I'm seeing about an extra 1mpg for every 20 degrees of temperature increase. :yesnod: Up to almost 28 now. The a/c will fix this trend though.

My only comment is that with a manual on my 1st Gen S I could pull 28 MPG, on my 2nd Gen I I can only pull about 26 MPG...Somewhat disappointed.

I've put about 400 miles on my car and am averaging I think around 18 mpg in very heavy stop and go traffic (NOVA, i95 corridor).

2009 Mazda6 4 cyl manual. Last 4 tanks averaged: 29.4, 29.6, 29.7 & 29.6. Mostly highway driving with little A/C usage.

This vehicle "coasts" better than any other I've ever driven. The last half of most city blocks I have the clutch pushed in and am moving at or near the speed limit with the rpm's at idle.

Wow, I thought the 2009 6 got better gas mileage... :(

I have a 2007 6 2.3L 30.000 miles auto that gets 23 - 24 mpg with 50/50 city/hwy. I have a chance to buy a 2009 6 2.5L auto
for about $4000 to $5000 cash plus my 07 trade-in.

Do you guys think it's worth it? I figured a brand new 6 for that kind of money plus extra gas mileage would be worth it, but
now, I'm not sure... :huh:

What say you?

Also, does anyone know any way to improve the mileage i.e. chip, exhaust etc?

Thanks for your time,

- jdocster :)

I'm getting 26 mpg suburban with the 2.5 4 cylinder and automatic trans with 9000 mi. on car. I haven't reset the mpg setting since about 1500 miles, so this is a pretty good estimation of what you can expect if you drive conservatively. Otherwise you're probably looking at 23-24.

I've been averaging 31-32mpg 60% hwy / 40% city-suburban - A/C 1/2 the time. I'm not a hard core hypermiler but I avoid hard accleration if I can, adjust my speed and coast to stops, and shift to the highest gear possible without lugging the engine. It's just me in the car. I got 34mpg 100% hwy. When I had my Dad and a trunk and back seat full of junk on the trip from PA to NC, I still got 31mpg.

Will the 2010 Mazda 6 still get the "start stop" technology? I read about it a while back on autoblog.com and I think that will boost MPG another 10% (basically another 2-2.5 mpg). That's not bad. I was waiting for the 2010 anyway just so they could work out all the bugs that a first year model has.

Um, abandoning ethanol will be a 10% boost :roll:

Anyhoo, before I had to use the A/C, I was solidly at 25.7 ---- it's low 25s now that I have to turn on the air conditioning.

I do *NOT* avoid fast starts; I tend to lay on the throttle, so the "epa estimates" are pretty conservative, since I can land in between them.

First tank of gas on 2009 2.5L, 6 sp manual. Driving was 20% / 80% - Suburban / Highway, AC on 20%. Varied driving style between very conservative to slightly "spirited" (was trying to get the feel of the car). A few times, I forgot there was a 6th gear.

28.2 MPG (US). This was manually computed with a topped-off tank.


FYI: I also have a 2007, 2.3L, 5M with 30,000 (US) miles driven the same as above. I've logged every mileage since day one. Average is 30.5 MPG +/- 1.7. Winter mileage is always the low end and it seems to love warm weather. I keep tires about 8-10% higher than rated door-jam sticker. I always accelerate smoothly and get into the highest gear possible without under-revving (lugging) the engine. As traffic behind me permits, I coast into stops either dead-stick or in the last gear it was in, depending on the desired deceleration.

Once I get used to the new 2009, I think it will do just as well as the 2007. -Not bad considering it's bigger, heavier and 20 more horsepower.

I really like this car and if it treats me as well as my 2007, I'll stick with Mazdas for the foreseeable future (Maybe 26 years like I did with Toyotas).

Quick Update...

The 2009 Mazda 6 (4cyl, 6 speed manual) has 3000 miles now. Gas mileage has been extremely consistent between 31.2 to 31.9 MPG (manually measured; miles driven / gallons used). Can't complain about that! Same driving conditions as mentioned below. The cold tire pressure is set at 33.5 PSI. The 6th gear took a little getting used to and still have to hunt n peck once in a while driving in town. After installing a K & N air filter there was a slight difference (increase) in performance when taking off from a dead stop. It will get synthetic oil when it needs an oil change -maybe that will bump the economy up a bit and that would be frosting on the cake!

Great car...

I've got a 2009 i GT w/ a little over 3000K on it now.

My 1st trip (~500 miles highway) I got about 28 MPG. When my wife drives it now, she gets a city/hwy average of low 24s. I usually get in the low 25s combined. Neither of us goes all that easy on the gas pedal but she accelerates quite a bit harder than I do and it shows in her gas mileage. My other ride is a Mercury Mountaineer that gets about 15 MPG average so I'm pretty happy with 24-25 average.

I'll add another data point. 2009, Mazda6i GT, automatic, getting 23-24 mpg with probably 65% hwy, 35% city. Kinda disappointing...

On a long trip I went on at constant 72mph I got 30 mpg, still not great.

You can check out my fuelly site in my sig to get some info about my mpg. It has steadily been getting better for about the past 9 months now. I did my first big trip which was around 70 miles both ways and was able to get around 35mpg both ways. Averaged out this tank is a bit over 27mpg right now.

I shot myself in the foot for a while though because I kept the defroster and foot vent on to circulate air in the car but did not know that the air conditioner went on when I did this. Now that I've figured that out mpg has gone up 2+ mpg since. :drive:

I don't know how accurate the calculation is on my first tank since it was dealer filled, but I went a total of 365 mostly city miles and filled the current tank to 16.7 gallons for a total MPG of just under 22. This is a little disapointing and will hopefully improve after break in. My 2009 6 I Sport with 6spd. only has 500 miles on it currently. It is a very fun car to drive, and I have enjoyed the last three weeks since I purchased it greatly.
