Fuel formulations can vary in certain states; I don't think PA is one of those however.
 
I'd check your tire pressure and maybe bump it up to 36psi all the way around if you don't mind a slightly rougher ride. My only other guess is that you drive a bit faster than others.

I've only had the car 3 months; could it have low tire pressure already? I suppose my driving style might be a factor, but to such a great extent? Some people are claiming an average of, for instance, 27 MPG, fully a third higher than my mileage. Very mysterious. I think you're all making it up just to depress me.

Toyota Yaris: 2300 lbs
Matrix/Vibe: 2700 lbs
Mazda5: 3300 lbs
Rondo: 3500 lbs
Dodge Caravan: 5600 lbs
 
how many miles are you getting on a tank? maybe still breaking in but I'd ask the dealer if it doesn't step it up. I'm usually filling up about 13 gallons when the fuel alert light comes on. I don't think I've ever been below 280 miles on the tripometer in that situation - at 19mpg you would only be like 250. Usually now in the 330 +/- 10mpg range on this bad MN gas - mixed driving and a/c on frequently doesn't seem to impact much.

The gas station locations vary, still I got a decent 24.5MPG, mostly city driving last time I checked
 
Given that is hilly around here I was expecting a worse number. I can't complain...

Re. fuel mileage . . . I get 26MPG with our Dodge Grand Caravan with the 3.3L V6 with the A/C on during trips. I've been seriously looking at the Mazda5 since we are now "empty nesters" and don't need all of the room of a large van. But, with over 160K on the Caravan, and on the same 4-speed ECT automatic transmission, I've actually been quite pleased with the vehicle. I would certainly expect the Mazda5 to do over 30MPG on the highway.

PA. Why?

 
Hi daharon. We also live in PA and have owned the MZ5 for almost 2 years. We have filled-up tanks from places ranging from WaWa to Cumberland Farms (87 oct gas). I should say that those are not the best gas stations around but still we get ~24.5MPG city and ~30-31MPG pure highway. My only suggestion would be to take it to the dealer in the next service appointment or and ask them to check how the computer is handling the gas-air mixing into the engine (or something like that) as 19MPG seems really low

I have to say that I have ALWAYS thought that my city mileage was WAY lower than what everyone here reported for the MZ5! I LOVE my 5, but DO feel that the city mileage can improve. Recently I had to fill up with only 250 miles on the odometer - and I filled up with about 13.5 gallons, so that gives me LESS than 19mpg (18.52mpg all city driving). I have always felt the same as you - like if everyone here is exaggerating their claims, but that just cannot be. Perhaps it's our driving style? I don't know, but I'm not that much of an aggressive driver - I like to drive as smoothly as possible. Nevertheless, I do live in NYC where there is constant traffic and I take majorily very short trips (like taking the kids to school, then coming back to the house to park it in the drive and then leave for work on the subway), so perhaps that also affects fuel economy.
 
As far as highway mileage goes, however, I have been VERY pleased with my 5 as it has consistenly achieved a significantly higher fuel economy rating than the EPA suggested. The best fuel economy I got on the highway was 450 miles to the tank with a fill up of 13.5 gallons, which gave me 34.61 mpg! So, that's cool. But the city mileage leaves much to be desired for this four cylinder vehicle. Do you guys think I should have the dealer check it out? I've had my 5 since July '05!

I think the DOT needs to air certain ads a little more often.
 
Sarcasm aside, the pressure can be low from the start. I have received new vehicles with both too much and too little air. If checking it weekly is not realistic (it's not for me), try to check your tire pressure at least once a month.

You are getting decent numbers in highway, but for the city values please note that you are talking about NYC, not a little "town" in PA. When I stated city MPG it is more of "town" driving , meaning stop-n-go traffic, yet more fluid than NYC I'm sure. In other words, we may not be comparing apples to apples.
 
In another forum (not Edmunds) there was a mention that the MZ5 computer program was off-tune so it was wasting more gas than needed when injecting it to the engine. Reloading the computer module with tuned numbers for the gas mix was a way to fix it. Again, I'm not the one who did it, it is just my opinion (the car is still under warranty, so I do believe there is nothing to lose and I would give a try during the next service appointment)

Oh yes, I agree with nissmazlover. I don't see a need to exaggerate. I love the 5's style, flexibility and design but, believe me, Mazda is not paying me a cent for driving it so, if the MPG had been very poor compared to the expected standards, the MZ5 would have been "For Sale" in the first opportunity, no doubt (yup, we also bought ours back in Jul/Aug 05) , plus I would be so upset I would be ranting in this forum instead of praising

Yesterday I discovered that I do get much better mileage on the fast-running highway, 30 MPG, so maybe its just that my city conditions are worse than for others (I'm in Philly). coolmazda5, can you tell me where you saw the discussion about the computer injecting too much gas? I'd like to have something solid to talk to the service guy about when I take the car in to the dealer for its first checkup.
Although, if I get 30MPG on the highway, would that indicate that the engine is performing fine, and the problem must be my driving or the city conditions?
