Thanks Boo! Took a look at it. Sure does seem that a lot of people are using the multi weight stuff huh?? Not sure though even after reading all that what I'd be best at using. Fact is this is an engine with 184,000 miles on it and it seems like many of those engines that people were talking about on that link you gave me had newer engines?? Of course mine is a straight 6 from 1950....
