I use to run my 73 Ford 460 CID Thunderchicken to work. Nine miles one way..I had to run it on 93 Octane or else it sounded like 8 midgets with hammers inside the motor.
Best I could do was 9.5 MPG.....So my 07 H3 is like a Solar powered rig to me.
Gas Milage...Who cares..?? I'm haven fun just talken to the OnStar Beeyoch...
