I also live in the Lake Tahoe area, at 6000 ft elevation. In my previous '05 Denali, it got 12 mpg in the same environment and usage. I've been pretty impressed with the '07 6.2 so far.
The 3rd tank is having 16.2 mpg so far. More high way than local roads.
5200 miles and my YTD MPG is 16.8 with 55% highway and 45%
city mixed driving.
13 mpg city
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!
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.
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).
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.
I have the Denali XL. The touring is not as noisy. Love the sound.
Would have been an o.k. SUV when gas was 35 cents a gallon. But that will never happen in this world.
i tend to get a bit heavy on takeoffs....even though punching it at a stop wont even get a chirp....maybe my tires will last a bit longer .. i have about 1000 miles sofar i like it. real nice interior quiet ride comfortable chairs the exhaust on the denali are huge compared to the other sierras......denali has a rear exit tail pipe ....l like the sound better.
