put 27 gallons of e85 in it yesterday, after 3-4 tank full's the mileage has only dropped by 1mpg (so far) mine is really slow to change
premium is $5.09 at the cheapest place in town and the 1 station that has e85 is 4.19
still haven't been able to figure out what the slop is, need to bring down some interest free debt before I spend more money.
I do have some HID's to wire up in the wife's K2 probably tomorrow

Does E85 run on the same tune as 91?
