MileageMeter

MileageMeter keeps track of the gas/fuel mileage of your car, motorcycle or truck. Every time you re-fill your tank just record the odometer reading, the amount of gas and the price. From this data MileageMeter will calculate your gas mileage and a lot of other statistics like price per mile, average distance driven per day, most miles with one tank, approximate next refill, etc. 

MileageMeter allows you to maintain the gas mileage for up to 20 vehicles and makes it possible to switch between MPG and liters/100km. A number of charts help you to monitor your gas mileage and the gas price over time. MileageMeter includes an export/import function to most spreadsheet programs, so you can use historical data you have already collected.
