2100 miles so far - worst tank (first tank) 19.829 mpg
best tank (most recent) 22.495 mpg
 
So far, each tank has improved - just had first service performed yesterday, so hopefully will continue to see improvement. My driving is combined and very spirited - this car does not seem to want to travel at less than 80 mph.

A while back a couple of punks in a slammed and fart-canned 240 SX floored it when I pulled out to pass them. My wife wasn't with me so I nailed the throttle. In an instant I pulled on the morons by something like 8-10 cars. When I checked the speedo I was north of 100 mph. Whoops...

Wrong forums for this, but I am thinking about getting a 09 Mazda 3i Touring. If the dealers are bad, I will have to second guess my myself.
 
I don't want to deal with bad service or "denied" warranty work for changing my own oil.

I laughed and laughed at that phrase! And then I continued laughing when I thought about the look which must have been on those punks' faces.
 
Priceless!
 
To stay on topic, I filled up the other day (mostly highway driving) and had averaged 24.42 mpg with that tank - very happy with that!

In the United States, no dealer can deny warranty coverage on engine related issues when you do your own oil changes; if (and that's an important "if") you keep all of your reciepts and oil change logs.
 
Best regards,

Not bad; I just got back from an overnight trip which consisted of interstates and rural two-lanes. I averaged 25.32 with my MS3. But I was showing uncharacteristic restraint...

The first 7,624 miles... by shipo

After 3 months and 4 days I've racked up 7,624 miles. During that time the car has been driven roughly 80% on the interstate where I usually drive at speeds somewhere between 70 and 80. In addition to the obvious "break-in" mode, it's been cold up here with maybe as much as 30% of my driving done in temperatures within ten degrees (either way) of zero Fahrenheit, which as most folks know is not exactly good for enhancing fuel economy. And now, the numbers:
 
Car: 2009 Mazda3 i Touring Value Edition 5-Speed (2.0 liter engine)
Gasoline: 259.556 Gallons
Mileage: 7,624
Average MPG: 29.37
Best Tank: 406.1 miles / 32.78 mpg
Worst Tank: 339.3 miles / 27.38 mpg
 
All in all not too bad given the conditions.
 
Best regards,
Shipo

Results for all of my car's fillups are posted at www.brianbauer.org. See the ones for Chesterfield, VA.
 
My car's average based on all fillups for the first 60k miles is 38.6 mpg. Results per tank have ranged from a low of just over 32 mpg for the first fill up during initial break-in to over than 45 mpg averaged over one 624 mile tank. For some partial tanks I've calculated as high as 53 mpg. Take that Prius owners!
 
The 3i can produce awesome mileage if you're willing to drive it smoothly and with some restraint. I purchased a ScanGauge II a few years ago and have learned a lot from observing the data it can provide. At a steady 50 mph on fairly level ground in light winds I've seen 53 mpg in my 3i. When you dig into the throttle though the mpg can drop significantly.
 
After 4 years I'm very satisified w/the performance and reliability of my 3i. So far I've experience no problems at all and the car's fuel economy has more than exceeded my expectations.

Smoothsailin:
 
Those results are outstanding! Are you practicing hyper mileage techniques? (coast in neutral, california stops, etc..). My son has an 08 with the same engine and is getting 28-29 around town. Of course, he is 19. I'm looking at the 10 with the same engine.
 
Thank you.
