Real world MPG by odysseyhunter

Are there any Denali owners out there willing enough to share what there are getting in MPG. Here is my issue, my wife wants a Honda Odyssey. She won't even think of a Denali due to conception of poor mpg. The Odyssey in real world use, and depicted by owners here at the Insideline have indicated they are getting anywhere from 15-20mpg. If thats the case, and the Denali is getting the same, its a no brainer to go with the Denali. However I need this information on paper so I can prove to here beyone a resonable doubt that the Denali is a better way to go. I thank you.

There's a Honda Odyssey Owners: MPG-Real World Numbers discussion but there's not one for the Denali.
 
Unless there's interest in starting one, please toss out your city/highway mpg in here.

I don't have a Denali but a regular 5.7 Yukon XL. I have a K&N high performance air filter and run synthetic Mobil One. My wife drives mostly around town but either way trips or local - the average I get is about 15.5 period, no matter how I drive. Given the Denali is AWD, I would subtract about 1.0 - 1.5 MPG just to be safe. The Odyssey is a great van (I had one in 2000) but the Yukons are just more comfy inside and feel more truck like. I also like the fact that in the event of a collision, the Yukon will almost always turn out better than the other car. The vans just don't have enough nose and sheet metal between you and the other car. The good news is that the Yukons all run on regular gas vs. 93.

I've gotten anywhere between 16-17 mpg out of a tank of gas in my '04 DXL--this while travelling around 70 mph; one time I even managed to average 19.1 mpg over a 60+ mile stretch while traveling 65 mph--maybe a fluke/error but that's what the DIC reported. I might have been able to squeeze out another tenth or two mpg if I were rolling on the stock wheels/tires instead of the 20-lb heavier 22" shoes.
 
The Odyssey may very well get better fuel economy than the Denali--if even only by a slim margin--but obviously one wouldn't even consider a Denali unless power was a big factor. I mean, who would tell themselves, "I would consider getting a Denali even if it didn't have that 6-liter engine in it..."? Sounds like you definitely are attracted to the additional power the Denali makes over the Odyssey, fuel economy be darned. IMHO if you plan to do mostly highway driving, can control the urge to romp on the gas pedal for the most part, and don't plan to do a lot of long-distance heavy towing, the Denali should be good enough for you. OTOH--if there will be quite a city driving mixed in, then the Denali isn't it for you since I can definitely tell you that real-world city fuel economy sucks big time...rarely can I get 14 mpg (based on 90% surface-street driving) out of my DXL; low-13's are more the norm for me.

Thanks for the information!! I've determined that the DXL is the way to go. I want an 04' or 05' due to the fact that the 06' doesnt' have a "instant mpg" just a avg mpg. I was very dissapointed when I drove a new 06' and could get an instant reading. The DXL is just a logical choice for me. Thanks again.

You won't regret getting a DXL, reliability be darned (that being subjective, of course...depending on whether you really absolutely believe that foreign models/makes are more reliable than domestics)!
 
One bit of warning though--IIRC I believe it was (late?) '05 model-year that GM took away the instant fuel economy from their fullsize trucks/SUVs; not only that, they took away the "Personal" and "Business" trip meters (not that big of a loss since I believe they now just display "A" and "B")...and the worse thing of all (as far as convenience is concerned)--the Driver 1/Driver 2 memorized seat/mirror/radio settings recall feature via keyfob remote was also taken away for '05-'06...you can still set/recall memory settings, but ONLY via the recall buttons on the door panel.

I can't remember if I posted this before, but I had an idea last year to get some foam pipe insulation and stick it to the bottom of my garage door. That keeps the tailgate from getting scratched when you open it inside the garage. Thought maybe somebody else could benefit from that.
 
I can open the rear glass without hitting anything, even with the garage door closed, but the tailgate is too tall.
 
Have a good weekend, everyone. It might snow in Dallas today, I think I'll go find an empty parking lot and play with Stabilitrak and ABS.

No way does a Denali get 15 to 19 mpg, no one makes a 5.7 liter engine with that fuel economy in the real world. You cannot use the cars computer to determine your mpg, you have to do it the old fashioned way. Run through a tank of gas fill it up and divde the miles driven by the # of gallons just entered. I have a Yukon XL and have never gotten more than 13 mpg city or over the road. On top of everything else these cars have terrible service records, run through brakes and tires and are not safer than a Honda Oddysey. In fact these larger trucks are less safe because people feel they have more protection and drive more hazardously. Obviously only thinking about their safety and not the guy they just ran into. Good luck.

Tire change by ahightower

Well I learned the value of OnStar, without even using it. I had my first flat tire. Not a blow out, just a slow leak due to a big nail.
 
Man, what a hassle to change the tire. I'm sure it will be easier and faster the next time, but the first run through was a challenge. That little jack sure moves slowly doesn't it? Like twenty turns to move it one inch. And at first, the spare tire didn't want to come all the way down, there is some sort of "catch". The manual said to try cranking it back up again until you hear two clicks. If that doesn't work, you have to balance the jack on the tire blocks and raise it up to release some lock or something. Luckily, it came down on its own eventually. Then once it was down, it took me a while to figure out how to turn that bracket just right so it would fit through the wheel.
 
I've learned my lesson - practice changing the tire on a new car in your free time so it's not a hassle and a completely new experience when you're in a real hurry. I really have been meaning to, but it's been a busy 7 months...
 
So I am definitely going to renew OnStar when it comes due. I hate to think of my wife trying to change a tire on her own. Much more laborious and time consuming than doing a donut on a regular car. She watched me do it and understands how it works, but it takes a long time. I hate to think of her working on the side of a busy road for so long, or in a parking lot attracting the attention of strange men. And truck tires are heavy (surprise surprise)! It was hard even for me to lift the spare into place, and then to get the flat up inside the back. If she's alone, I'd rather she just call for roadside assistance. Heck, I'd call OnStar myself if it was raining. I hate to look like a wimp, but that job takes a long time. You're going to get soaked, and you absolutely have to get down on the ground to place the jack and get the spare out.
 
Overall, I am impressed with the new vehicle. This is my first large SUV. The storage system for the spare is a neat design. It's a full size spare, and you can store the flat in the same place after changing. It has a lock that prevents other people from stealing the spare tire. And the TPMS is great. I had the kids loaded up and was ready to drive off when it warned me that I was low, down to 17 psi. I'm glad this is becoming a standard feature on new vehicles.

I've got a 2004 Yukon XL Denali and am having to have the transmission relpaced at 43k. Dropped the car off at the dealership and within 5 min. got a call stating the problem and that they had contacted GM and GM would cover the repair less a $500 deductible. I don't even have an extended warrantiy. Talked to a fellow at the dealership 2 mo. ago who had a '04 Envoy who had has his tranny replaced at 15k and was having problems again at 30k.
Sounds like GM knows there is a problem but doesn't want to announce a full scale recall.
