Marvel Mystery Oil?

[flyingriki]

Bill Greenwood - you pretty much nailed it. To some it's snake oil, to others it's magic oil. To me it's a pretty good oil thinner & sluge loosener on some engines immediately prior to oil change. It's an ok penetrating oil too. Except for what I just listed, I don't use it in my fuel or oil. Today's oils are very well formulated and far superior to what was available back in WWII. I agressively lean my long time since overhaul O-300 during taxi and flight and I don't have any problems with buildup/leading with 100LL. Same for the other old low compression engines I've flown.

Flyinriki - Instead of going to wherever you cut & pasted your posts, take a look at the MSDS - it lists the type of dichlorobenzene.

martymayes - the MSDS lists p-dichlorobenzene (1,4 dichlorobenzene). I'm just going with what is listed there.

Yeah: "...used as a pesticide and a deodorant, most familiarly in mothballs"..... just what I want in my engine.....! Oh wait...it has wintergreen in it. Gee that makes it much more effective.....for..... at least it'll smell nice.
