Mercury 4-Stroke Marine Engine Oil – 1L – 8M0078637

Protect your marine engine with Mercury 4-Stroke Marine Engine Oil 8M0078637. This genuine Mercury OEM SAE 10W-30 marine engine oil is specifically formulated for use in Mercury outboards and other 4-stroke marine engines.

Unlike automotive oils, this marine-specific formula is engineered to withstand the high RPM, heavy loads, and corrosive environments common in marine applications. It provides excellent wear protection, corrosion resistance, and viscosity stability to help maintain engine performance and extend engine life.

Key Features

• Genuine Mercury Marine OEM 4-stroke engine oil

• SAE 10W-30 viscosity grade

• Advanced marine additive package for corrosion protection

• Maintains viscosity under high heat and heavy engine loads

• Helps reduce internal engine wear and friction

• NMMA FC-W and FC-W Catalyst Compatible certified

Marine-specific oil formulas provide better corrosion resistance and shear stability than standard automotive oils, making them better suited for marine engines operating in humid or saltwater environments.

Function

Engine oil lubricates internal components such as pistons, bearings, and crankshafts while helping control temperature and reduce friction.

Using Mercury marine oil helps:

• Reduce internal engine wear

• Protect against corrosion caused by moisture and saltwater

• Maintain engine cleanliness and lubrication

• Ensure reliable operation at high RPM and heavy loads

Important Compatibility Note

Always verify the recommended oil viscosity in your engine owner’s manual. Some Mercury engines require 25W-40 or other marine-specific oils, depending on model and operating conditions.
