03 QC 4.7 with 105k miles. I get around 15.5 city, 20,21 highway doing speed limit. About 18 doing around 80. I am in the 14's when towing, which is a lot better than the single digits I was seeing while stock, weight is over 5000 lbs. Going to put an efan on, hopefully it gets a little better.
Well I just filled it up and ran the numbers, boy was I dissapointed. This was all city driving, I live 5 miles from work, but I only got 13.5 miles per gallon. I went with the computer milage thing over head, next time I'm going to write down from the odmeter and compare to the digital one over head
strictly in town i get about 11mpg, 12.5 mixed and just under 17 on the highway at about 65mph. it's all stock and i baby it trying to get the best mpg possible. just ordered a superchips 3865 today so hopefully that'll help.
