I just want to throw out there that when I had my Jeep Grand Cherokee it got better gas milage than its I6 twins on the highway. I attribute this to the V8 pulling the weight better on the highway. The thing is though at those times I was being very easy on the gas. It didn't take much of a lead foot to kill those numbers where as the I6 engines were pretty steady on their mpgs. Off road the I6 did a ton better. When I hear the Vette guys and stang guys talking about how good their milage is I am sure they are babing their cars to get that. Around town they suck gas. If they drive like me good luck seeing good milage in any situation.
