"Cop gas" - 85% ethanol fuel
 

Is it safe to run in an NA 12A? Discuss...

Thanks in advance

why would you want to? you will have to tune for it but yes it is possible. better get a wideband and an egt gauge :)

It will eat all your hoses.

And don't let it sit in the tank for very long...

That's known as E85. No you probably shouldn't run it in a 12A without some changes. A number of vehicles are sold that are "flexible fuel vehicles." That means they can run both regular gasoline or E85. I believe FFVs run some different gaskets/seals, oil and oil filter. Beyond that I don't think there are many differences. Many of the Chrysler vehicles with the 3.3-3.8L (eg. Caravan) are FFVs.

alcohol reacts differently in a rotary for 1, it leans out much faster, and alcohol mite not be compatible at all with the internal seals in the motor, i wouldnt do it personally

at http://www.racingbeat.com/FRmazda3.htm they have an engine that runs on methanol. If you call them or email them I am sure they will tell you what modifications you should do to run ethanol.

BTW I am sure this goes unsaid but becarefull ethanol is more explosive than most other car fuels.
