E85 will never take off when it costs about a $1,000 more over a year vs. gas. I also found it funny that they didn't list the Sport Trac as an E85 vehicle. Lots of GM vehicles though....:blink:
All most all gasoline sold in the USA has some Ethynol i(up to 10%) in it. Unless your vehicle has a Flex-Fuel engine you cannot use more than 10% Ethynol or you will ruin the fuel system.
