Maybe the reduction in power and fuel eff only affects larger engines (although I can't imagine why).

Keep in mind, my truck is a '69 C10 with 3.73's in the rear, 3 speed auto with no overdrive, 357 smallblock with a Holly 650, yada yada, but that stuff (NOT E85, just normal gas with 10% ethanol) makes it run like GARBAGE. What I was talking about though, was E85. You actually get worse gas mileage with it, which the only upside to that would be that its cheaper than standard gas, but around here (and alot of places), its only a little cheaper and doesn't really make it any better of a choice than normal gas. I'm not sure how the standard gas with the 10% ethanol helps gas mileage on a fuel injected motor, just mine, and I get worse gas mileage AND performance.

Set up your engine properly and you'll be surprised. You could either set an engine for more power or better efficiency, but the point of Ethanol specially the ones made from sugar canes, is the renewable factor of it. Doesn't higher octane gas have higher amount of Ethanol (Maybe Methanol) in it? I know E85 is 105 octane so it's almost like using 110 race gas.

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%.

The main point of Ethanol is basically it's renewable ability. I've seen the benefits of it (In many ways I may add ) in the automotive industry. To make it similar or more fuel efficient then gas, one would need to set it up that way. Most just use it to gain power and like you don't care much for gas mileage.
