Use Fuelly to track your fuel economy

How fuel efficient is your vehicle? Do you ever get the suspicion, as I do, that your car’s gas mileage is getting worse? Have you ever wondered how your mileage compares to other drivers? And what about the estimated mileage touted by the car companies? Does a Mini Cooper really get 37 miles per gallon?

Matt Haughey and Paul Bausch have launched a new site called Fuelly, which allows users to track their vehicles’ fuel economy and to compare data with other drivers. As you enter data for each fuel up, Fuelly tracks your average number of miles per tank, your average cost per tank, your fuel efficiency, and more.

If you’d like to compare information with other users, you may:

Fuelly is brand new, so data is scarce. Over the next few weeks, however, users will fill their tanks, and then people will then be able to compare mileage and track their own vehicles’ performance. (For a preview of extended data, check out dredpyrate’s 2004 Mini Cooper, which has data all the way back to the first of the year! It gets 32.8 miles per gallon.)

I think this is a great idea. Fuelly taps the power of the masses to compile real fuel efficiency data so that users can find ways to save money. Brilliant. Because Fuelly is new, it is not without bugs. Haughey and Bausch promise to squelch these soon, and to add new features, such as metric units and support for additional vehicles (like scooters and uncommon cars).

    Awesome! My husband and I have gotten into hypermiling recently, and I think we’ll love this.

  2. Solomon says 08 August 2008 at 11:34

    Mine is very efficient. I get about 60-70mpg out of it. That’s not using any special techniques, either. It’s the fruits of a 602cc engine. 😀

  3. Shruti says 08 August 2008 at 11:43

    For personal tracking (without the comparing) there’s

  4. Stacy says 08 August 2008 at 11:47

    A similar, government-created site has been around for years:

  5. Steven Fisher says 08 August 2008 at 11:58

    Looks useful, but without metric support it’s just too much bother. We’ll see if they come out with that before someone else puts up a better site… 🙂

  6. LAM says 08 August 2008 at 11:59

    A similar website is My Mile Marker:

  7. Brack says 08 August 2008 at 12:18

    I use FuelFrog… it integrates with Twitter, which I like, but doesn’t have the social information that Fuelly looks to provide…

  8. Another Personal Finance Blog says 08 August 2008 at 12:27

    I get about 22mpg in my 1998 Subaru Forester. Every time I fill up, I write down the date, total mileage, mileage since last fill-up and gallons of gas used. Then I calculate my mileage to see how I did on that tank. It would be great to compare to owners of the same car.

  10. average reader says 08 August 2008 at 12:56

    You all should get rid of your car! I don’t OWN one, it’s implied that I’m smarter than you, therefore, do the same.
    Or, couldn’t you just rent one when you need it. It’s more frugal!

  11. Amy F says 08 August 2008 at 13:08

    I have obsessively tracked the mileage of my ’99 Civic since I got it 9 years ago. I think I’ve accidentally missed writing down the mileage/mpg about half a dozen times in its 112,000 miles. I just opened a Fuelly account — I’ll see how far back I can go before getting tired of inputting data.

  12. Mat says 08 August 2008 at 13:16

    lots of data already present, metric/imperial/us conversion, comparison, easy search engine

  13. Luke @ Money & Fitness says 08 August 2008 at 14:01

    How much does what the manufacturer say vary from what people are actually getting with their car?

  14. Mike says 08 August 2008 at 14:54

    It allows me to put in the engine info, but I cant see that info for the other trucks.

    I’m not sure of the estimated mpg it gives.
    My Ranger initially was 29mpg highway when I bought it. But if you look at with the revision on how they figure mpg, my Ranger is now 27mpg. When I picked the engine type in Fuelly it shows the old EPA MPG estimates of 29mpg.

  15. Cheap Like Me says 08 August 2008 at 15:39

    What a great idea! I have been wondering about how to find true-to-life mileage for specific vehicles since we averaged 51 mpg in a Kia Spectra that we rented on vacation.

    I am participating in a local pollution-reduction effort, Driving Change, in Denver, Colo. I input fuel usage, and the site tracks my speed, hard braking, fast starts, etc., along with car model, to determine how much I’m polluting and whether I waste gas. Voluntary Big Brotherism.

    @Another Personal Finance Blog, we average very close to what you do in our 2004 Forester (ranging from about 19 to 25, usually 22ish).

    @average reader, some of us would have to rent daily, which isn’t frugal at all! 🙂 But you are fortunate & admirable to get by without a car.

  16. Jerry says 08 August 2008 at 16:11

    We are about to move to Europe and will be going without a car for the next few years, but I like this site and the others like it… it will be nice not to have to worry about mileage for the immediate future (or insurance, etc.), but I will probably use the site for comparisons when we come back and are looking for a high-MPG vehicle (hopefully they are selling even more of them then!)…

  17. Another Dave says 08 August 2008 at 17:52

    Amy @ 1:08, a woman after my own heart. But, I don’t see you on there yet, unless you got tired of putting in data at 4 fill ups. See my 2000 Subaru Outback with 185K on there averaging 27mpg. My next vehicle will be a Civic. I hope I get better mileage than some on the site, and suspect I will.

  18. leigh says 08 August 2008 at 18:45 has a mileage database and lots of info about hypermiling for hybrid and traditional car drivers.

  19. Norm says 08 August 2008 at 21:09

    About like comparing apples to oranges, without knowing the rest of the story engine,transmission,two wheel or four wheel drive etc.

  20. MoneyBlogga says 09 August 2008 at 08:15

    Someone I know just got rid of their Mini Cooper because they didn’t get the mileage they believed they would. I have a 10 year old Geo Metro which has been reliably used for commuting daily – average 45mpg. It’s about to go into the paint shop for a sprucing up.

  21. Richard @ Student Scrooge says 09 August 2008 at 23:20

    Very interesting — I’ll have to keep an eye on this. I’ve tracked my own mileage for a while now in Microsoft Excel — I think it is a good idea as it not only allows me to monitor the financial health of my car, but also to keep an eye out for any changes in MPG that might signal a problem with the car. I like the idea of aggregating the data in a social sense, so I’ll have to give this a go. Nice!

  22. sunny says 10 August 2008 at 17:21

    I just bought a 2007 Subaru Forester (my kid needed a new car so she got my 2002 Jeep) so far averaging about 26 mpg, unless I drive on the freeway then it drops (really) to 24 mpg. Wish giving up the car was an option but I live in the boonies and my employer won’t consider telecommuting.

  23. Glen says 11 August 2008 at 07:46

    I run a similar service at It’s still in a fledgling state, and doesn’t have nearly the userbase as Fuelly, but I’m hoping to work on that.

    Any suggestions would be greatly appreciated!

  24. Russell Heimlich says 11 August 2008 at 12:49

    I’ve been using Fuelfrog and love being able to update it from my phone. Here’s my review ->

    Pretty basic though lacks the comparison features of Fuelly.

  25. Patric Watson says 06 January 2009 at 08:28

    A new website just launched:

    In addition to tracking fuel spending and fuel economy, it lets you select the group of cars to compare your MPG with. You can select by Model Year and Location. It is much meaningful than comparing a car in Alska vs a car in Florida (weather factor).

  26. Molly says 13 February 2009 at 04:54

    I’ve been using for almost a year – it’s so easy to use that even my father started doing it, after I told him how I was saving money. There’s a good blog there too.
