The Marvel Oil Company was founded in 1923 by Burt Pierce, inventor of
the Marvel Carburetor. His carburetor was standard equipment on eighty
percent of all vehicles produced after World War I.
Why did he give it the name Mystery Oil? Is it said that Burt Pierce
refused to divulge the formula for his new product and, when asked about
its ingredients; he would say "It's a Mystery", and the name caught on.
----------------------------------------------------------
This came off of the Internet via Google and looks like it's pretty
definitive. The Marvel Carburettor company was merged with the Schiebler
Carburettor and the Marvel-Schiebler Carburetor was widely used into the
40's AIR! The solvents in the oil seem to be able to withstand the
temperatures in older combustion engines and remove lead and carbon
deposits. These deposits no longer form in modern engines!
