Newbie here, just bought a 1938 Ford Standard and runs great. I'd like to keep it that way. I've seen some posts touting Marvel Mystery Oil (MMO), which I will start incorporating, but has anyone tried using their Marvel Classic Motor Oil, specially formulated for classic cars? Looks like it may be a new product as I can't find much info on it.
