I want to get back in on this. My local parts guy carries Amsoil but which one to use? Am I looking at the regular ASL SAE 10W-30 Synthetic Motor Oil. None of the racing or high performance stuff they have. There are so many choices on their web site.
I also wanted to ask about the rating or classification seals on the oils. I know someone explained this to us with a chart or something but what rated oil is best or what should we be using for maximum life.
