Marvel Mystery Oil
Marvel Mystery Oil
(OP)
For all practical purposes, 80 octane aviation gasoline is no longer available, forcing the Cub driver and other to choose between 100LL avgas and 87 octane automotive gasoline (assuming that he has the necessary STC and that "mogas" is sold at the airport). Each fuel has its own problem. Despite the low-lead designation, 100LL contains too much lead for the older, low-compression engines. Mogas, on the other hand, doesn't have enough: some lead is needed to lubricate the valves.
Many other aircraft owner are using Marvel Mystery Oil to reduce the buildup of lead from 100LL. Does any one have information or testing of this mystery oil in type certificated aircraft engines as an additive?

Several aviation supply companies advertise the oil for sale and in at least once case it was the cause of an accident NTSB Identification: NYC02LA181. When added to aviation fuel it will turn fuel pink to red in color.
I was hoping someone has done some research on the oil as an additive and what happen at altitude and if it does cause detonation.

The airplane had a can under the rear seat when I bought it, and I ignored the hint. After having 2 stuck valves on a cross country and enough aggravation to get the engine sorted out, I started using Marvel and never had a hint of the problem again.

We used it on our J-2, a couple of Cessna T-50's and, a Mac RCAT powered Benson---never had a problem of any sort that I recall. I even used it in the total loss lllubrication system of my Judson supercharged MG-TD.
Looking back some 50 odd years, I think we were victims of wishful thinking. Today I find that MMO is great for lubing pneumatic tools and water proofing my work boots!
