Hey guys, one more thing about this new Mazda3. I have 1500 yet I cannot get more than 290 miles on a full tank (I'll actually be just short by the time i refuel here).

I read that I should expect 320-350 (500????) miles per tank with the 2.3liter. Is there something wrong, or something I can do, add something to teh fuel, whatever, to get better mileage? The big 3 mod help here? I only have a 350 watt amp in the trunk, nothing near the system most you guys have (BTW, every deep bass hit dropped the voltage from roughly 14+ to 13.0 volts at the bat, but thats much louder than i normally play the stereo). I have been driving like a grandma.

Thanks.

I have a mtx and the first 3 month of having the car I would get 280 at the gallon now I get like 320 is just the break in period that was taking fuel after my first oil change it went up. I have only 4,300 miles in my h/b

remember that we have a 14.5 gallon fuel tank. So even if your light is on you usually have another couple of gallons. My MPG was worse during break in. I changed all fluids to full synthetic, a K&N filter, and use premium fuel and I am getting an average of 24-25 MPG in the city. That is with mediocre driving. Sometimes getting on it and somtimes driving mellow.

Got an 07 HB touring with ATX back in the middle of February. So far I have about 1500 miles on it and I am getting about 30 - 33 mpg highway and about 22-23mpg in the city with heavy stop and go traffic and a lot of hills. Doesn't sound too out of the ordinary to me.

wow, i thought the 5-speed auto of the 06-07's would make a big difference compared to my 4-speed 05 in gas mileage, but it seems thats untrue. and, i drive my 3 the way it should be driven, fun and fast. glad i didn't upgrade to an 07, ill bet mine is faster stock too. i don't know all the technical crap on gearing, but i would assume 4 gears would get you there faster than 5, but cruising with 5 should get you better mileage. is this correct?

thanks,
tim

I have had my three for about 2 months now and it has 4k miles on the odo. I started out only being able to get about 270 miles per tank, but at about 1500 miles i was putting about 310-320 miles per tank and putting in around 11 gallons of fuel, i drive about an even 50/50 split between city and highway and average driving not too slow but not too fast either. I have a '07 MTX hatch. I guess it would just depend on the type of driving you do as far as gas mileage.



Edited for spelling :?

I have an 07 2.3 S-GT ATX and was getting right about what you were getting when I first had it. Now I'm usually at 300 miles or a little over when I get gas but my light isn't on. I usually put in about 11 gallons or so. On my recent trip to SoCal from the bay area I got 31 mpg and went 344 miles on 11.098 gallons. I now have 7K miles on my car and see a little bit better mileage but I'm still averaging 24-25 mpg with mixed city and highway driving.

I turned on the trip computer using the guide here in the forums and i have noticed that mazda has apparently programmed in a failsafe for idiot, because i was driving and the trip computer said i had 30ish some odd miles left on the tank when the fuel light came on, so i went to the gas station and filled up a whole 11.9 gallons, its a 14.5 gallon tank and at the gas mileage that I am getting i should have had something like 75-80 miles left not 35 and it seemed odd the fuel light came on so early, in my old beetle when it came on you needed to get to a gas station fast cause there was at most 1 gallon left in the tank.
