You are correct, I forgot the main ''meat'' of the package, it does take on E-85, but the Ford site also states that the Flex Fuel cars are equiped with low resistance tires, fully covering hub caps and a spoiler. I think those can be placed into the aero dynamical section of the flex fuel package. I agree tho, that the main appeal of this package would be the ability to use E-85...if available. I am not saying it's not avalable around here, I'm just saying that I acheived the same numbers with the same reg fuel on the same roads conditions, on the same comute and driving the same way.
I never had a FF car before, that may be the reason I am not fully aware of the E-85 availability. I mean, it must be available, 'cause why sell Flex Fuel car around here then ??
