You also need to upgrade the fuel system components
the AFR for e85 is lower ie more less air and more fuel required.
cheaper per litre but not per 100km.

either way the car owners manual should say what fuel to use.
i would never by regular unleaded/91RON or what ever it is, i question using that stuff in my lawnmower.
