Comments about West Marine Premium 4-Stroke Oil, 10W30, Gal.:

This oil made my Yamaha f115 outboard run very smooth and is fcw nmma certified which is what Yamaha requires in there engines I have noticed a big difference at idle and overall performance through the rpm range and seems to keep engine running clean this is my new oil from now on but I do recommend still using a Yamaha oil filter this oil is a great value for the money and in my opinion is better then yamalube the west marine 10w30 premium outboard synthetic blend is a really good quality marine oil.
