Re: amsoil - good or bad?
my snake oil comment was based on the fact that when a dealer tried to sell
it to me, and me on it, he handed me a "comparison" sheet of different oils,
and amsoil synthetic was at the absolute bottom of the list when compared to
all the other "inferior" brands when it came to the A.P.I. ratings. I
pointed this little fact out to him and his answer was "oh, those ratings
don't mean anything". for the record, the valvoline all fleet plus that I
had always used was at the top of the A.P.I. ratings.
