Alternate fuel ready?
 

Is there any way to tell if your cars are able to run on e85 (ethanol)? Cause if I could pay 20-25 cents a gallon that would be magnificent. Or is it just put a few gallons in and see how everything pans out?

If your engine isn't setup to take E85, it won't work. Something about the gaskets and seals in regular gas burning engines not agreeing with E85. We went over it in one of my auto tech classes a few years ago at college. Some people add something like 10% acetone, but it doesn't really help (they tried it on Mythbusters). Maybe someone out there makes a conversion kit...it probably wouldn't be too expensive seeing as how nothing major needs to be replaced.
