Mazda5 real-world Mileage numbers

i recently got my highest mileage number - 30.7 on a 5-1/2 hour drive to New Hampshire. '07 Touring model, AT, driving about 75 mph, approx 9,000 miles.
 
Bought my 2007 AT a few weeks ago, used with 9500 miles on the odometer and I've only filled it up twice. Got 25.1 and 30.0 mpg.
 
New 2007 numbers, 5 AT

Hello Everyone,

Just purchased a new 2007 Mazda 5 Touring AT at the end of September.

First tank of gas - 26.38 MPG
Second tank of gas - 26.35 MPG

I usually have a heavy foot, but I've been very gentle on the gas during the break-in period. Not a lot of highway driving, but there are lots of long 40 - 55 MPH roads around Antioch, IL.
 
I must confess that our 27+ mpg average has more to do with driving style than average efficiency. If we drove it like every other nut on the road, 23-25 mpg would be more typical. But instead, we do things like short shifting and keeping the revs low to coasting longer distances to known stops.

yeah we tend to drive conservative most of the time, occasionally I put into sport shift mode and rail it just for fun. Gotta hyundai rental car now and I gotta thank Hyundai for making me appreciate our Mazda 5.... the 5 gets almost the same mileage as this elantra... pretty sad.

On a side note we may be moving to Eugene... any suggestions on places to Live? I hear 4j schools and Westside?
 
3rd tank of gas

Just filled up my 3rd tank of gas last night.

First 150 miles, I avoided the highway and drove with a much heavier foot than during break-in, though I wouldn't say I was driving it hard.
Second 200 miles, all highway, mostly 68 - 70 MPH.

29.23 MPG.
 
This is kind of unscientific, but I recently topped off the tank after 169.5 miles of driving. I added 5.45 US gallons of fuel. So my calculation is 31 MPG. This was mostly flat highway driving at 55 MPH.
 
2 tanks in a row, with great results.
I got 36 mpg in Denver freeway commuting. I rarely go above 65, part of the commute is a 55mph speed limit.
I have to concentrate on throttle control, here's what I do:
1. only move the throttle plate if I need to. constant throttle position is key
2. speed limit
3. I shift from 1st to 3rd to 5th, or from 1st to 2nd to 4th to 5th. This is always done under light load, constant elevation, not lugging the engine or otherwise loading the drivetrain. If I need to move I shift normally. The onramps I have to use are very long so I don't need to max accelerate. I'm also not driving like a grandpa being a roadblock while accelerating; I usually accelerate faster than the SUVs that everyone in Denver drives.

I commute 50 miles/day, about 38 of those miles are mostly constant speed freeway around C470 on the southwest side of metro. I couldn't believe the mileage numbers, but I've repeated it for 2 tanks. 9 gallons and 325 miles for the last tank. This is with 85 octane fuel.

Do you post your results on TrueDelta or GasSavers.org? I have a 2.5 mile commute, so our mileage numbers are just a tad different.

Interesting shifting technique. What PSI are you running? I have 42 PSI in my tires, and just roll like crazy down hills.

I don't think I've seen your 5 in the area. I'm down in the Broadway/C-470/Lucent/HR Pkwy area.

30.33 Mpg

I finally did it! I had about 120 miles of highway driving out of my 358.5 miles.
 
Proof that it isn't a fluke. Another tank of 36.5 mpg driving!
Tire pressure is 36lbs, I'll have to verify.
It takes a fair bit of concentration to drive for best economy, you have to watch traffic flow, stoplight behavior...you know, all of the stuff you should be watching anyway.
 
I have noticed great mileage in general when driving in the high altitude in Colorado. Something about the altitude and fuel blend...

50 mph gets very good #'s also... you running mostly under 60mph?
 
65mph on C470 for about 14 miles, 55 on Morrison Rd for about 3, surface street speed, including a school zone, for 5 miles.
 
Fuel Economy Conversion made easy

Given how diverse we are in this forum (Scottish, English, Dutch, Swedish, Canadians, Canadiens... US, Hong Kong, Imperial Gallons, Socialist Liters vs. Canadian Litres, left vs. right hand drive, light vs. heavy stones, Kilometers vs. Kilometres... (, oh shoot, it does not go that far)) I found a good place where to do fuel economy conversions:

Wow!

Took the 5 on a ski trip yesterday. Filled up in Denver, drove to Winter Park which is about 70 miles each way and includes a drive over Berthoud Pass- elev 11,300'. Was -5 F and very windy on top, about 10 degrees and quite breezy on either side. We hammered hard (running 65-90) on I-70 each way to/from Denver metro area. Had 3 passengers and ski cargo aboard. Filled up again this morning... achieved 37.8 mpg!

I keep a very accurate log of all fill-ups. I am thrilled and astounded on how well it drove and performed. Yes, this is with the 4AT used in mostly manual mode- averaging 3-5k rpm's during most of the mountain run.

Woo-hoo! (drive2)
 
lol. I got 29.7 once on a highway trip to kentucky. My wife averages anywhere from 20-24 on a tank in all city suburban traffic. I got 22 on all highway on my 1st tank of my 5, then again, I drive through lousy stop and go, then go 80 mph, then 10 mph....man I hate toledo traffic. Im slowly driving more like a grandma as I have this 5 as my primary car now...but Im still a left lane kind of a guy, im also the same guy that wants to merge on onramps at a faster speed than everyone else.(nailbyt)
 
recent trip to Disneyland from Northern California. at 70mph we were getting right at 30 mpg. At 75 mph we were getting 28 mpg. with a 4AT, loaded with 3 adults, 2 kids and our luggage.
 
achieved 37.8 mpg!

You must have hooked up to the ski lift on the way up the mountain and then coasted down on the way home.

I find 37.8 hard to believe under those conditions.

The best I have ever achieved is 30.4 on a summer day cruising at 70-75mph on an open freeway.
