YAMALUBE® 5W-30 4M MARINE SYNTHETIC ENGINE OIL

NMMA® FC-W®-certified, Yamalube® 4M Full-Synthetic is our highest-performance, four stroke outboard formula. Features all of the benefits of mineral oil-based Yamalube® 4M, but with a full-synthetic formula that dials up lubricity, lowers friction levels and improves fuel economy.

• 5W-30 weight provides excellent lubrication in all climates
• Recommended primarily for the four stroke VMAX SHO®, but works well in our other high-performance four strokes (e.g. V6 Offshore and F70 models) and in other brands of marine stern drive and inboard engines
• Specific marine additives combat rust, corrosion, varnish, and wear; all while providing high levels of bearing protection, resistance to foaming and lubrication
