Now gone through my second tank in my 07 mz3 hatch 10.8L/100km, it will get better as I get used to the car. Anyone on here who claims to get bad mileage needs to gain some perspective. I'm going from a Jeep TJ getting 17-19L/100km. You could get suddenly worse mileage indicating a problem but other then that I don't know that it's possible to get "bad" mileage on a 3.

Just got my 07 GT Hatch. Upgraded from a 1995 cherokee so the improvement is huge, but still not quite the 28 I was promised by the interwebs...




Then again, I'm really enjoying the car and perhaps driving it a tad too aggressively.

Any suggestions for mods to improve MPG? Air filters, tires, and the like?

2004 Mazda3 Hatch 2.3L, 5 speed, 121,000 miles

I averaged around 26 mpg this winter with 50% highway, 50% city. Now that the temperature is going up and that I have been cruising around some more my last few tanks have been nearly 30 mpg.

My last tank, probably 25% city and 75% highway, I averaged dead on at 30mpg combined cycle.

Averaging 21.5 mpg combined. Roughly 50/50 plus a bunch of traffic in the city. Winter didn't help with the fuel economy either. No complaining tho... boost is SO MUCH FUN :p

I have an '06 hatch, 2.3 engine, manual transmission, with a yakima roof rack carrying 1 bike channel and a front fairing. My miles are about a 70/30 mix of highway/city driving. Over the winter I was averaging 21-23 mpg. Now that it is warming up some, I have been getting 24-26 mpg over the last 3 tanks. I typically drive around 73-78 mph on the highway, when able due to traffic.

Only 3 whole tanks so far - 29.13 mpg calculated off odometer and gallons filled. My drive to work is about 18 miles of 55-60 mph. I do a small amount of around town running. 2008 2.3L auto, sedan, stock as stock can be.


Makes me kind of sad. My previous daily driver (now winter beater) averaged 26.62 mpg over the last few years. 1997 Buick LeSabre. I'd like to think an 11 year newer car that is much smaller in size, weight, engine displacement and power could muster better than a 2.5 mpg improvement. I suppose, a lot is in the gearing.

My old company car was a 2005 Malibu with the V6. Lived on the freeway, 31.55 mpg over something like 30,000 recorded miles. That was a decent sized car that was good on gas.
