Just want to point out that Marvel Mystery Oil and Marvel Air Tool
Oil are not the same thing.
I use Castrol 20W50 in my B's engine, OD tranny and carb dashpots.
Never had any oil-related trouble with any of them. Sometimes I think
enthusiasts tend to over-enthuse about "trick" products.
Cheers,
CR
