Gas Mileage Calculator

One easy way to calculate gas mileage is to remember the odometer reading or reset the mileage counter when you fill up your gas tank. Next time, when you fill up you gas tank again, obtain the mileage between the two gas fill up based on the odometer reading or the mileage counter. Then divided the mileage by the gas filled in the second time to obtain the MPG (mile per gallon).

Seven Tips to Improve Your Gas Mileage

  1. Do not drive too fast—The optimal speed for most vehicles is between 50 and 60 miles per hour. Gas mileage normally decreases rapidly above 60 miles per hour.

  2. Inflate the tire properly—Under-inflated tires can lower gas mileage by 0.3% per PSI drop.

  3. Remove the unnecessary weight—Try to remove unnecessary items in your vehicles, especially the heavy ones.

  4. Keep your car in good shape—This includes using the recommended motor oil and changing them as recommended by manufacture, keeping your engine properly tuned, ensuring the oxygen sensor in good shape, etc.

  5. Close the windows when driving—Open windows add extra resistance to the vehicles. Some studies showed that air conditioner is normally more fuel efficient than open windows on highway.

  6. Avoid unnecessary idling—An idling vehicle gets 0 MPG.
