Car Fuel Tank Range Calculator
Car Fuel Tank Range
Calculate your vehicle total driving range, cost per mile, and remaining range based on fuel tank size, MPG, and current fuel level.
Formula
Combined MPG = 1 / (City% / City MPG + Highway% / Highway MPG); Total Range = Tank Size x Combined MPG; Cost Per Mile = Fuel Price / Combined MPG
Frequently Asked Questions
How is combined MPG calculated?
Combined MPG uses a harmonic mean weighted by driving mix. For 60 percent city and 40 percent highway, it accounts for the lower efficiency of city driving proportionally.
How far can I drive on empty?
Most vehicles can travel 30 to 50 miles after the fuel light turns on, but this varies widely by vehicle. Running on empty can damage the fuel pump and should be avoided.
Does driving style affect range?
Aggressive acceleration, high speeds, and frequent braking can reduce fuel economy by 15 to 33 percent. Smooth, steady driving at moderate speeds maximizes your range.
