I was out of town when Donna sent out her e-mail looking for 2009 Mazda 6 logbook data to populate her October fuel economy update. Here are some Mazda 6 fuel economy facts:
Miles driven: 20025 (in 11 months)
Best tank: 30.2 mpg (EPA highway = 30 mpg)
Worst tank: 18.7 mpg (EPA city = 21 mpg)
Average mpg for all miles: 23.7 mpg (EPA combined = 24 mpg)
Number of fill-ups: 68
Number of fill-ups of 15 gallons or more: 15
Number of tanks with 350 or more miles: 14
Number of tanks with 400 or more miles: 6
Greatest range on one tank: 453.9 miles
Three things:
The Mazda 6 hasn't gone on many long-distance road trips, but it has met or exceeded the highway rating a couple of times.
The lack of road trips may not lead us to 24,000 miles in 12 months, but it will be close. We're not doing bad for a car that's mainly seeing commuting duty.
Its overall mpg over 25,000+ miles is just about equal to the EPA combined rating. It is equal, in fact, if you round it up to the nearest whole number (23.7 --> 24) as the EPA does for its window sticker numbers.
Dan Edmunds, Director of Vehicle Testing @ 20,055 miles

Your worst tank on the 6 is nothing compared to other cars you guys have had.

Edmunds came close to the EPA estimates? How the hell did that happen?
I'm discounting worst tank, as that was probably a thrashing day.

Why no road trips? I thought this car would be a comfortable cruiser. I guess when the Flex and 750 are available, why would you ever choose a regular car for a road trip right?

I like seeing your numbers next to the EPA numbers. Very helpful to see how the real-world numbers match.
