Your right, E85 is 105 octane, but it only really makes it worth the extra money if your running FI or super high compression 12.0:1 or higher, and it actually requires more E85 than it would normal gas because of how it burns, which gives you worse gas mileage, and around here, the cost is around only 10 cents less a gallon than regular unleaded. I know if tuned properly, E85 is better than unleaded for FI, but like I said, thats the only way it proves useful for power (my only real concern). I'm not so much concerned with things like gas mileage to be honest.
I wasn't saying I run E85 in my truck, I just usually have to run unleaded with the 10% ethanol mixed in because unleaded around here without ethanol is almost impossible to find, and for some reason, no matter what I do, it just makes it impossible to get it tuned 100%.
