to be honest, no, I really dont, I did check it out when I first got it, but cant remember what the number was, lol, I always keep that computer thing on the "range" but remember, from my understanding, the gas out here (Denver) is different than most, we have Oxygenated fuel, I dont know what it is or what that means, lol a few people have told me that
Oh, and I do drive mine like a V8
I remember looking at the V8s and a couple sales reps said "there isnt much difference in the mileage to worry about, if you want a V8, get it, we have both, the V6 and the V8"
I was going to get the V8 regaurdless, lol
