Leave only 20 gallons or so in the tank but add octane booster to get it up

down.

Octane booster is only good for five points, or so. Triptane has a
rating of 170 when blended with tetraethyl lead. That is as high as it
gets. Propane is 100, methanol and ethanol about 110 as is toluene.
Acetone is over 100. So called low lead 100 avgas is 115 and is the
highest you can buy from a pump. The closest small town gas station
has racing gas during the season, but I don't know how it rates. There
will be a quiz.
