What Octane Gas?
I know there are numerous threads about what gas and if premium is really necessary but i want to get a general idea of what gas is commonly used.

I now run Shell 91 exclusively, use to use Sunoco 93 it has up to 10% ethanol but fuel economy,power seem the same as with Shell 91 and I save 7-10 cents a liter.
In my old GTP with the 93 there was a noticeable difference over the 91 in fuel economy and power. I don't think rotaries like ethanol!

I've never used anything under 91 octane in my car.
If I could get 93, I'd use that.

Using octane rating to determine power output is useless. Gasoline formulations change from State to State, County to County and Brand to Brand. Formulations change from summer to winter. One station will work fine with 87 and across the street you will have problems with 89.
Just find a brand that works fine for you and stick with it.
