Description Customer Questions & Answers Shipping
NMMA FC-W Yamalube 4M certified marine engine oil. Automotive oils do not usually run at 6000rpm but Yamaha outboard engines were designed to run at full throttle (5500 to 6000 rpm) all day long. At this speed it is critical that engine oil not foam. Foaming reduces lubricity which can lead to wear and over time this can lead to failure. Yamalube 4M FC-W has the best blend of anti-foam technology available.
