme conditions, including a wet environment, and in some cases salty conditions that automotive oil is not designed to handle. With higher RPMs and constant heavy loads, marine oils are formulated differently and generally contain 20-35% more additives than your typical car or truck oil. All of this with sludge prevention, corrosion protection and a thicker viscosity to ensure that your engine is not going to fail when you need it most.
The AMSOIL Difference
Our 100% Synthetic Marine Engine Oil is one of the best engine oils on the market for outboard and inboard engines. This engine oil comes in 10W-30 and 10W-40 and can handle the high stress and high RPM you see in sport boats and high-end PWCs. In addition, with enhanced rust and corrosion protection, your engine will be protected against the effects of both fresh and salt water. Plus, with NMMA FC-W Catalyst compatibility, this engine oil will work with any major boat engine manufacturer. We also offer our 25W-40 Synthetic-Blend Marine Engine Oil, which is perfect for those older engines that need excellent performance and protection from corrosion and rust.
