Marvel Mystery Oil. Ran it in my old 1948 Stinson airplane when oil consumption hit a quart an hour. Helped some. (Had 900 Hrs on a 1000 TBO Franklin engine).
I wouldn't dream of using it today, especially in a little engine. MMO is out of the 1930s and was widely used in aviation. A2jack.
Use it - it smells so good! It's a light weight oil with additives. In the 50's/60's it was all we had that would get into some of the places that the 30/40 wt non-detergent oils were stopping from getting lube. We used it in the fuel for the carburators that were gummed and in the crankcase for the rocker shafts that were stuck - and it worked. Today I still keep it in my shop, it's a great air tool lube and I have a '59 John Deere tractor that likes it, but not in the smart, or my other new vehicles.
you are right...it does smell good!
I'm glad to hear that it works well with air tools...and with the John Deere...
