Function

Marine engine oil lubricates internal engine components while helping manage heat, friction, and corrosion. The specialized additive package in Mercury marine oil is designed specifically for the higher loads and moisture exposure found in marine engines.

Using the correct marine oil helps:

• Protect internal engine components from wear

• Maintain proper lubrication under high RPM

• Reduce thermal breakdown of oil

• Prevent corrosion in marine environments

Important Compatibility Note

Marine engines require oils that meet FC-W marine certification standards. Always verify the correct oil viscosity and specification in your engine owner’s manual or by serial number before use.
