Fuel Saving Tips
Accuracy with any process is a result of reducing variations between samples. If you want consistent fill-ups, park your car the same way at each fill up. This helps ensure that the gas tank is in the same position each time. A gas tank may have more reservoir in front of the gas tank or the back. Air can get trapped, reducing the amount of area that gas can occupy. Try to park your car the same way and your MPG readings will be more accurate.
