Yamalube 10W-30 FC-W Marine Engine Oil – Quart – LUB-10W30-FC-12 – OEM

Yamalube 10W-30 FC-W Marine Engine Oil is Yamaha’s marine-specific lubricant engineered for 4-stroke outboards operating in high-rpm, high-load environments. Formulated to meet NMMA® FC-W® certification standards, it delivers dependable protection against wear, corrosion, varnish, and sludge while maintaining proper lubrication under sustained throttle conditions.

Unlike automotive oil—designed for engines cruising around 2,500 RPM—outboards commonly operate between 4,500 and 6,000 RPM for extended periods. That level of continuous stress can quickly break down standard automotive oils. Yamalube’s FC-W formulation is built to withstand moisture-rich marine conditions, resist foaming, and provide the durability required to protect your outboard during demanding operation.
