How to calculate your fuel economy.

  1. Fill your tank
  2. Reset the trip meter.
  3. Drive vehicle several hundred miles
  4. Refill the tank.
  5. Take the number of miles driven divided by the number of gallons at that fill up.

For instance, you fill your tank. Then drive 250 miles. Then you refill your tank and add 13.8 gallons of fuel.  250/13.8=18.1 miles per gallon.
You can do this over several tanks to get an average. You can also tell if you fuel mileage improves or goes down.
