We use it mostly for running errands (commute by subway). I'd say the traffic is generally comprable to any city. Lots of traffic lights, bumpy roads, etc. It's not like we're always in a traffic jam, though.
Sounds like it's worth bringing up with the dealer, though.
Thanks for the input, folks.

Yeah, those numbers are REALLY low, so that would warrant a visit to the dealer for me. Though, like I said, I, normally, average about 19 to 21 city in NYC, at least those numbers aren't too far away from the 21mpg EPA figure. However, on highway trips, I routinely get higher than the EPA figure. My best highway fuel economy was about 34mpg, which is a lot higher than the 28 EPA figure. Your numbers are a lot lower than those, so yeah, take it to the dealer. I hope it goes well for you!

I took mine to the dealer today. I'm still averaging 16-18 mpg intown. After about an hour, the upshot was "Since you're not showing any warning lights, and the computer doesn't show anything wrong, we have no idea." Seemed like a classic example of the modern overdependence on computers -- no professional curiosity at all. They told me that when the Autozone guy turned off the "check engine" light, it also wiped out any history of whatever caused it to illuminate. (It was almost certainly caused by a loose gas cap). They also tried (as I and some here anticipated) the old "Well, you don't have that many miles on it yet." I then asked how many miles I would need to drive it before I should expect to start getting the same MPG as everyone else, and exactly what change(s) would be taking place during that interval that would result in that MPG improvement. All I got was s blank look and "I dunno." The ever-so-nice lady at Mazda didn't really have a lot more to offer, other than buying gas at a different station, and the usual gas-pedal suggestions. Opened a file for me, too.
I guess I'll run another tank or two through it, so I can truthfully say I complied with their suggestions, and then take it back in if the MPG doesn't improve. All suggestions are still welcome!

My MPG started getting stable after 2-3K miles
My only non-expert suggestion is to ask them to update the ECU with the latest code they have, other than that I would try a different gas station just to make sure the gas is not the issue

Interesting, I live in Orange County California and I have owned the Mazda5 since March 08. I have had the same problem with low mileage within the city. I have been getting better MPG as the car has been breaking in but, only Hwy miles. This last Gas Tank and with an oil change, K&N Filter, Hwy Miles were about 31.5 miles--107 miles to 3.4 gallons-. In the city, today I got 86 miles to 4.6 gallons, not worth doing the math on this one. I use a Yaris for City Driving and the Mazda5 for Hwy.

Had the vehicle for about 6 weeks. Starting out with a full tank of gas, doing an average of about 60% highway with cruising speeds upto 75mph we have 1638 miles using 63.5 gallons of fuel for an overall average of about 25.8mpg.
Highest tank average 28.5mpg 80% highway.
Lowest 22.0mpg with 100% city driving / no traffic jams.

round trip from fl to southern new jersey last week 28 mpg highway.my question to all that are getting 31 or better mpg are YOU TOPPING OFF TANK? I ALWAYS TOP OFF TANK [am i doing wrong by this] if i had shut off pump at click mpg would have been better. from florida to new jersey by way or I-95 CHEAPEST GAS WAS IN SOUTH CAROLINA, LOOKS LIKE GEORGIA IS NO LONGER THE PLACE TO FILL UP GOING NORTH. ACTUALLY GAS WAS ALSO CHEAP IN VIRGINIA [who would figure that] driving a 2008 GRAND TOURING

We also have a M5, 08, Touring, the wife gets 30 to 33 MPG with most 31 & 32, 5000 mi. on the car. She drives 58 in 55 zones and 68 in 65 zones. 80- 90% hwy being more like urban driving, example it's 40 mi. to our lake house with 3 small towns and one small city to go through, I guess what I'm saying is that her highway miles are not without interuption. The city miles are more like suburban (city of 56000) with none like NYC or Chicago. She fills to the top as well as she can, at the same station and same pump as much as possible and runs around 400 miles between fills. We love the M5.

gas light comes on really early?

We've had our M5 for three weeks now- it has a total of 335 miles on it and the gas light was on for two days (only drove about 15 miles in those days- maybe less). My husband filled the tank and it only took 13 gallons. Is it typical for the gas light on the M5 to come on that early?
That does mean we ended up getting about 25 MPGs on our first tank of gas. Mainly city driving. Not too bad. How many miles until it's considered "broken in"? Can we expect to continue having 25 MPG's on average? Will it increase?
Otherwise I've been very happy with our M5 Sport automatic.

Yes, that's one of the first things I noticed on my 5's. I had a 2006 5 Touring at first, and I noticed that the gas light does come on a lot earlier than in other cars. The same is true for our 08 Grand Touring, the light comes on a little prematurely, in my opinion. I can squeeze a LOT of miles while the yellow gas light is still on. Don't know if I should. But, with gas being so expensive, the longer I can hold out on filling up the car, the better.
I normally fill up with about 14 gallons - clicking the gas nozzle a few times, of course. The capacity of the tank is 15.7, so it has a good amount of reserve on it.
