I would suspect something is not right. I have had my 07 Limited since 11/06, now with 25+K on it. I have never seen below 22+ mpg on it, and usually it is well above 24+ mpg, with about 50/50 hwy/city driving. For the last 3,000 miles it has remained at 25.5 or better mpg. Longer trips (1000 + miles) easily are 28+ mpg at sustained 75mph or higher.
 
I use the shiftronic ability a lot in the mountains and cruise control whenever possible. Typically, I don't have to use A/C a lot here in Denver, but even during the summer, I still will see the car stay in the high 23 to low 24 mpg range. Despite my posting of taking the car above 140mph on one occasion, I would say I try for better mileage, but the power is always there if I need it, and I occasionally use it.
 
My last car was a 2002 Hyundai XG 350L and it got about 22.5 -23 mpg versus the 24-25 mpg I am normally seeing in my Azera over the last 16 months, as a comparison. Also, as I have posted before, I use synthetic oil and keep the tire pressure at 35 psi or higher (for a trip, I go to 38 psi).

If I were a bit lighter on my gas foot, I could easily better my current numbers, but it is what it is.
 
Sounds like you're doing pretty good though. Also, being up in Denver at that higher altitude, there's less resistance due to thinner air. Bring your Azzy down to sea level and your numbers will drop a bit more.
 
Like you...on long trips, i have witnessed very good numbers. Down to Florida and back, cruising at an average of about 75 mph, with 3 adults and 2 kids, loaded trunk and A/C...my FE was at about 26-27 mpg.

real mpg... the arithmetic way by dude60

OK folks, I now have 3700 miles on my 07 Limited/ultimate Azera. I just got back from a 1,112 mile trip from DFW to 3 different cities in 3 different directions here in Texas. Speeds 67-70, air on 50% of the time, It used 40 gallons even. This is not by the computer, it is actual miles and actual gallons of gas. 27.8 MPG ain't too shabby if you ask me. I believe I could squeeze 1 to 3 more mpg by driving 55 or 60 but I just can't choke down driving that slow.
 
I love this car, I am glad I bought it. Pearl white w/ black interior...looks good.

Actually, mpg is a lower at altitude. There is about a 10-14% drop in power due to less oxygen (check any drag strip records). So, you have push harder to get lower altitude performance. And, while I don't know if it makes any FE difference our gas is a lower octane than most of the country.

On trips of a couple of hours each way, I get 30.2 mpg!! Conditions :Level terrain using cruise control extensively with set speed at 65 mph. That means I am in the right lane most of the time. (Also provides escape route if an emergency occurs). Really don't want to use any of the available 8 air bags. Seems to make sense with gas at $3.75 and going higher. Next action to improve gas mileage when gas exceeds $4 per gallon will be be to slow to 55 MPH and stay in the right lane. Might have to drive a little longer to destination but it will be economical and safe.
 
Notice when my wife drives without cruise control and going between 65-70, MPG drops to about 29.5. We regularly get about 24 mpg on short trips around out town. Key to good MPG during around town driving slow and smooth acceleration.

Proof that it can be done! I crunched some numbers and found that a 15 mile freeway trip takes less than 2 minutes more at 65MPH vs 75MPH. It's also much more relaxing because you rarely have to change lanes - just sit back and enjoy the great stereo.
I haven't reset my trip computer for a year or so and it reads 21.5MPG for city/country/freeway mix. Pretty good, IMO, considering the power, weight, and size of the car.

I got up to 30MPG at 65 MPH going through the Smokey Mountains on I-40 a few months ago. AC on auto and cruise on.
  Most efficient speeds are around 45-60 MPH per what I read, assuming you are not stopping and starting or slowing down and accelerating.
   Using the shiftronic really eats up the gas.
  I average 26 MPG driving around a small town to the stores and so forth with a few trips of about 10 miles over two lane country roads.
  Consumer Reports (if you believe them) tested and discovered opening windows on interstate does not affect MPG in a Camry and using the AC might drop it one MPG.
   If really concerned about gas, drive the speed limit - it really pays off and may add 5 minutes to a 3 hour trip based on my experiences.

Bob;
 
We live in the country like you. Our roads are probably a little more flat in our area of TX. My wife and I drive 50 mph. on some of the farm to market roads and then 55 mph. on other highways. So far (with 3100 miles on the car) we are getting an average of 26.5 to 26.7 using the on-board computer and cruise with AC running. Today we made a trip to/from Plano, TX partly on US 75 and coming home by a different route with some stop and go traffic. The highway mileage (after a reset) was 31 to 33.8 mpg. After we did the stop and go plus the return home it dropped to 29.2 mpg.
 
Our altitude here is about 800-900 ft. There are mainly gentle rolling hills in our area and some flat stretches of highway. I increased the Azera's tire pressure to 32 instead of 30 and the ride is still just as comfortable. The cornering actually improved too. I am wondering if going to 34 lbs. pressure will be OK and not cause the center of the tire tread to wear out. Anyone have any experience with extended driving at 34 lbs. pressure in their tires?

Tire Pressures? [joezera] by snaglepus

I keep our tires at 37 PSI cold at all times, and with over 10K miles
on the car, the Michelin tires appear to be wearing evenly.
 
You will observe that the maximum tire pressure allowed by Michelin is 44 psi as
stated right on the sidewalls, but when I tried that, the ride became rather harsh.
 
With a steel belted tire, it is very hard to get the tread area to bow and to wear the centers.

Tire Pressures by carolinabob

I usually run mine at 32 and measure the wear every couple of months - appear to be wearing evenly. Not sure, but these tires seem to be more subject to change as temperatures change as with other cars I own/owned.
   I had a Camry with recommended PSI of 29 and discovered that 34 was the optimum wear PSI.
  At recommended pressures, I find the outside wears faster and many dealers use this as an excuse to do an alignment when it has nothing to do with alignment.
