Frequently Asked Questions
How do I calculate MPG?
Fill your tank completely, reset your trip odometer, drive normally, then fill up again. Divide miles driven by gallons added: MPG = Miles Driven / Gallons Used. For accuracy, do this over several fill-ups.
What is good MPG for a car?
As of 2024, the average new car gets about 27 MPG combined. Over 30 MPG is considered good, over 40 MPG is excellent. Hybrids often achieve 45-60 MPG and electric vehicles have MPGe ratings of 90-130+.
Why is my actual MPG different from the EPA rating?
EPA tests are done under controlled conditions. Real-world MPG varies based on driving habits (aggressive driving lowers MPG 15-30%), weather, terrain, tire pressure, vehicle load, and air conditioning use. City driving is less efficient than highway.
