Will older cars like my 1985 Gt have problems with E-10 fuel? They are not made to burn ethanol. Thought about getting a water separator filter, What do you all think about this fuel and future problems, They are going to increase ethanol to 15% soon, and eventually there will be no more pure gas to be had.

 

Im running with the E10 (or whatever comes out of the pump) with no issues. You should be fine for now. E15, idk yet.
