Yes my mileage sucks I now have 5,000 miles on an AWD and still I am only getting 12 mpg in city and 15.5 mpg on the highway at 65 mph. I drove up from Houston, TX to St. John, NB at the beginning of the year. On the trip up using regular gas I got 13.6 pulling a little 4x6 trailer and 14.7 is the best using premium gas on nice freeways. The weather was great and the temperature did not seem to affect the mileage. I do have the dealer checking with Mazda and will be bring the SUV in for service to have the computer checked.

U know you're not supposed to be using premium gas though right?

16.5 mpg, 90/10 city/hwy, nothing over 60 mph. Not too bad. Our 04 Pilot was always 18-19. I would hope with the 6spd, it should be able to accomplish that.

Auto Climate Control affecting MPG??? by vinsuz

I am still on my first tank of gas (just bought an '08 GT AWD this past Saturday) and have been watching the needle go down faster than Paris Hilton at a movie premier! I've put about 120 miles on the odometer and am down to a half tank! Then I turned off the Auto Climate Control and after a day (about 30 miles or so), I am still hovering around a half tank. Auto Climate Control appears to keep the A/C compressor running (the A/C light stays lit), and we all know how A/C affects mileage. When I took delivery, my salesman said the A/C stays on in Auto Climate Control mode in order to more effectively defrost the interior windows when necessary, but if it is going to have such a negative impact on my mileage, I'll adjust the controls myself. I really don't like the thought of not being able to use the Auto Climate Control feature since I've had it in my previous three cars and have become quite accustom to it.
 
I've seen a wide range of mileage reports in this thread, so I wonder if people would also add whether or not they have and/or use the Auto Climate Control feature.

2nd tank on 2008 by kj123

My first tank yielded 18.1mpg, second was really close at 17.9mpg. Mostly city driving on regular gas with a FWD Touring. I can't complain about it since regular gas is recommended and it is above average for this type of vehicle.

I noticed that with the A/C off the windows tend to fog very easily so I leave mine on. You can reduce compressor cycling, however, by turning off the rear unit.

Just completed a 1,000 trip in a 08 GT AWD and average mileage was 18+ with 90% interstate at 75 mph with some mixed city. HVAC was on entire trip with AC light illuminated (don't think the compressor was needed as it was 30 degrees most of the trip. I don't think I ever saw 21 but it was far better than previous 14-15 in town. I feel much better, as it is no worse than the Jeep liberty that it replaced which got 16 no matter what we did.

The problem with the MPG by jchcraig

There is a problem with the MPG and it is or could be the TCS, which is being engaged when not needed creating drag. Turn off the TCS and a light comes on saiding it is off however it re-engages as soon as you take off. It should only re-engage if it detects slippage, therefore something is wrong if the light goes off showing that it has re-engaged. I have also noticed that I am getting brake noise reflecting that the system must be using the brakes to create drag causing the bad GPM. Also this is a hazard as I was pulling out of a drive way in the snow and the system has a delayed action which had brought the car to a stop and I was frantically pushing the gas pedal to get out of the on coming traffic. This is a very dangerous car and I have told Mazda this.

I think you should do a little reading about the TCS before you make such elaborate claims.

My first tank MPG was 16.5mpg with 50/50 city/highway. The highway portion is mixed with daily commute congestion (30-40mph for 50% of the highway).
This is slightly better than my BMW 540iA (V8 4.4L), which did 16mpg on the same route. Of course, this is no where near what my Prius does, 44mpg.
Same route, same speed, same driving style.
 
I am happy with the CX-9. This vehicle really shows what Mazda can do if they really try. Bravo!
