Same as Steve in MA.
AS a yut I used to mix toluene into SUN260.
Thought the L88, and the LT1 before it, needed it! Plus, those sweet smelling aromatic hydrocarbons..." Ooh Ooh that smell!" Ruined the needle in Qjet once, and never did it again.
PS, as a former biodiesel brewer and user, I ALWAYS use Viton lined fuel line anymore. EVERYWHERE. Including my rat I forget the SAE spec, 30R9 or something. Viton tipped needles, etc. I may suggest y'all consider that.
True that the use of corn alcohol in engines is another clusterfck brought to you by the unholy alliance of big corp farming ( ADM) and our politicians at public auctions, selling our representation to the highest bidder. You spendthat much ENERGY to distill booze, you best be drinking it. Methanols, isobutanols are WAY easier to make.
Isobutanols, as ANY chemist will tell you , are WORLDS better fro road fuels. We dont use Ethanol as race fuel do we? There are very good scientific reasons why.
SUN93 / 10% ethanol in the Chevelle. Havent done a compression check on the new mill, but the 427 @ 210 psi cranking needed octane. It's in a race car now, so it'll eat race fuel for the rest of its life.
So what type of fuel do you use? needs a "for which engine" qualifier. We only have 91 non eth around here. The small engines get that, but the rats cant handle it.
