Mazda6 Real World MPG



  • I have 09 Mazda 6 s Touring with 1100 miles on it so far. I drive 80% hwy 20% city and the INFO Button says I'm getting 19 MPG. My engine is still breaking in so by the time i get my first oil change, MPG should be in the 20s

    You will get there. Don't worry.

    In days were gas is on everyone's mind, we tend to watch our fuel economy a bit more then normal. A few of my V6 customers are getting an average of 22-23mpg. One stated he got as high as 27 on the highway. I was rather shocked by that.
  • dumb question, but have you reset that at all during those 1000 miles, between fillups? Seems kind of low to me.
  • No! I thought it resets by its self. So after every fill up you have to reset? How do you reset it?
  • Wuts the purpose of Resting the info button?
  • Nothing to do with MPG!
    Computers on all cars not accurate!
    Need to fill the car drive till it's empty & refill.
    Take total miles & devide by gallons of gas.
    Only way to be accurate otherwise your just guessing!

    Hey Barry,

    Check out my post #98 on this forum. Albeit it was not many miles, but I found the computer on the 6 to be pretty close to calculating mileage the manual way.

    I have read that some car's mpg computers are up to 3 mpg off though.
  • hold down the info button till it beeps, that resets the Average MPG.

    For me, it's been pretty spot on for accuracy compared with my calculations.
  • At least if not more!
  • I have a V6 auto MAZDA6 Sports Sedan GS ( 14,500 now ). Worst mpg was 18 in almost all stop and go, when the car had just a 1000 miles on it. Over the past two years I have gotten about 21 mpg in a 70/30 mix of suburban and highway driving. 23 mpg tops when I do 60/40, and I'm not driving aggressively,

    The best mpg so far, was on a recent 175 trip on rural and interstate highways, 60 mph average - 28.3 mpg. I'm happy.

    one day, I talked to two other owners at the dealership who have v6s, and one said 29 highway, the other said 30. If I didn't have about 125 of those 175 miles on the rural highway with occasional stop and go traffic, stop signs/stop lights thru the small towns, I believe 30 mpg on the Interstate is very achievable.

    I have a basic 2007 I4 with a 5 speed. I do about 90% of my driving on the highway. I have carefully tracked my mileage (have put over 40000 miles on it in the past year). The worst mileage I have gotten has been 32. The best (two different tanks) has been 39. During the Summer it averages 36 to 37. During the Winter closer to 33 to 34. I find it does a fair bit better at 70 miles per hour as opposed to 75. (Our speed limit here in CO) I am not sure why my numbers are so much better than other postings on this site.

    Does anyone have some real world numbers on what you're getting with the I4 auto?

    I have a 2009 Mazda 6I Touring with Convenience Package (Automatic Tranny). I do 100% city driving, my car has about 1700 miles on it and I've been getting about 13.5 to 14 mpg. In all honesty, I think that something is wrong with my car. Can anyone confirm this? Will my mileage get any better? Should I bring it to the dealer to get checked out?

    I would take a little road trip and see if you can tell what hwy mileage is. City driving is so different for everyone what with the stoplights, congestion etc. If you live in a very congested area that could be the reason. The EPA doesn't take the worse case when it estimates city mpg.

    I have a 2007 6i 5-door, 4 cyl w/5 speed auto. I live in Detroit. My driving is a city/highway mix. I'm getting between 22-24 city and 28-30 highway. a little less in winter. I'm very happy with the car.
    I hope this helps. :shades:

    I have the same thing except mine is a 4dr and my mileage results after 28k miles is similar to yours. Most long trips I can get 32-33 mpg. I usually drive 5 over the speed limit. However, when I drive in Michigan where the speed limits are 70 and the potholes are large I tend to drive pretty much at the speed limit. :)
  • 2003 6s, 5 speed, 89000 miles

    worst tank 20.6
    best tank 25.9
    lifetime everage 22.3

    Considering the EPA figures were 18/26 and the fact that I tend to drive this car kind of hard, I'm happy with it. Note: this car has an AEM cold air intake and Racing Beat exhaust (neither one seemed to affect the mpg either way).

    Just to respond. I have a 2007 6i 5-door Touring w/ the 5 speed auto, with 52,000 miles. It's my second 6. The first got stolen and totaled. Overall all driving in mixed city and some freeway in the Detroit area, I get between 24-25 mpg weekly in summer and 22-24 mpg weekly in winter. On long trips, I get 28-30 mpg at a consistant 70-80 mph. I'm very happy given this a mid-size car with the automatic.Also, I've had no problems at all with the car. It's very reliable.
    I wish the current 6 model in the US still came in a 5-door version.
    Thanks, :shades:
