That sucks. Although in the old 12 second gtp I was running 87 all of the time .

We've had a recent change in our premium fuels in WI. Many stations up here are now offering ethanol free 91 premium. The department of Weights and Measures finally caught up with the 10% ethanol thing and relized that stations were selling 93 w/ 10% ethanol added, effetively giving it a higher octane level than listed. My undertstanding is that the lower grade fuels, 87 and 89, have a lower octane level before the ethanol is added to them. Once the fuel manufacturer adds the ethanol it brings the level up to the advertised number.

Kinda of interesting I thought, although I've never noticed much difference in milage or performance by using either 93 w/ 10% ethanol, or 91 w/o. I know for a fact though that folks down south seem to have better quality fuels though. I have always got better milage on the fuels south of Tennesee, usually 2-4 MPG better.
