Fuel Range Calculator
Estimate vehicle driving range from tank size, current fuel level, reserve fuel, and fuel efficiency.
FormulaRange = usable fuel / efficiency x 100
Formula
Fuel range formula
Actual range depends on traffic, terrain, load, air conditioning, weather, tire pressure, and driving style.
Range = usable fuel / efficiency x 100
A 50 L tank at 60% with 5 L reserve and 7 L/100 km gives about 357 km usable range.
