I like Amsoil in my newer bikes, as it keeps the sooty crud from building up in the valve covers and other nooks. I don't know about using it in the R-65, though...I'm thinking about that oil leak I have in one push-rod seal. Might be unrelated, but it is odd that it popped up when I switched from Dino oil.
Definitley use it in the cars...once a year oil/filtre change!
Remember a couple of years ago when they change all the car oil to SJ ratings? I understand that at the time they removed a lot of the zinc and whatever else was helping our engines last longer. Car engines can handle it better due to cooler running temps, but bikes were chewing up microscopic metal on the new oil. Check the web and see if I have this right...this old brain of mine might be going soft! Ed out.
