| 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. | |

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) 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) 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)  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 |

My '08 gives 10 mpg local and 16 on the open road. Yes, it's a thirsty pig. Would have been an o.k. SUV when gas was 35 cents a gallon. But that will never happen in this world. |

Replying to: naligirl (Jul 30, 2006 6:27 pm) 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. |
