The manual says minimum 91.

10% Ethanol is nothing to worry about, and defo better than that 87 - leave that for old lawnmowers.....

I always run high test, 91-93 octane. If the manual says to run a minimum 91 do it. Cheap gas will do nothing but cause unwanted issues in these cars.

Is there any actual evidence or cases of ethanol-related damage? I know there was a lot of theorizing floating around about corrosion and water separation, but I've yet to hear of actual cases...

I mean if it really was a problem, the gas stations themselves would be the first victim.

You would be better with the E10 93 octane...although I ran mine stock on 87 and didn't have any issues with street driving

Mhm, in Bulgaria 95 is normal, we have 100, premium 105 I've seen. Let's say 95oct is around 1.20 euro, the 100 one is around 1.35 and the premium 1.5.. XD something like that

93 is pretty common here (eastern nc) but being a race county some places have 110 on tap!

How does it not compare to everyone else in the US using 87-93?

He's referring to Bulgaria.

In the US we use AKI (anti-knock index) which is an average of RON (research octane number) and MON (motor octane number).
In most of Europe, RON is used.

Where are you getting 110 in the US?

You don't need it for a NA 8.... or even a turbo 8 unless you are running more than 10-15 lbs of boost.

I honestly couldn't tell any difference using Shell 91 and Chevron 94.

I doubt a stock 8 is even tuned for anything above 91.

You won't notice a difference between 93 and anything >93 if you aren't tuned for it. Odds are, you won't notice even if you are tuned for it unless you're force-feeding your car.
