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
#15 of 25 GMC Yukon/Yukon Denali: MPG - Real World Numbers by rsht Dec 30, 2006 (5:15 am)
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.
#16 of 25 Should I get the 6.0 or 5.3 engine for my XL by donxl Feb 21, 2007 (2:14 pm)
Can anyone tell me the difference in gas mileage between the two?
#17 of 25 07 Yukon SLT 4x4 by youngmoney Feb 22, 2007 (8:29 pm)
I have an 07 Yukon 4x4, about 15k miles, and I get 14 mpg doing 80% highway, and I am pretty heavy on the gas pedal so I think that is pretty good. It looks really good compared to the 12.7 mpg I get on that 210hp Commander V6.

#20 of 25 07 Denali XL--Gas mileage increase??? by schu300 May 15, 2008 (9:26 am)
Just curious for those of you who have these beasts of a vehicle (Denali XL or Denali or even Tahoe/Yukon) what have you guys done modifications wise to get better gas mileage and has it paid off?

Replying to: schu300 (May 15, 2008 9:26 am) Below is just my personal experiences through my previous vehicles: 1. Cold Air Intake modification - not at all cost effective, so not done on my Denali. 2. Using Synthetic oil mostly for better protection - on all my past cars and my Denali today (Engine and Axles only). 3. Engine Computer mod - not done on my Denali (enough power for me as is). 4. Maintain proper Tire pressure (weekly basis) 5. Try not to drive over 75mph (I observed at ~68mph with best MPG) 6. Try not to drive with a heavy right-foot; but that will defeat the purpose of buying the Denali with the 6.2 V8... Doh! 7. Keep junk out of the SUV as possible. 8. I still think brand name gasoline (BP & Shell) is better. just my opinion. 9. keep up with regular maintenance (You take care of it and it will take care of you most of the time).

Replying to: rsht (May 16, 2008 6:04 am) Items 2,4,5,6,7,8 and 9 are all done on a regular basis.....   I am not interested in item 3.......but have thought seriously about item 1....   I fuel up about once every 7 days, doing mostly city and the occassional highway (65mph) 10 mile trip.........it never fails, my MPG on my computer is always 12.4-12.7......   If I am on an all highway road trip..I sit at 15MPG by time the tank is running low.   Im just curious, if maybe the cold air intake would make a slight/major difference if anything at all.

Replying to: schu300 (May 16, 2008 9:48 am) Yes it can. I installed the cool air intake along with the performance exhaust (GMC dealer installed) and I get 17 street 20 hwy ( 55 Mph). Make sure u get the touring exhaust, not the performance. When I get up to 70 I get a solid 18 Miles per gal. I have the Denali XL. The touring is not as noisy. Love the sound.   D-Burbs
