    Second tank, mostly city driving, for my 2006 Mazda 6, with 4 cylinders: 24.65 mpg.

    My car, purchased 1/6/05, is driven primarily short distances, and gets 16-17 MPG. My best mileage was from Angel Fire, NM, back to Denver the April after I had bought the car: 28 MPG. About 80 % of this was on I-25, where the speed limit is mostly 75, and I set my cruise on 82. It is stupid to speed on Interstates because that is where most speed trapts are in Colorado.
    It is rated at 20/27 with the 6 spd AT. If you read Consumer Reports you will read that City mileage figures from the EPA are inflated about 30 %.

    I think that a lot of people round up their mileage just to impress. I use a calculator. :) I guess if my city driving included freeways where traffic is moving well my MPG could improve to 20 in the City, but I am retired, love cars, and have been in ill health the last year, so haven't really put many miles on it.
  • I use my '04 6i MTX for commuting 80 mpday; sometimes down rural roads, sometimes down the interstate, depending on the season and weather. Used this way, this thing gets 29-31 mpg; let's say 30 average. Like many others, my commuting costs have risen since the price of fuel skyrocketed. I was happy with the mileage in '04. Now I'm delighted.

    Sure glad we didn't buy that SUV my wife thought we needed at that time! She's happy with the 6 too. Says she's never experienced such comfortable seats on long vacation road trips. And loves the mpg.

    I have a 2005 Mazda 6i sedan 4cyl automatic that i bought used from a toyota dealer. The car was a rental car, It has 14,700 miles. My problem is im getting bad gas mileage. Below 20 miles in the city and below 27 on the highway. Is there something wrong with the car? Is there something I can do to improve this? I did not notice any leaks (like fuel). I would appreciate any help I can get.

    Thank you very much.

    2005 Mazda 6i sedan 4cyl automatic ... a rental ... 14,700 miles ... Below 20 miles in the city and below 27 on the highway.

    According to Consumer Reports the Mazda6i should be getting 24/31 so your vehicle appears off by about 20%. I would bring it into a Mazda dealership for a diagnosis to see what they find. They may be able to fix the problem under warranty. Unfortunately, rentals can be subject to abuse.

    No, 24/31 is the EPA rating for the 2006 model.

    The 2005 is rated 23/28 by EPA (city/hwy):

    The CR test that I could find was in 2003 and measured 16/33/23 (city/hwy/mixed).

    When I had a 2005 as a loaner, I noticed it ran at pretty high RPM at freeway speeds, so not surprised by the low hwy mileage. The 2006 model (which has 5 speed ATX) runs at much lower rpm and gets better mileage ratings.
  • In April I bought an '06 6i hatch with the manual tranmission. With the exception of one trip to Philly (during which I was stuck in bumper to bumper traffic for over an hour with the A/C on and still got my best mileage to date, it's all been puttering around town or relatively short stretches on 2-lane state roads. To date: 28.5, 26.2, 27.9, 28.9, 27.2, 26.7, 30.8 and 26.0. don't know whether to consider that good, bad or indifferent, but at least it's pretty consistent!

    2006 Mazdaspeed 6. I have owned it for just over a month now and on 5 tanks of gas I am averaging 22 mpg in mostly city driving(between 60/40 and 70/30 city/highway). Worst is 21mpg, best is 24 mpg (highway trip)
  • waygrabowwaygrabow Posts: 209
    Just filled the tank on my new Mazdaspeed 6 for the second time. First tank was 26 1/3 mpg; second tank was almost 27 mpg. I received two speeding tickets last year, so I am driving rather cautiously now. Also, I drive very little in stop & go traffic.

  • Last three fillups of gas have shown 28.0, 28.8 and 27.9 mpg. Mainly highway driving.
  • 04 6s 5 spd auto, 32K miles. Rarely do I break 20 MPG with my mixed city/hwy driving. I thought it would have improved after the initial break-in, but never did. Additionally, this is WITH an installed K&N air filter. On trips, I've managed to get more like 25 MPG, but those aren't typical. I love this car, though!!!
  • For my 2004 6s Hatchback, MTX, 43K miles, my normal mileage for a weekly commute of 13 miles each way (2 lane hwy, 2 stop lights)+ short 3-4 mile excursions around town averages 24-25 MPG. Highway mileage for trips up to DC running 65-80 has been 28-29 MPG.

    Today I test drove a 6s with the 6 speed automatic and was amazed at how much less the engine RPMs were at 60 MPH (about 2000 RPMS vice 2500 RPMS for my MTX). That should translate into much better mileage for the auto, unless the engine is loaded too much with the lower numerical gear rating. Any 6 speed auto owners getting 30+ MPG on the hwy?

    In the 5 tankfuls it took to drive from NY to IL and back for X-mas in my '06 6i 5 sp., we got 30.1, 30.6, 30.3 31.6 and 29.7, driving pretty steady between 70-75 mph. Rainy weather out, nice weather back didn't seem to make any difference. Still have yet to make it all the way to the 32 EPA highway estimate. Now have 6500 mi. on car.

    What equipment do you have? Sunroof, etc?

    Also, how many people were in the car on the trip and how much luggage?

    I am torn between getting another 6 but cant decide whether a 6 sp auto or 5 so manual.
  • I am impressed with almost all aspects of my 2006 6s Grand Sport but the fuel economy is the most surprising.
    For my daily commute it is consistently going 29 to 30 miles for each gallon of the cheapest fuel I can find.
    My commute is about 65% highway, has more than 20 traffic lights and posted limits are 45 or 65 mph. I typically accelerate from a stop slower than most traffic and drive about 10% over the speed limit. Fairly conservative driving overall although I do speed up for corners :D

    I also feel the 6 speed auto is responsible for the great mpg numbers: it drops into 6th somewhere between 40 and 45 mph. I've never done an extended highway-only trip with this car, but I expect I'll see something in the mid 30s.

    Mine is the hatchback 6i - it came in a "sport" configuration w/ spoiler, 16 in tires on alloys, fog lights, and the other things included in that package. No sunroof or other options. This trip was 2 people with a full trunk and a few presents and such thrown on the back seat. The RPMs on the highway are between 3,250 and 3,500, which I find a bit high compared to other cars I've owned and is probably responsible for the so-so mileage. I wish there was an overdrive 6th gear or that 5th were at least a bit taller.

    At least wait until the '08 redesign, with the rumored 3.5L V6 with 6-speed manual... :)
  • I purchased a new 2004 M6S 5-door (hatch), 3.0 liter V-6 with the 5-speed manual transmission in December of 2004. I use a small spiral notebook to keep track of each fill-up (mileage, gallons, cost) along with all maintenance (oil/filter changes, air filter, tire rotations etc). I drive pretty conservatively (few jack rabbit starts), usually within 5-10 mph of posted speed limit and I don't rev the engine too high unless accelerating onto the highway or merging into traffic.

    In calendar year 2005 I put 15,048 miles on the car and used 523 gallons of fuel, which resulted in an average of 28.8 mpg.

    In calendar year 2006 I put 15,468 miles on the car and used 561 gallons of fuel, which resulted in an average of 27.6 mpg.

    The 24-month average over both years (2005 and 2006) was 28.2 mpg, not bad for the 3.0 liter V-6 engine. I'm not all that surprised at the drop in mileage from 2005 to 2006. My commuting pattern has changed (more stop-go), and we've had a much more severe winter this year here in Colorado. I also used the a/c a lot more in the summer of 2006 than I did the previous year.

    Maintenance-wise, I've been very pleased with the car with the exception of the clutch (chatter, vague engagement), which was repaired (clutch plate replaced) under warranty last year. The only other major criticism I have is with the performance of the throttle body fuel injection system and the throttle (seems to have a mind of its own at times), which I'm betting is mostly noticable to those M6 drivers with the V-6 and a manual transmission.

    Happy New Year, and happy driving - zoom, zoom! :D
