Duke, a question...
don't laugh, I know its a pretty silly question...but if I've been using an oil like Penn 10W-30 for years in an older engine and now start using one of the "diesel" oils in it, is there any problem with that? I can't imagine there would be, but in a valuable engine I don't want to take anything for granted when making a change from what its used to.
