Mile Per Gallon!!!!

Prescott to East side of Phoenix (120 miles interstate/freeway)
Phoenix to Lake Havasu with cargo (260 miles, half interstate/freeway, half winding highway)

22mpg

Havasu to Prescott. (200 miles, 5k steady 80mph climb)

Waiting to fill up again.

I think you have one of the leanest CX9s around. I'm jealous!
 
My '08 is still getting a steady 20-22mpg, calculated with a calculator after each fill-up. Maybe it's Arizona....or good gas?
 
I avoid the expensive gas like Shell and Chevron. Since those have more filler and less actually combustible material, maybe that makes a difference.

They can claim cleaning power all they want, but it's really just a legal way to water down the gas to increase profit. The best way to keep an engine clean is efficient combustion from pure gasoline and normal maintenance (plugs, filters, etc)

Not true. Gas is gas. All gas has detergents. The amount of detergents put in any gas is so small to be unmeasurable with regards to specific heat content. I just use whatever is cheapest and convenient.
 
By proportion, a 3.5L engine will consume 0.55% less gas than a 3.7L. That translates to about 0.99mpg ~ 1mpg. Therefore, a 2007 has an advantage of 1mpg over 2008/9 models, even if EPA rated them the same. (note: Highlander and Pilot both have 3.5L engines)

As the links indicated, all brand of gas comes from the same refineries. The gas tankers get the gas from refineries and add additives to the bulk gas and send to the gas stations. The condition of storage tanks of gas stations probably matters even more than the brand of gas. Some stations are old and outdated. There may be lots of sludge at the bottom of the tanks.

Anyway, my friend who is a auto-mechanic recommends me to add a bottom of STP gas treatment on even two/three fill-ups. ($1 each) The effect is probably better than buying Shell over no-name brand gas. If Shell charges you 0.05c more per gallon, that is $1 per fill-up (asuming 20 gallons) more than the no-name brand.

I personally believe in the theory of carbon deposits build-up on the valves because I saw it myself on my old student car, a 1985 Honda Accord.
 
I seem to have problems with carbon deposits myself. Both of my vehicles needed the injectors cleaned at about 60000 miles as per the dealer mechanic. How often are the injectors supposed to be cleaned?
 
I got 20 mpg with my last fill up in mainly suburban driving and 1,650 miles on the car. I think the warmer weather is helping as I do a lot of short distance driving.
 
I just returned from a 800 mile trip to Arizona from California. Whoopee, an average of 19.5 mpg all highway with cruse control.

I even looked for some of that special holly water that the Arizona people claim gets 22 mpg, but couldn't fine it.

PS. Its a tank, just admit it and pay the price. It rides and handles great.

Cruise control set to what? 90?

I got 22-23 mpg (AWD) on my trip to Disney from DC. I even had the A/C on most of the way home because it was 80 degrees outside. I was I95 most of the way so speed varied from 60-80.
 
It is very easy to get 20-22mpg with CX9 on highway as long as you have steady feet on the gas pedals. On city stop-n-go, however, 2007 model might have some advantage (being 3.5L vs 3.7L). Plus, FWD will save some gas on hauling the extra 200lb AWD hardware and spinning them for nothing. 18" wheel/tires help a bit also (over 20"). For me, 3mile round trip stop-n-go with my AWD 2008 CX9, I will probably get 15mpg.

Stop and go means nothing, except you have a heavy car. My wifes 2005 Acura TL gets 29mpg on the freeway doing 75mph and gets 13mpg when she is driving my girls locally. The CX-9 does about the same around town and prolly gets 20-22 on the freeway(havent checked it yet w/o a trailer). The CX-9 weighs 4400 lbs, in stop and go its simple physics. My buddys 2007 MDX is slighly worse
 
On our first short road trip with the CX-9 we got 22.6 miles per gallon. Went 366 miles, 40 of which were city and the rest were flat interstate miles going 70 mph. I had hoped to get 24, but maybe the city miles brought it down.
 
Yes, mine is Galaxy Grey too. I'm glad I got the Sport, but I got the black interior which shows all the dirt. That was my only mistake!
 
Yes, I like the black seats but the black carpet shows all the dirt. Oh well, I guess it make you vacuum more often and keep it clean. We were offered a tourning with a sunroof for $2k more, but my daughter hates leather for some reason and I think the cloth is more comfortable too.
 
I thought the multi tone sand leather was very nice too. We tend to keep our cars for a long time. We have a 10 year old Lexus with beige leather and after 10 years the drivers seat which gets all the use looks worse than a cloth seat would. I think if you take care of the seats, cloth looks better longer. We had a 1988 Honda LXi with a burgandyish/brown interior and when we finally sold it at 15 years old, the interior still looked great.
 
Mpg

Well this is my 2 cent worth!

We took the 08 AWD CX9 on a 2 week 2000 mile east coast trip.
Since we stopped often, for the kids, we refueled every 300 miles and I topped the car off to make all MPG calculations accurate.
Our best MPG on 300 miles was 25MPG (95% Highway) at a constant 70 MPH on flat terrain in Ohio. The next 300 Miles had some hills (50% Highway, 20% rural and 30% City traffic). MPG dropped down to 21.
Mountain driving was impressive. This car really bites in the steep hills! MPG 22 with 70% Highway, 20% rural and 10% city.
The worst was Washington. Although 50% was Highway and 50% of the 300 Miles were in the city the MPG dropped to 18. This was of course due to the stop and go traffic. The last 300 were a combination of Mountains/ Hills/ and flat terrain, 99% Highway and a 23 MPG fuel consumption.

So what did I think of the car.
When my wife bought it and I started reading the forum, I was not sure we had made the right decision. I didn't like the MPG consumption (70% city gave us 15-18MPG).
Now that I spent 2 weeks with it, I am starting to like the car more and more.
It is a very comfortable and roomy car. After an 8 hour day in the car I wasn't tired at all. The GT version we have has all the goodies. The one I like the most is BLISS. An awesome feature that works great. I even start to like the NAV system. It is not the best but when you know how to use it, it is not really that bad and has neat features.

We had a great 2 weeks and part of it was thanks to our CX-9. An average of 21,8 MPG on a 2000 mile trip is not too bad (It isn't great but for such a heavy car not bad at all). I can't wait to go on our next road trip :)
