In Merrill Wisconsin on south center ave teh Shell station has 91 octane ethanol free gas. It's .10 a gallon more than 93 octane premium and .30 a gallon more than 87 octane, both with "up to 10% ethanol". I'll be putting away my Daytona in a few weeks and won't have time to run any mileage experiments, but if they still have it next summer I have to see if I find a difference. I have a difficult time seeing it make enough of a difference in my van to make up for .30 a gallon. Anyone else know of any stations with ethanol free gas?
lol around here regular and occasionally midgrade is e10. the stations that have midgrade e10 have non ethonal regular gas. my chevette it makes a difference for some reason but its fully carbed no computer controlled anything. (might be the octane difference who knows)
my truck is a 95 so its obd 1 and i haven't noticed a difference that i cant attribute to driving/what i had to tow/haul that week...got 32mpg using e10 regular driving down to college(4.5 hours 250~ miles)
i think modern vehicles adjust so much to get that ideal A/F ratio and timing that it doesnt make a difference.
