Been posts about Marvel Mystery Oil.

Aren't these both just very light weight oils put in the gas tank?

Marvel Mystery oil has been around for a long time. I can remember 30 years ago, my grandfather pouring marvel mystery oil into the carburator to clean the carbon off the pistons. I don't know if it did more harm than good, but he swore by it.

Seafoam is a blend of light lubricant, naptha cleaning solvent and isopropal alcohol. This is according to the factory rep that came to our parts store. Craig :cheers:

Many of the old car guys (mine's a 52 Studebaker truck, in other words old cars, not necessarily old guys) use the Marvel Mystery Oil to turn over old haven't-been-turned-in-years motors ---- I squirt it into the spark plug holes on a motor I think may sit for a while.
