92 VS 93 octane - ZR-1 Net Registry Forums

32valvesftw · 04-09-2020

Do you guys think 92 octane without ethanol is superior to 93 octane with ethanol? I understand what octane means, its more of an ethanol issue, assuming upgraded injectors.

I'd give up that one point for ethanol free

Dittos on Steve. AND where you live, the DA at that altitude - even in the flat land, east of the front range - 92 octane would behave something like 100+ down here at 600 feet amsl. And, if alcohol free, that is a nice bonus!!

Two years ago I met a guy with a 2008 Corvette; he was bragging about filling his gas tank with leaded Cam-2. He said it ran great, but with the engine check light on all the time.

Does it help any to add some 104 or 108+ booster? Snake oil?

Got news for you. You can still buy Sunoco 260 and more. In 5 gallon cans. It will cost you though...
