Tim H. said:5-speed, mixed driving and I got about 23 MPG on the 2nd or 3rd tank of gas. A bit disappointing actually. Maybe it will get better after the engine breaks in?

I'm not impressed to say the least. See my posting on the Hesitation. Anyone think these are connected? Add in the recall "fix" and my gas mileage takes a dive. Makes me think I'm driving around with an anchor hanging off my bumper. I'd like to know how you folks are getting 25+mpg consistently.
Antonio DiMarco said:I have a 5 and don't have any hesitation. In fact it feels more responsive after the recall. It definitely doesn't feel like there is an anchor hanging off the bumper .
The recall fix did not change the 5 speed's PCM. When does it hesitate?
FYI, I'm getting similar mileage numbers in the low 20's (though I have not seen 15mpg). My 3S gets 22 to 28mpg. Remember the 5 is larger and not as aerodynamic as the 3.
Climate has a lot to do with fuel economy as well. MA has been pretty mild lately (40 to 60). How is it up in BC?
Rich A. said:O.k., I'm coming back down to earth on my gas mileage figures.
Here are my two tanks so far:
1) 333mi, 11.9gal = 28mpg
2) 330mi, 14.28gal = 23.1 mpg ?? what the !??
There's two things going on that I think are going on (boom07)
1) I'm beginning to think that my first fill-up didn't quite fill it up. If that's the case, then perhaps the car should have taken another 1.5gal or so which would have given me 24.8mpg. I recall on this last tank that I was surprised to see how quickly the gauge dropped to 3/4 tank after only 70mi. I just filled up with the 14.28gal and the gauge is farther above F than it was on the 11.9gal fill-up... evidence that it wasn't quite full, even though I thought I topped it off. So if the last tank was say 1.5gal low when I started driving on it, my latest calc would be 26mpg. Having seen the above post about a bladder tank, perhaps this is related.
2) I did more city driving with more people in the car over the holidays which would naturally decrease the gas mileage anyway.
So maybe I'm really getting about 25mpg on my "semi-rural/city" driving and not 28? Hmmmm. We'll see how the next few tanks go. 25mpg seems more realistic though.

Have you been running the defrost the whole time?mazdaFIVEmike said:Update:

Does anyone else think these numbers suck? Needless to say - I'm going in for a service check this week - Its definitely first on my complaint list. (rant)

When you run the defrost it cycles the A/C compressor which will make your economy drop. Also, the fuel map has more than likely changed for the cold weather. It's probably running richer until the engine reaches operating temps (much like the choke on a carb'd engine). Also, are you letting the car run for a few minutes before you get in so it will be warmer for you? If so, that's where some of your gas is going too.
I had my mileage #s drop this winter too...I was getting into the mid to high teens (MPG). But by off the defrost and not letting it idle for ten minutes before driving I've managed to get back into the low 20s.
