MARVEL Mystery Oil (Feb, 1952)
I’m not really sure what they’re trying to say in this ad… I think it’s either: “Marvel Oil will blow up your car”, or “Marvel oil is made of atomic bombs”.
FOR POWER

JD,
Don’t know about the 18 years old rule. Sounds odd. An 18 year old can buy motor oil right?
The product was not recalled for quality. It was recalled to add the mandatory EPA statment label that this product (and just about every other additive on the shelves) did not meet 2007 EPA Ultra Low Sulfur requirements for use in diesel vehicles 2007 and newer.
Thanks for your continued use of Marvel. I assure you we have had no quality issues with Marvel Mystery Oil resulting in a recall. Only the re-labeling effort.

I have a 1949 Willys Jeepster with 4 cylinder L head engine. The engine runs well but I am getting some “blow by”. Will MMO help reduce the Blow Bye”? What would be the recomended amounts of MMO to add to the fuel and the oil ?

We used Mavel Mystery Oil to lubricate parts in photographic printers. It’s pretty good at staying where you put it.
