Octane ?

BTW I wouldn't use 87 in any of my performance cars just the DD

how does anyone know the 87 octane doesnt contain ethanol?

Each state has it's own labeling requirements but in Nebraska anything containing over 1% or higher of alcohol in the gas has to be labeled.

I'm not far from the original poster and around here shell has 91 with no ethanol

Bison I agree, however my question is more of which is better. I am in Canada and we have 92 octane with no ethanol and 94 with up to 10 % ethanol

We spend so much time and money on these cars and then we have a discussion on buying 87 octane because its cheaper?

LMAO

Not looking for what is cheaper only what is better If I was looking for cheaper I would sell the car and take up a none motorized hobby

More octane will reduce detonation tendency and is always better if cost is not a factor. More cylinder pressure can be used without detonation. Anything that allows an engine to run higher cylinder pressures without detonation will give an advantage.
