What gas engine manufacturer recommends 5w 50? That is some heavy viscosity oil. Nothing I own will be using it. I know some guys use 50wt oil in air cooled engines like a Harley. Even then I doubt the manufacturer recommends it.
My mistake, I meant 5W-40 someone above said that weight was OK to use. I plead ignorant about oil weight specs and always have been. Somehow the meaning of the numbers just doesn't stick with my 64 year old brain any more :?
