What fuel do you use poll
 

90-93 with up to 10% ethanol

90-93 non-ethanol

93+ racing fuel

E85

Other

it's called "Super+" here, 98 octane and up fuel. the two bigger fuel chains, Aral and Shell, have 102 and 100 octane fuels on tap, I usually go for the Aral stuff with 102 octane.

Shell 91-VPower. Cali, loaded up with ethanol

Shell 93

I have only used shell 93 v power since I've had it and its all I ever used in both my s2000's and my evo x. It's the best fuel available in my area

Sunoco 93 (10% ethanol), usually.

If I could find gas without ethanol I would find it, but in California that's hard to find. So I'm at 91 Octane and voted with 10% ethanol.

93 w/ ethanol. I with there was a non-ethanol station near me, but the closest one is nearly 30 miles away, and you have to be a member of a yacht club to fill up there.

93 octane V-power only, has ethanol

I thought this would be a great topic to discuss, I just switch from using 92 at chevron with up to 10% ethanol to a Conoco 90 non-ethanol. It is .50 cents more that the premium 92 with up to 10%. I think is really makes a difference in throttle response and power in general. I am on my second fuel tank of it and the mpg is up also, I'll give it more time before I give a number of how much but it's at least 1-2 mpg ave better

which one is the 93 octane you get from QT?

E85 now :)

I use 94 octane from Chevron.. Its not racing fuel though.

The octane ratings are tad bit different for the international users!
