You are using actually a 1/3 more
typically you will see 15-17MPG if you dont drive like a jack ***.
however with the price of E-85 it is a 1/3 cheaper than 91.... so you will have to fill up more but your fuel costs are equal to 91.
105 octane at 91 fuel cost=bueno.
there are guys running E85 in sub zero climates and not having the problems that are being told.
but then again I have a ICS switch and i switch in between maps.

Yea that is good info... However, I would not say that you use 1/3 more... i was getting 17-19 before, now i get 16-17. You can also put a Ethanol content gauge on your car that will tell you your exact percentage of ethanol in the tank.
With our climate here you dont really have to worry about the cold thing. As far as oil... I have done quite a bit of research on this one.. i have been having mine analyzed every 1k miles since the switch just to see how much fuel ends up in the oil and if there is any excessive wear due to the fuel. All is good to go 4k miles and i should have the results back from 5k in a week.
I still only fill up once a week.. but now instead of spending 46 dollars i spend 34.

I've been using the same map i was using for 100 and where before i had a little knock somewhere i now have none at all. I didn't upgrade a thing except i already had a walbro installed. The car runs fine except a CEL came on of P0134. Might be cause i'm not tuned.
What's up everyone, I'm moving to vegas in the next couple weeks and need to get re-tuned for the wonderful 91 octane you guys got there. Previously tuned on 94 octane, any recommendations for tuners?
your using e85 on a 100 tune... thats not the smartest thing to do. Your gonna be running pretty lean. The reason you need to retune is to get the injector scaling correct.
