Add to CartYamalube 20W-40 is designed for maintaining viscosity in 4 stroke outboard engines in marine environments. NMMA FC-W certified, this oil features rust inhibitors that helps keep you moving smoothly and increasing engine life. Yamalube utilizes anti-friction protection to help promote efficient fuel economy and increased performance. Additionally, Yamalube 4M FC-W has the best blend of anti-foam technology available. This is important, as foaming reduces lubricity which can lead to engine wear and, over time, failure.
