My family lives in Westchester County, NY. So far we have about 700 miles on the car in 2 months of driving - all local with the exception of 2 trips that account for about 100 of those miles. Tire pressure has consistently been around 34-35psi. Avg MPG has been between 12.1 and 12.7, but spiked to about 14 on both of the highway trips. We have only filled the gas tank twice so far (in NJ, which saved us $$) at a cost of about $55 each fill. I am not sure how accurate the computer calculation is, but even I was expecting to get a little better mileage out of the car. Would engine break-in have anything to do with MPG? I guess I have been a little spoiled by 4 cylinder driving - In contrast, my little 2-seater Toyota convertible gets over 30 mpg on 87 octane gas and even my '03 WRX, which requires premium fuel like the MDX, is around 24-25mpg.

Thanks for the posting. I told wife this morning not to let car get much below a quarter because it's not like prior car (Mazda MPV) that got better mileage. Ride to train this morning was at 12.1. I need to adjust tire pressure. I looked this morning and it was like 29, which is probably too low. Really disappointing. If I had known this, would have bought Mazda CX-9, which runs on regular and gets better mileage. Hopefully we'll get more postings but I too thought we'd get better, particularly in light of what are supposed to be more realistic EPA estimates on the sticker -- wasn't it like 15? I really do wonder if something wrong.

13 mpg?? Wow. I am having second thoughts on getting the MDX 2008.

I'm not sure what to make of these numbers, but I don't put too much into them - they are what they are. I never tracked MPG before and I doubt many people did either, but I think that any new vehicle that has a trip computer, especially one like the MDX's that is always accesible, just makes people more conscious of MPG. My perspective is based on only 6-8k miles of driving each year - people that drive to work everyday and/or need to fill their tanks up a few times a month will definitely feel differently.
With regards to the Mazda, I thought that it also required premium fuel (or maybe that was the 2007 model). Do you have any insight into my earlier question about engine "break-in" period possibly impacting MPG?
By the way - the recommended tire pressure is 32psi I believe, but I think that is way too low for an SUV of this size and weight, so we ride the tires a bit higher.

From what I can gather, breakin is of no real consequence. Maybe 1 mpg.
As to numbers, I agree they are what they are but I really think 12 vs. 15 is a big difference. 25% is misleading, in my vies. I also really wouldn't have bought the car if I would get that bad. We too are not big drivers -- maybe 8-10K per year as second car (clk 320 convertible) gets used in better weather.
I am interested in hearing about others.
It is interesting that we are both in NYC area, where traffic sucks, so maybe that's why we are worse than some/many others.

CX-9 is regular unleaded, with also a 15mpg city estimate. That isn't the gripe, though. It's the fact that we are consistently 25% under the so-called more accurate mpg.

An interesting thing has happened to the mileage on my '04. When my wife was driving it the computer always read 17.5 mpg for mixed driving. Now that I am driving it (  ) the computer reads 14.5 mpg. The big difference is that the '04 now only goes to work and back (1 mile round trip) The cold weather may also play a part in this. But I think the fact that it never gets to stretch it's legs has a big impact (like you city dwellers) on the mpg.

Thanks. Even your 14.5 is better than our 12.1, with about 1,000 miles on odometer to date. Clearly, the city driving is bad and I know my wife has heavy foot but hey, at this point, I'd be happy with 14.5. Also, need to add air to tires to bring to spec or above.

To be fair, these numbers are the extremes. Our '07 has been getting 17+ mpg in mixed driving (probably better now that the wife is driving it) and we average 22-23 mpg on highway trips.

Extreme in what sense? This is what we get every day driving kids to school, after school sports, train station -- all local driving. The fact that more than one of us has it suggests it is reality for "city" driving, even if you are in the suburbs.
