I would like to know what kind of modification is needed if I add 20% of ethanol in the tank.

How will the Evo run with 20% of ethanol in the tank?

thanks

 

Considering most gas now contains up to 10% i can't seem that 20% would be that much more. The evo would probably run ****ty unless tuned for it. Supposedly you need to have ethanal approved fuel lines if you plan on running of ethenaol

 

Why would the car run like ***ty? How does the ethanol affect the performance?

 

DO a search in engine turbo drive train or just do a search there is a whole lot of info now
