– In order for an oil to be approved by the NMMA® to hold its highest rating for marine engine oils, FC-W® (Four Cycle – Water cooled) it must pass a multitude of tests.
– Passenger car oils don’t pass these tests, which is why it’s important to use NMMA®-Certified Yamalube 4M FC-W®.
– Automotive oils do not usually run at 6000 rpm.
– Yamaha Outboard engines were designed to run at full throttle (5500 to 6000 rpm) all day long.
– At this speed it is critical that engine oil not foam.
– Foaming reduces lubricity which can lead to wear and over time this can lead to failure.
– Yamalube 4M FC-W® has the best blend of anti-foam technology available.
