Compared to the fuel I have been buying, the truck seems to run with a little more pep. Could be the placebo effect - not sure.
Is there any downside to continued use of E85? Its about $ .30 less than standard 87 octane fuel. Can't tell if there is a MPG penalty yet since the truck gets crappy mileage anyway.

Yes. You will find your wallet is lighter as you travel to the gas station more often.
Ethanol has about 30% less energy per gallon. Did you pay 30% less for the fuel?
