Product Description
About This Item
Introducing the Yamalube-20W40 NMMA FCW Low P Quart - the ultimate engine oil for your outboard motor. This H4 Bigger 20W40 4-M Outboard Mineral FC-W Engine Oil is specifically formulated to meet or exceed the industry standards set by NMMA FC-W for outboard engine lubrication, corrosion protection, and oil dilution (with fuel). Unlike automotive engine oils that are designed for lower RPMs and less demanding conditions, this Yamalube oil is made to withstand the rigorous demands of outboard engines.
While most automotive engines cruise at 2500 RPM, outboard engines can cruise from 4500 RPM to 6000 RPM.

With our exclusive additives and NMMA FC-W approved formulation, this Yamalube oil provides the ultimate protection and performance that your outboard engine needs. Don't compromise when it comes to the life of your engine - trust Yamalube-20W40 NMMA FCW Low P Quart to keep your outboard motor running smoothly and efficiently. Order your Yamalube-20W40 NMMA FCW Low P Quart today and experience the difference it can make in your boating experience.
