#11 of 25 Yukon MPG by dmyer3 Sep 28, 2006 (8:34 am)
Last week I returned home from Charlotte, N.C., a distance of 457 miles. From the hotel parking lot in Charlotte to my driveway my average was 19.2 mpg. I am happy with this considering that my Yukon had only 4200 miles on it when I left the hotel and much of I-77 through Virginia and West Virginia is mountainous. I drove about 3 mph over the speed limits which put me at 68-73 mph. The AC was on 100% of the time and I used only 87 octane gas. My Yukon has the 5.3 engine and 3.73 gear ratio. Oh, I did have Amsoil synthetic, 5w-30 in the crankcase.

Replying to: hucktwain (Sep 26, 2006 6:45 pm) Hi, I just picked up my '07 Denali lastnight and I was browsing everyones feedback regarding MPG. I noticed mine said 9.6 the whole time i was driving it home. It also said I had used up 10 Gallons of gas. This has to be wrong because I just picked up the truck and it had a full tank. The gas gauge is on "F". Someone mentioned resetting their fuel economy. Is this what I need to do or is something wrong? How do you reset it? Thanks!

Replying to: double_down (Nov 09, 2006 4:21 pm) Pull up your "average fuel economy" stat in your view area and push the check mark. That will reset it. Mine came off of the lot with 27 miles on it and an average of 6.4 MPG. My wife drove another 150 miles on it and had an average of 11.7 MPG. I have since reset it and will see...from what I've read, I don't expect to get a mixed MPG result much better than 14, but that's the price we pay for playing with this kind of power

I got my 07 Yukon Denali about 3 weeks ago... We have taken it on our winter vacation as well as local to/from office. The following is my MPG report: 6.2 V-8 with original factory engine oil, cold tire pressure at 30 psi at each tire (or at 33-34 psi according to the gauge displayed when hot)--- Local (1 Full Tank, myself only) with Stop-N-Go traffic, at max 40 mph with AC On ~50% of the time => 13.6MPG Highway (1 Full Tank, myself and 4 passengers), at ~67 mph (Due to break-in period, speed vary between 60 mph to 75 mph) with AC On 100% of the time => 20.8MPG Averaged at 17.2 MPG.
