ok so it may add power, etc...but why do you ppl run e85 if the manual specifically says on p195:
"Do not fill the tank with E85, i.e. fuel containing 85% ethanol, nor FlexFuel. Otherwise the engine and fuel supply system will be damaged."
i already know your counterarguments will be that "it means you shouldn't run a full tank of e85, but a couple gallons won't hurt"...but still, thats not a valid counter argument
