I only use Penzoil 50w..... but of course thats suggested because the motor is built. I've used the 25-50 from Penzoil, not sure if its because of my motor clearences or not, 50w seems to not heat up as quickly and runs cooler. Probably not suggested for a stock 500EFI? not positive though....

I guess if ya change it often enough ,before fuel dilution,or when its breaks down from high temps.I been running the Valv 40 for 16 years in different boat blower motors and have never had a bearing problem or oil related problem

I am sure that if I ran the sythentic lighter oil it might make 5 more HP but so would 10 w mineral base oil
