Choice of Fuels?

[Kelly Padfield]

Looking at the different premium fuels around here I seem to have a choice of 91 octane without ethanol or 94 octane with 10% ethanol. Which one is going to be the best to run through these cars? Now my SHO is bone stock right now but I plan to buy a tuner sometime this year and do the thermostat, CAI, 3bar map and tuner all at the same time.

Tough choice! Where I live I can choose from 93 with up to 10% ethanol or 90 without ethanol. The 90 without ethanol is considerably more expensive than the 93 with. I go with the 93 for my car and the 90 without for my yard equipment.

What's the price of your two options?

118.9/L for the 91 and 117.9/L for the 94

I'd go with the 94, should be fine. Otherwise, you can run the 91 tune, but where's the fun in that Ethanol fuel is common here in the U.S., ethanol free being a pipe dream for most of us. So I am sure tuners are well aware of what they can do to level the playing field. Wouldn't worry about it.

94 octane with 10% ethanol is perfect.
