Just interested in opinions on using the E10 fuel in the Tuscon.

 

It won't hurt it. You will get lower fuel economy as E10 doesn't contain as much energy as regular gasoline without any ethanol added.

 

Using United Petroleums E10(95 octane).Have always used pulp95 mainly for cleaning additives.I am now an E10 convert.This fuel has transformed the 2.7lt Tuscon i have had and meticulously maintained for 2yrs.The car is now a lot more responsive(even more so than pulp98).Have read up on E10 stating increased fuel consumption but i am finding complete opposite to be true.
