Most of the gas stations now have up to 10% ethanol in the gas. There are some (very few) stations that have straight gas with no ethanol. My grand prix with the 3.8 gets better mileage with the straight gas, not really sure about performance.
I'm curious if anyone has any experience with the 90% gas 10% ethanol vs 100% gas (93 octane for both)in a TTA? Thanks.
