[Healeys] Fw: Marvel Mystery Oil

[Fred Crowley]

Yup b 100% castor oil. With respect to octane ratings I donbt have a clue
since Ibm using 110 leaded racing fuel. Maybe somebody with a bit of
chemistry behind them can comment. In chemistry class, I volunteered to light
the bunsen burner..

Great stuff Fred. I love that smell. Unfortunately using Castrol racing oil
means more frequent engine rebuilds as it gums up the works. Maybe a bit of
castor oil in the fuel is the way to go. Presumably though this will lower the
overall octane level. Or would the effect be insignificant.

Is it 100% castor oil that you buy?

  I buy castor oil in a gallon container (off the internet) and add a couple
of glugs (must be very precisely measured) to about 5 gallons of gas in my
vintage racing '62 3000. Depending upon who's asking:

  Other Racers: It adds substantial horsepower, improves the handling, and
reduces wear on the brakes
  Me: It smells real good, just like it was in the day when castor oil was in
the sump.

  The main reason I do this is that our sanctioning body here in Texas values
authenticity of presentation of the race cars. I may not be the fastest, but I
sure smell authentic (there's a lot of leeway for comments here!).

  A side effect I've noticed is that cylinder bore wear, vales, and rings show
minimal signs of wear. I built up the current engine in the car about 10 years
ago. With 6-7 hard racing weekends a year, the leak down is still less than
1%.

  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.
