I am not an engine guy at all.... That said, the mechanic I put my trust in says he can tell what quality oil has been run through an engine when he opens them up. I use the manufacturers recommended oil as it has all the additives. Yamalube and Ringfree religiously and my 1993 200hp is running strong. And I have been putting more than 400 hours a season on it for the four years I've owned it.
