It sounds like the overall "keep it smple" solution is brand name 93 octane pump gas with 2 quarts of Octane Supreme 130 per 42 gal tank (one ounce per gallon). I can do that! Thanks.
I wonder if there is a way to just buy the tetra ethyl lead from a chemical company without it being outlawed by the EPA?
$10 a quart. Cheaper than 100% race gas, but.....
