A little over a month ago I gave you a glimpse at my auto-shifting 2006 Acura TSX fuel economy. After nearly 2.5 years of ownership I remain completely satisfied each time I complete a commute.
The same can be said for my fuel consumption. The owners manual for the TSX calls for no less than 91 octane. Beginning February 7, 2006, the only octane ratings guzzled up have been 92 or 93, depending on the fueling station.
After 133 fill-ups I have averaged 25.93 MPG, or 27.53 MPG per the multi informational display (MID) located in the gauge cluster. I arrived at the 25.93 number by dividing miles on the tank by gallons needed to top off the tank; a number I feel more confident in versus the MID.
Via the window sticker, the Department of Energy was almost spot-on with the estimated annual fuel cost. $1,386 x 2.5 years = $3,465.00. According to my data, I spent $3,654.87. Pretty close.
Let’s take a look at gas price fluctuation since my first fill-up on February 7th.
Gas prices have went up and up ever since I bought the car, and the same can be said for my ownership satisfaction. To quote the February ’06 edition of Car & Driver, “It’s rare for anyone to emerge from a drive in the TSX spouting anything but superlatives.” Here’s to many more miles in the trusty “silver bullet”.
Should you find yourself wanting to crunch my data even further, here is some Excel candy.

Dude, you’ve got too much time on your hands! But you’ve inspired me to start tracking my commuting stats. 🙂
When I fill up I tack on my stats to the receipt and place it in my center console. When the console won’t shut any longer, I take them out and enter them into Excel.
@Patrick – Casey has inspired me too, and using FuelFrog (http://fuelfrog.com) in combination with Twitter makes the data collection process a matter of sending a Twitter text message whenever I fuel up.
@Michael Wender – Make sure you’re keeping your stats elsewhere. Relying on Twitter is a risky bet. 🙂
I began tracking my mileage about a month ago using http://mymilemarker.com/ and started a hypermiling experiment at the same time. Either I or my car (or both) seriously suck at hypermiling. I’m getting 30 mpg consistently in my V6 Accord.
Your dedication to do this for so long is inspiring.
@RadDevon – 30MPG in a V6 Accord is excellent mileage! You’re doing something right.
I tried using mymilemarker.com for my ’99 Accord but got lazy. That car just doesn’t inspire me like the Acura does. Ha.
Speaking of getting good gas mileage, I averaged 33 miles to the gallon on a 4-hour drive from Knoxville to Greensboro, NC simply by going the speed-limit the entire time. Amazing, since half the drive is through the mountains.
Was that in the GTI or Scion?
According to my MID, I got 31.4 MPG round-trip to Memphis and back. Not too bad.
The 33 MPG was in the GTI.
I’m using http://www.mpgtune.com/ to track my mileage, used to average 33MPG on my 97 5-speed 2.4 4 cyl altima with mostly highway driving. 30 MPG for V6 is really good, either raddevon or Honda or both doing something right 🙂 Any advice for all us out there?
[…] this site you probably know by now that I love crunching data, especially when it comes to the fuel efficiency of my cars.In late October of this year my wife and I purchased a 2009 Acura MDX to replace her aging Honda […]
Wow, great mileage man! I’m guessing you’re well over the next 80,000 by now. Enjoy your sweet ride.
Thanks Jon.
