Please report on your CX-7 mileage here.

Include your odometer reading, city/highway mix, driving style or anything else you think may help others compare their mpg with yours. Thanks!

    has anybody figured average gas mileage? early reports from
    the tests seem disappointing.
  • wmiiiwmiii Posts: 10
    I picked up my Icy Blue CX-7 with 12 miles on the odometer. I put about 120 miles on the car before filling up in order to check the mpg. I just filled it up for the first time shortly after the reserve light came on. It held 16.379 gallons, 285 miles, for an average of 17.40 mpg. This would be what I consider to be mostly city driving (i.e. stop & go interstate rush hour, city errands and a small amount of actual hiway. I am very pleased considering the Mazda-5 I replaced improved until the moment it was totaled in a rear end collision about three weeks ago. The 5 started at about 19.5 mpg and had increase to just under 24mpg combined driving. I am hopeful to ge the CX-7 numbers to around 20-22 combined in a few thousand miles. I drive very sedately so depending how you are with your right foot it could be better or worse. :)

    Picked up our Icy Blue GT FWD with sunroof/Bose May 28th
    Have used 5 tankfuls so far with a low of 17.4 with a
    70 city /30 hwy mix. Just returned from a drive up the California Coast. This car really likes the open road.

    22.7 MPG with 80 hwy/20 city going up.
    24.2 MPG with 85 hwy/15 city coming home.

    speed on highway from 60 to 78, no cruise control with a relaxed to medium pace.

    For a minute there I thought you meant you did 80 on the highway and then got stuck going 15 mph in town. :D

    I just picked up my GT AWD on Monday evening, 200 miles this week, and used 12.8 gallons for an average of 15.6 MPG mostly city and rural roads, no highway driving. All of the miles were under 50 MPH. I'll keep you posted. I almost cancelled my order from December due to a run around at the dealership, but I must say, "I am so glad that I didn't"!!
  • honakerhonaker Posts: 74
    I think I've gotten

    17.5
    17.25
    ??.?
    18.5

    So far. I'm a pretty aggressive driver. Driving is mixed city/interstate in the DC burbs.

    Just filled up after 813 miles on the odo. Last fill up @ 402 miles and since then used a total of 21.630 gallons for an average MPG of 19.09. I drive approx 40 miles daily to and from work in what I consider to be the tail end of rush hour traffic on the interstate. Considering the amount of traffic and the amount of stop and go driving I do these numbers would reflect about a 50%/50% driving mix. My first calculation showed 17.4 mpg several days ago. The fact that the car still has under 1000 miles I am confident that it should get into the mid 20's after a few more tanks. Tomorrow I will have my first chance the do a hiway trip and see what its like on the open road. :D

    Just filled up for the second time, did 266 miles on 13.7 gallons. About 45% highway, 120 of the miles. Getting better, and the milage is not much different from the 02 Millina S that I traded in! :)
  • russ_49russ_49 Posts: 54
    Getting better, 175.2 miles, 8.862 gallons. Had to stop and fill up tonight at a local station which has not raised their price today! WOW most of the stations here on the south shore of Boston just popped the price per gallon around 12 to 14 cents a gallon from the time I left for work this morning!
  • tomekktomekk Posts: 310
    My Millenia 01 S averages 23mpg in commuter 95/128 traffic in Boston... I'll get 27+ on the pike when keeping it under 75.
    MPG is main concern for me with the CX7 - too bad we can't get it with the 6 speed manual they sell in the UK.
    Car and Driver rated the CX7 at 14mpg - keep updating your real world posts, they are very helpful.

    Thanks!
    Tomek
    P.S. Where did you buy your CX7?
  • russ_49russ_49 Posts: 54
    I purchased it at Quirk in Quincy. I've been a repeat customer of theirs for a while now. Got it for 850 over dealer cost, and did slightly better than NADA on my trade which was an 02 milli S.
  • jayzunjayzun Posts: 1
    Are all of these estimates with premium fuel or using 87? Thanks in advance!
  • russ_49russ_49 Posts: 54
    My numbers are actuals and not estimates, and yes, it is using premium fuel 93 octane.
  • vinzvinz Posts: 1
    I'm planning to buy the CX-7 model by this coming fall and I'm concerened abouth the mpg and the requirement for a premium fuel. Would you know what would be the performance if I filled in a regular fuel on the CX-7?

    Thanks,

    Vinz
  • steverstever YooperlandPosts: 40,155
    I think the general rule of thumb is that you will lose about 5 to 10 hp using regular gas in a vehicle that requires premium. Performance for other cars that recommend premium generally lower their hp rating by 5 hp for running regular - that may not be a big enough difference for you to notice by the seat of your pants test. Who knows with the CX-7 though.

    If you are concerned about mpg, usually you get better mpg using premium in a car that requires it, and the fuel savings may not be enough to off-set the mpg loss if you put regular in the tank. Check out the What about fuel types & gas mileage? discussion for more on that angle.

    Just consumed 1st tank of gas for my new CX-7. 15.5 MPG (80% city and 20% highway) was the number I got. Though like the car(3 weeks so far), somehow disapppointed with its MPG. Hope it gets better after break-in period (600 miles?)
  • wmiiiwmiii Posts: 10
    Topped off the tank this morning with 1249 miles since last fill up @ 813 miles. Total of 436 miles on 21.648 gallons (includes a partial tank of 7.045 gallons). Looks like milage is getting better with each tank. This time Hiway/City mix would be closer to 60/40 and MPG was 20.14mpg. First tank 17.22mpg, second 19.00pmg. I am still confident given my driving style mid 20's will be about where it will end up. :)
  • I would recommend staying with the premium gas. You will lose performance, power and it will idle rough and it may harm the turbo engine most likely. I have an RX8 and it does horrible with less than premium gas. From another thread in another CX7 someone had good info. on this and how you really won't be saving $$. It has some kind of sensor too...go to Mazda forums....CX7.
  • russ_49russ_49 Posts: 54
    Just topped off, 232.4 miles 11.713 gallons 19.84 MPG, 886 miles on the oto, and loving every mile of it! I must say, this car definately has the WOW! factor wrapped up that's for sure! The only one in the area on the South Shore of Boston that I've seen, and it really turns the heads!!! This is my 6th mazda that I've owned and the best one yet!!! :shades:
  • wmiiiwmiii Posts: 10
    436 miles since last fill up. 18.721 gallons total fuel used. I drive about 40 miles daily in what would be considered about 50/50 mix. Using mid-grade and premium. Will be checking the milage using one then the other for a few tanks. Have total of 1685 miles on the odo. My 5th Mazda and by far the best. :)
  • russ_49russ_49 Posts: 54
    Another update, 283 miles, 14.47 gallons about 60/40 split city/highway for 19.56 MPG on premium only 1180 miles on the oto.
  • russ_49russ_49 Posts: 54
    251.1 miles 12.584 Gals 60/40 split city/highway, 19.96 MPG 1430 on the oto!!! :D

    I've had my CX-7 GT AWD since they hit the lot. Mine has had the following (using Premium... it's a turbo... you MUST use premium):

    21.2mpg
    20.8mpg
    21.1mpg

    All is commute/in-town driving...

    I am estatic over the mpg! Much better than the crappy 05 Jeep I had prior!
  • honakerhonaker Posts: 74
    Wow, that's the best I've seen reported for an AWD. Congrats!
  • marleybarrmarleybarr Posts: 334
    Have you noticed any so-called "turbo lag" on acceleration from a dead stop?
  • honakerhonaker Posts: 74
    I've never had a turbo before, but yes, there's a bit of a kick when it hits 2500 rpms.
  • nycdragonnycdragon Posts: 14
    2nd Gas Tank results in 15.75 MPG (0.25MPG improvement from previous 15.5 MPG) :confuse: 80/20 local/highway mix.
  • honakerhonaker Posts: 74
    We imagine the firt few fuel ups op will show increasing gas mileasge, and you adapt to the car, the car adapts to you. I've startling idling the engine after a trip to allow the how oils to drain from the turbo. I odn't know if it has an effect or not. When I hit a good cruising with level roads and not too tight traffic, i put it from auto into manual, let it just soak up 6th gear without worrying if id like 5th.

    Just for a guide, is there any sort of
    0-100rpms -- 1st gear
    1001 rpms - 2001 2md gear
    anything like this?
  • russ_49russ_49 Posts: 54
    Another update, 1713 on the oto, 283 miles, 13.842 gals 20.45 MPG! 45/55 city/highway!
  • vbbuiltvbbuilt Posts: 498
    I'm scratching my head here. Everyone KNOWS that the CX-7 is NOT fuel effecient and that it takes premium.

    If fuel efficiency is so important to you, then why on earth would you buy the CX-7?

    So why waste your time on this forum, bragging how much MPG you can tweek out of this vehicle? If you're worried about MPG, then take the CX-7 back to the dealer and get something else!

    I didn't buy the CX-7 because of MPG or lack of it. I bought it for a host of other factors. If MPG were an over-riding concern, I would have opted for a hybrid.

    Ok, I'm off my soap box and done with my rant.

    Vince. :shades:
