Can I put E-85 Gasoline in a 2005 Ford Five Hundred?

Only if it's a Flex Fuel model. But why would you want to run 85% Ethanol? Sure it's cheaper but you also get worse mpgs.

NOT recommended. E-85 is 85% ethanol, and if your car is not specifically designed and manufactured to run on that fuel, it will cause serious problems.

Sure, if you want to spend more than that POS is worth on repairs. Your fuel system MUST be specifically designed to use E85.

Can you? I don't know of your capabilities. The question is, should you?

No…
