I4 4-speed auto
Depending on how crazily (or judiciously) I drive, my I4 manual mileage ranges from 21 (ouch!) to 34 (whee!) mpg. Regular, mostly-city driving during warm months is 26+, these days. Almost 30K flawless miles now
Using Chevron gasoline:
23.5 mpg mostly highway driving (heavy traffic) 20-60 mph
23.8 mpg 90% highway (light traffic) 55-60 mph
Using Shell gasoline:
26.7 mpg 90% highway, 55-65 mph
29.1 mpg all highway 60-70 mph
hmmm, never considered possibility of different gas formulations affecting mpg, any thoughts? :confuse:
I'm happy with that , coming from a V-8 Durango as my previous vehicle the 6 seems like an econobox.
Best: 26.9 mpg (rural highways 40-75 mph) @ 2000 miles.
Worst:18.3 mpg (short city trips) @ 4700 miles.
Average mpg = 21.8 (mostly town).
Summer versus winter driving has little effect (21.4 ±3.2 summer, 22.2 ±3.4 winter !) compared to city (less than 22) vs. highway (>23) .
These are with AT in Auto, since the Manual flappers are a big disappointment to me (engine brain still decides exactly when to make the shift, which throws my timing off).
Terrific handling, right-sized car
Nearly all of the 16 gallons used were on the highway.
Average mileage: 30.5, just below the 31 highway mpg advertised for this model. I'm hoping the city driving gets me at least 24 mpg, as also advertised.
3.0 Liter V6
6-speed automatic
Very first fill up, averaged 26.92 mpg with mostly highway driving. :P
It is rated at 20/27 with the 6 spd AT. If you read Consumer Reports you will read that City mileage figures from the EPA are inflated about 30 %.
I think that a lot of people round up their mileage just to impress. I use a calculator.
Sure glad we didn't buy that SUV my wife thought we needed at that time! She's happy with the 6 too. Says she's never experienced such comfortable seats on long vacation road trips. And loves the mpg.
Thank you very much.
According to Consumer Reports the Mazda6i should be getting 24/31 so your vehicle appears off by about 20%. I would bring it into a Mazda dealership for a diagnosis to see what they find. They may be able to fix the problem under warranty. Unfortunately, rentals can be subject to abuse.
The 2005 is rated 23/28 by EPA (city/hwy):

The CR test that I could find was in 2003 and measured 16/33/23 (city/hwy/mixed).
When I had a 2005 as a loaner, I noticed it ran at pretty high RPM at freeway speeds, so not surprised by the low hwy mileage. The 2006 model (which has 5 speed ATX) runs at much lower rpm and gets better mileage ratings.
The Mazda Club Chat is on tonight. The chat room opens at 8:45PM ET Hope to see YOU there! Check out the schedule
Today I test drove a 6s with the 6 speed automatic and was amazed at how much less the engine RPMs were at 60 MPH (about 2000 RPMS vice 2500 RPMS for my MTX). That should translate into much better mileage for the auto, unless the engine is loaded too much with the lower numerical gear rating. Any 6 speed auto owners getting 30+ MPG on the hwy?
Also, how many people were in the car on the trip and how much luggage?
I am torn between getting another 6 but cant decide whether a 6 sp auto or 5 so manual.
For my daily commute it is consistently going 29 to 30 miles for each gallon of the cheapest fuel I can find.
My commute is about 65% highway, has more than 20 traffic lights and posted limits are 45 or 65 mph. I typically accelerate from a stop slower than most traffic and drive about 10% over the speed limit. Fairly conservative driving overall although I do speed up for corners
I also feel the 6 speed auto is responsible for the great mpg numbers: it drops into 6th somewhere between 40 and 45 mph. I've never done an extended highway-only trip with this car, but I expect I'll see something in the mid 30s.
At least wait until the '08 redesign, with the rumored 3.5L V6 with 6-speed manual...
In calendar year 2005 I put 15,048 miles on the car and used 523 gallons of fuel, which resulted in an average of 28.8 mpg.
In calendar year 2006 I put 15,468 miles on the car and used 561 gallons of fuel, which resulted in an average of 27.6 mpg.
The 24-month average over both years (2005 and 2006) was 28.2 mpg, not bad for the 3.0 liter V-6 engine. I'm not all that surprised at the drop in mileage from 2005 to 2006. My commuting pattern has changed (more stop-go), and we've had a much more severe winter this year here in Colorado. I also used the a/c a lot more in the summer of 2006 than I did the previous year.
Maintenance-wise, I've been very pleased with the car with the exception of the clutch (chatter, vague engagement), which was repaired (clutch plate replaced) under warranty last year. The only other major criticism I have is with the performance of the throttle body fuel injection system and the throttle (seems to have a mind of its own at times), which I'm betting is mostly noticable to those M6 drivers with the V-6 and a manual transmission.
Happy New Year, and happy driving - zoom, zoom!
However, after living here for over a year, this past summer my car began giving me terrible mileage. It went from 24 to 21 to 18 and now I get 13-14 and 16MPG if I'm lucky. The drastic dropoff took less then a month. I used to go 200+ miles before the tank was at the halfway mark, now it gets there at about 110 or so. I've brought it to the dealer several times and they run all sorts of tests and find nothing wrong with it. The car feels just like it always has, nothing is hindering it's performance and nothing has changed. I bought new tires at the end of the summer and expected better results but I get the same. And yes, they're blown up to the correct amount.
Does anyone have any idea why this would be happening? I'm at 48,000 miles and my warranty is almost up. I'm so worried that as soon as it ends the dealer will then 'find' the source and charge me a ton to fix it..
P.S. Vast improvement: was at 1/2 tank with my wagon, and had about 195 miles on the trip computer. Never really notice just how many miles you drive until you really wring this thing out. I mean, 195 miles... in less than a week????? I drive too much!!!!
