That is low, but not too far off from my experience. I drive a 2008 Mazda 5 w/AT, and do a lot of what has been called "village" driving -- lots of stops and starts, and short trips where the engine may not get fully warmed up. With strictly that type of driving, I average 19-20 mpg. Mix in a bit of interstate driving on the weekends, and I may bump that up to the 22-25 range. Best ever was 33 -- but that was one long interstate trip w/ virtually no stops or slowdowns, and the cruise control set at 60 mph. (Which is not my usual speed.)

I had forgotten about the ethanol angle when I went to fill up last week (!).
I'll give that a try this next time...

I'm not sure why your results are'nt better. I'm also stuck using ethenol gas this time of year, but despite the very cold weather we're in I just tanked up with 15.2 gal at 390 miles for 25.6mpg.
The worst I ever saw BTW was a hair under 20mpg during a two week cold snap with all short little commutes.
I play another little game that might help. I try to see how far I can get before the temp needle starts to move. The theory is that if your burning fuel slowly it takes more miles for the motor to warm up. This time of year cold starting at around 20 degrees, I can make it over 3 miles before the needle budges.

Bought a 2010 Mazda5 yesterday w/12,400 miles, and filled the tank, refilled it today at 197 miles and got 32.7MPG, call me a happy camper after the MDX at 19.3 MPG on premium.

And how do you like the car generally by comparison with the MDX?

That's hard to say, I really liked the MDX, lots of luxury, but the 5 sure makes a lot more sense for our situation, especially with the gas prices headed north. I really like the 5 also, plenty of comfort and amenities to make me happy and the MPG makes the wallet a lot happier too. I haven't been able to drive the 5 yet due to hip replacement, it is easy to get in and out of too. I hope to get to wring it out in a couple of weeks.
#414 of 437 Not quite the high city mileage either...
Apr 01, 2011 (7:57 am)
'09 GT w/ 16k miles on it in around 30-45 degree temps all very small 10-15 miles/day trips. Tank is JUST about 1/2 way with only 170miles. 15.9 gal fuel tank capacity will make an estimated low 20's mileage... quite disapointed! I'm coming from driving a Prius getting 49 so I'm spoiled but also versed in hypermiling techniques - used here. Keeping RPM sub 2k, short shifts, coasting, even shoving it into neutral a few times (though that's too much trouble), etc. I can see if tires are an issue but the car is "new." (D versus M doesn't seem to do much difference with RPM if you don't have a lead foot - all are 2k and under).
Hwy driving got 29 and I was doing average 75 (zero stops) so I know it'll go 30+ with legal-speeds.
Looking for better numbers!

well, of course, estimating based on the fuel gauge is not very accurate. You'll have to calculate when you fill up.
I can tell you, however, that using neutral is a detriment to mileage. When you are in gear and lift off the gas, the injectors actually shut off, thereby giving you "infinity" fuel mileage. When you shift to neutral, you've disengaged the drivetrain, so now the car HAS to feed fuel to the engine to keep it idling, so you can't hit "infinity" doing it that way.

+1 on the gas gauge readings, my experience mirrors others who report 2.5 gals in the tank after "E" and the "going empty" light; so a 1/2 tank readout isn't of 15.9 gals, but perhaps 13.5 or so. That would change your math, but of course still pretty imprecise.
+1 on the "just lift" versus "shift to neutral" as well, for what's happening with the fuel system, very noticable on my ScanGauge II. Lift-off results in infinity readings (fuel shut off), neutral idling returned varied results, but never infinity.
HTH. As you note, however, Prius-like, it isn't but decent for what it is. I see 26-28 mpg on 70% highway commuting; lowest ever was 23mpg following an Audi/Corvette "parade" in the fast lane for the good part of a tankful; "Oh, we're here already, made good time!". Yes, we did! I've had a tank at 32-33 a couple of times, all interstate and 60'ish, just to see how I could stretch it. 2010 Sport 5MT.

Thanks for the "neutral" info - good to know. Only did it a few times to see what it's like - don't like it (glad it doesn't work). I was estimating before a fill-up (as it'll be a while with all the short trips/day). I'll get real world numbers once re-tanked.
In the meanwhile I was researching modifications to an ICE that could be had to squeeze more. Seems like intake/exhaust is the answer but would hate the apparent ensuing noise from the exhaust (even with resonators). Gas reaching the $4 range soon enough, payback will be faster and faster with any initial investment...
Thanks again - will report back in a week or so after a fresh tank.
