I'm not holding my breath that it will continue to be so high....but I'm sure hoping!!

15 MPG and 22 MPG

Well I filled before a long trip and I report 15 MPG.....approx. 30% highway

Went on a long trip in the HILLS of upstate NY AVG speed 70MPH and got 22MPG (99% highway)

I wonder what Flat Highways at 55MPH does for mileage? anyone from out west?

ALL WHEEL DRIVE TOO!

I doubt you'll get anyone to drive 55mph just to find the milage.

Update, I just got 17.440 on my last tank. I stopped using the remote start and went up from 14.40 so I guess it was my own fault. Now I have the honor of having the check engine light on... I will be dealing with that now, tempted to just ignore it till I need to go in for service on a maint. schedule.

It probably will go off after a few days if it is just your gas cap. Just be sure it's tight. If she's running fine than it's probably just that.

I'm averaging just under 22 MPG (about 90% highway) after 3500 miles.

For majority hwy driving that sounds about right.

I've had my car about three weeks and here are my results:

First tank: 17.8 MPG (278.9 mi)
Second tank: 19.8 MPG (312.5 mi)

I think the key to good gas mileage is not popping the turbo. The mileage should continue to improve for several thousand miles, so I'm very pleased with it so far. I know other small SUV owners who are getting much worse at the beginning of their vehicle's life.

3300 miles on the car. First oil change since purchace with 800 miles on it. 6 quarts of Mobil1 full synthetic, replaced oil filter cartridge. First fill up 230 miles later with 9.8 gallons, 23 MPG basically, with Shell 93 octane. driving 50/50 city and freeway,

and stickers are like 10 horsepower!! I was shocked at fillup, trust me. Hope it remains up there, too.

Sweet.

Another fill up of 93 octane in the CX-7 AWD, 50-60% highway 18.05 MPG.

Drive the crap out of it this tank. You'll get crappy milage but it will help to loosen the motor up. Also it's a hoot to do.

Hi All,
Haven't posted for a while but now we're up to 3500 miles. We have a GT AWD and we are still getting around 16mpg with aprox 2/3 highway driving! We do drive spiritedly.

Has anyone actually brought this up to Mazda? I have heard of other manufacturers offering ECU flashes to cure various problems in this area.

Thanks.

 

[G-Papi]

I doubt whether Mazda cares. They know what their cars do. And besides, they sell.

If you drive spiritedly then it's to be expected. Hey both my 5 and 3 are normally aspirated engines and they also guzzle gas when I drive spiritedly (highway or city). I've seen my 3 and 5 drop to 20mpg in mixed driving, but have also seen them get 30+ when I drive at 65 on the hwy.

These fuel economy discussions are getting old. Listen, you got an SUV with a turbocharged engine that makes a lot of low-end torque. What do you expect? I'll say it again, if you want a car that is consistently fuel efficient then get a Honda that makes all it's power at 6 million RPM. There's a reason why Honda's are more fuel efficient, it's because most people don't rev the hell out of them. They stay in the low RPM region that does not create a lot of power and therfore does not consume much gas.

G-Papi, it maybe a side-effect of e-discussion, but it sounds like you are constantly accusing Mazda about "not caring"- whether it be for fuel economy or crash worthiness (seats). Am I wrong or do you have a bone to pick?

I remember being shocked when gas jumped-up to 45 per gallon... I was too-young to drive, but I remember it. I think the lowest I recall is 25 p/g.

And back then, one guy filled the tank and two other guys came-out... one checked fluids and the other cleaned the glass.

I'm not even 40yo and I remember that.

I wouldn't have guessed gas costing OVER 10x that amount.

In High School... $8 filled my tank.
