Mile Per Gallon!!!!

Just wanted to add our milage from our first trip in our used 2008 GT AWD. The trip was about 250 miles and nearly 100% highway driving, and the milage calculated out to 22.5 MPG. Seems to be pretty decent to me for such a large car with AWD and decent power. Now we'll use it for a week or two for city driving and see how that rates.
 
We keep track of our mileage with every fill up. City driving is quite consistent around the 15 mpg mark. Highway mileage is is the 21's and sometimes in the high 21's (like 21.8 for example). On the highway, I'm usually running 70 to 75 mph and use cruise control maybe 50% of the time. I think that mileage is pretty good for a large vehicle.

As others have said, there are so many things that can affect the numbers. Wind, heavy traffic, a lot of stop and go, excessive idling can all hurt mileage along with driving style. And it's amazing how much a good tail wind can help gas mileage!
 
My family and I just did a round trip to Portland, Or from Bellingham, WA (524 miles). Carry a Thule Cargo box, the 5 of us and 2 small dogs. We average 22.2mpg, of course I had cruise set at about 65- 68mph. But hey I had to let loose every now adn again to here the engine stir up.
 
Well this all sucks!!! Just got my 2007 AWD Touring, and after 2 fill ups averaging 10mpg...

"CX9 SportOwner" there must be something in your Arizona air or something...
 
I average 10mpg when I
- start CX9
- drive my kid to school 2 miles away - stops/lights along the way
- come back
- check ScanGuageII-X -> 10mpg!!!

Short trips are mileage killer even for Prius.
My wife gets about 35mpg (instead of 50mpg as Toyota claims) with her Prius on the same routines.
 
a few years later, and this thread is still showing a wide range of mileage!
I posted many times a year or 2 ago on this thread, and nothing has changed now that I have 27,000 miles on my AWD CX-9. I drive mostly around town, lots of short trips, and I still get around 12-15 mpg. From a full tank, the light often goes on at only 240 miles.
On long trips I can almost get 20 if I drive slow. I think my highway miles are worse than some others because for long trips I have a lot of weight in the car, and I also have AWD.

That's about the same mileage I average. I rarely get over 240 miles on a tank with mostly city driving. I hit 15.6 the other day but that was because I had more highway miles. This thing loves to guzzle fuel, but it doesn't help that I'm a rather spirited driver even in a 4600 pound behemoth.
 
WOW! I constantly average between 17-19 combined city/hwy and my commute to work is only 7 miles one way. 2007 Touring FWD
 
its amazing to see the difference between the FWD and the AWD mileage. all that rolling resistance of the AWD sure does kill the mileage.

i have only seen less than 300 miles per tank a few times. i think the fuel mileage in this large of a vehicle (and with this much power) is great.

YUP! mine has given me anywhere between 305-350 miles per tank, but constantly 305-325 miles. Usually filling up with 16-18 gallons.
 
Lead foot plus extra weight = crappy gas mileage apparently. I've yet to see the trip computer hit 300 miles. Apparently I need to slow down.
 
I'm a lead foot myself and I have the many speeding tickets to prove it...but I just filled up this morning...19.1 gallons with my trip meter reading 345.3 miles...18MPG...pretty consistent.
 
I see 14-16 on my usual commute which is about 5 miles of in town and go and 8 miles highway. It usually takes a 100 mile plus trip of mostly highway driving to have the average for that tank go over 16 MPG. The best I have ever acheived was 21 on an all highway drive but I was still doing 70+ MPH with 2 adults/2 small kids and a few suitcases. I'm at about 15,000 miles on the odometer now and have been using synthetic since 8000 miles.
 
I have an '07 GT AWD with a scangauge and nearly 48k miles. My mileage can vary quite a bit. It can be in the low teens to as high as 19.5. I hit 21 mpg once on a long trip. Just did a 600 mile weekend trip and averaged in the high teens. I thought there was something wrong with the car when we first bought it because of the lower than expected mileage, but realized that my heavy foot was jockying around a heavy car. The scangauge helps and keeps my wife from running out of gas!

hard to believe Mazda always claimed that their customers don't want trip computers isn't it. Now the new CX-9s have them finally.
I have been posting on this particular thread for a few years now, and recently for the first time I finally got 20.3 mpg on a single tank. After 30,000 miles of never hitting 20 mpg. The difference was that on this trip I never hit 80mph once. I kept my cruise at 75 for around 400 miles. I guess if I kept it at 65 I could get 21mpg, but that just wouldn't be worth the extra 1/2 hour of lost time. After almost 3 years I have finally come to terms with my 16mpg average SUV.
