Fuel consumption

Fuel consumption program will calculate your fuel consumption (l/100 km), the flow of money ($/Km) as needed fuel or money to travel, and how much you will be able to pass on the available fuel or money in your pocket :)
Tips for reducing fuel consumption. Refueling history. Backup/restore data to SDCard or Dropbox.

Fuel consumption with the marks on the fuel gauge in the tank.
Accept the mark division of 1/2, 1/4, 0 (not recommended to drive on an empty tank!).
The method of calculation:
1) When the fuel level indicator needle in line with our mark - zeroes meter distance on the instrument panel.
2) Fill. Write the program in the odometer reading on the instrument panel, the amount of fuel added, and the meter distance (ie how many have passed on our mark).
The mark must be a constant! Fuel consumption is between fill ups. Calculations are approximate. The calculation of fuel consumption begins with the next refueling.
