I a thread over on iBoats, there was an ongoing discussion of a iffy engine. One of the posters said something about adding Marvel Mystery Oil (MMO). Got a rash of stuff back, but this was interesting:
MMO contains solvents such as such as kerosene, naphthalene, xylene, acetone or isopropanol. It always kills me that there's always people that think MMO (and other Snake-oils) are some kind of special double secret magic sauce that does something remarkable in an engine when added to either the oil or the fuel ...
Another poster responds:
Some years ago, MMO was added to fuel in an aircraft engine and the NTSB had the following to say about it at http://www.ntsb.gov/ntsb/brief2.asp?...02LA181&akey=1
According to the FAA inspector, the additive that was added to the fuel was Marvel Mystery Oil. An empty 1 gallon can of Marvel Mystery Oil was found in the operator's trash. Instructions found on the can stated that the correct ratio for mixing with fuel was 1 part additive to 100 parts fuel. The contents of Marvel Mystery Oil were 74 percent mineral oil, 25 percent stoddard solvent, and 1 percent lard.
Well OK, maybe you should not use MMO in an aircraft engine or aircraft fuel, but in an oil burner/beater, why not ...
The Stoddard Solvent will free stuff (
), and the lard will be poor mans AutoRX (bio-oils), so that's cause to go get some all by itself. I think it's a bargain for what it does
I have used it on and off for decades on oil burners and rough running engines. About 75% of the time it'll help in one oil change interval.
I have moved on to BG109 and my fix in a can
But under some circumstances, I'd grab a can of MMO and go for it again
