"HEET" fuel additive - ZR-1 Net Registry Forums

Corvette95 · 12-27-2020

I am only able to get 90 octane ethanol free gas here in Alabama. Fuel injectors have been upgraded and I know I "can" run regular gas but I choose not to. I let my cars sit between drives longer than I like. I bought a case of HEET for use as an octane booster, I tried to search the actual make up of it but didn't get any good information. Anyone here use HEET and if not, what would be a good safe octane booster that won't turn the fuel bad after sitting. Thanks!
