Yamalube 20W-40 4M FC-W Marine Engine Oil (Gallon) – LUB-20W40-FC-04

Yamalube 20W-40 4M FC-W Marine Engine Oil (Gallon) – LUB-20W40-FC-04

Protect your compatible four-stroke outboard with Genuine Yamaha Yamalube 20W-40 4M FC-W Marine Engine Oil LUB-20W40-FC-04. This conventional mineral-based, marine-specific lubricant is formulated to meet NMMA® FC-W® certification standards and provide dependable protection during sustained high-RPM and high-load operation.

Its heavier 20W-40 viscosity holds up well in hot weather, making it a popular choice for larger Yamaha four-strokes operated in warm climates like South Florida. Yamalube’s marine formula helps protect against wear, corrosion, varnish, sludge, foaming, and thermal breakdown.
