    I've been doing this for the last 3 years.

    This is all calculated by miles and gallons per fillup to 1st click. I try to use the same gas station as often as possible.

    2008 VW GTI 4 door DSG (Tune/Intake/Exhaust) Rated 22/29/25

    Highway: 70-80MPH
    City: fairly quick starts, 5-10 MPH over
    Track: pushed to the limits of car/skill

    2010 average: 24.429 MPG
    2011 average: 22.332 MPG
    2012 average: 23.075 MPG

    2010 best tank average: 29.511
    2011 best tank average: 27.083
    2012 best tank average: 29.167

    2010 worst tank average: 10.835 (Road America)
    2011 worst tank average: 7.892 (Autobahn Country Club)
    2012 worst tank average: 7.692 (Blackhawk Farms Raceway)

    I just look at the car's MPG calculator and knock off 10% :p

    How do your manual calculations compare against the car's computer?

    I might if I drove a lot. My 2010 has 9K miles on it and stays in a garage. It'll last 20 years easy at this point (and I spend very little on gas).

    I don't formally keep track of it but I calculate it every time I fill up.

    We record everything in the wifes car.
    date\gallons\price per gallon\miles per tank\total mileage

    In my personal car and my bikes, I check MPG every tank full using "trip miles\gallons accepted" and as long as its consistent I don't write it down.

    i keep track of miles, gas prices, gallons from when i bought my car and all the service records.

    tracking miles, gas, and gallons was just a hobby to look at trends. I dont find the information very useful just interesting to look at.

    2008 - AVG paid Gas/gallon - 2.43
    2009 - AVG paid Gas/gallon - 2.62
    2010 - AVG paid Gas/gallon - 3.03
    2011 - AVG paid Gas/gallon - 3.70
    2012 - AVG paid Gas/gallon - 3.90

    Yes I do, pretty anal about it :)

    My car is older than trip computers but I have a ScanGauge that is better than most built-in systems. It's fairly accurate, usually within 0.2 MPG per tank (<1% error). I use an app on my phone to permanently record the stats. The PITA is when my wife drives my car and does me a "favor" by filling up the car but not synchronizing things so I have to start a new history.

    Since late last July (~7500 miles ago) I'm averaging 29.73 MPG with a best tank of 31.8 and a worst tank of 28.1. My overall mileage has predictably suffered since I started wfh full time because I no longer have a nice long highway stretch and more of my trips are very short. I'm still happy with my fuel economy since my car (98 Accord) is rated at 20/27/23. I drive speed limit+ but still conservatively.

    I use a program called Mileage on my phone. I've been keeping data for 2 years for 2 vehicles, my F150 and Grand Marquis. Both are 4.6L motors and 4-speed automatics. Truck has 3.55 ring and pinion ratio and Grand Marquis has 2.73s

    Here's some nuggets

    F-150
    Average MPG: 16.57
    Average distance per tank: 322.56 miles
    Average fill: 19.4 gallons
    Average cost per tank: $67.12
    Average price per gallon: $3.46
    Estimated cost per year: $1088.90


    Grand Marquis
    Average MPG: 22.23
    Average distance per tank: 270.21 miles
    Average fill: 12.09 gallons
    Average cost per tank: $42.04
    Average price per gallon: $3.47
    Estimated cost per year: $1047.51



    EDIT: I tried to get my wife to record her odometer and save her receipts for her S40 but that happened exactly once so I gave up. My parents frequently borrow the Grand Marquis to travel and I force them to save the info.

    I do for the toy, but not my daily driver oddly enough.

    I track dates, odometer, gallons, and fuel price. From those I project my trending year mileage + simple averages, fuel cost per mile etc.

    Car computer is typically 1-2 MPG high in mixed driving and 1-2 MPG low on all highway.

    As for costs I don't really track prices as I always relied on my Discover card spend analyzer for that. Then my number got stolen twice in a year and wiped out my history. Boo

    I don't for my work vehicle, I fill up daily and it's to much like more work. I do use an app to keep track of it with my personal vehicle.

    I did when I first got my car but don't care anymore even though I drive 100 miles a day. Just cant be bothered, its not like I'm going to NOT drive if its bad.


    Computer says 25-26 mpg on a 2004 Mini S with a pulley and intake.

    No -

    its a commuter, almost 17K miles in just 11.5 months of ownership. I fill it up way too often with a 12G tank but have a on board trip computer saying that I've averaged 31.4mpg over 15,500 miles.

    I used to till I forgot to export FuelLog's database once before flashing a rom update. Lost 3 months worth of fillup data. Havent bothered since then. I get around 15 to 16mpg.

    If I'm lucky.

    I do in my 2012 GTI DSG (Stage 1 Tune/Intake). I get around 26mpgs average over the past 4 months I've owned it.

    I drive 54 miles a day for work 5 days a week though, so its mostly all highway. All the little in town driving is what kills my average though, I drive like an old person on my commute and make up for it by being enthusiastic around town.

    I usually check what my average is per tank fillup but I don't write it down. It is pretty consistent.

    I don't much on my Mazda, but it gets about 26 whenever I do.

    My Cobalt figures mileage for me, and I have gotten between 27 and 36 per tank.

    I just track mileage by month and that's it. As long as I get more than 190 miles out of a tank, I don't worry.
