I acquired a 5-gallon 'drum' of Marvel Mystery Oil a long time ago.
I don't know if it's a placebo or if it is actually helpful but I used a
little as a fuel additive in every fill up of my vintage airplane - and
Farmall tractor also - for years. The Continental engine in the airplane -
and the Farmall engine too - ran great. So I still have a little left and add
a couple caps full in the Austin Healey gas tank once in a while. Doesn't
seem to hurt a thing.

Subject: [Healeys] Marvel Mystery Oil
Hi all,
I've got a 1961 BN7 with 72,000 miles and to my knowledge, it's never
had an engine rebuild. I was thinking of adding some Marvel Mystery Oil
to clean out carbon deposits that I'm sure must exist. Naturally I'm
very cautious about what I put in my engine.
Has anyone ever tried this stuff and if so, what were your results?
Thanks in advance,
Steve 61' BN7
