Provide your boat engine with the protection it deserves with our high-performance 25W-40 engine oil, specially developed for inboard engines. Our engine oil offers excellent efficiency and long-lasting protection for your engine.

Adapted for Extreme Temperatures and High Loads

Our multi-viscosity 25W-40 oil is carefully developed to counteract viscosity breakdown in extreme temperature conditions and under high loads, ensuring smooth and efficient engine performance.

Superior Lubrication and Protection

This oil has been tested and approved for use in both gasoline and diesel applications. It provides superior lubrication and protects the engine from corrosion and wear, which is crucial for the engine's longevity and operational reliability, especially at very high operating temperatures.

Meets Strict Industry Requirements

Our engine oil exceeds the latest API service requirements SJ, CF-2, CH-4, and is highly recommended for use in leading boat engine brands such as Mercruiser, OMC, and Volvo Penta.

For owners of MerCruiser inboards with a catalytic converter, we recommend our 25W-40 Synthetic Blend (product number 8M0078623) for even better protection and performance.
