How it works

MPG = miles driven / gallons used. Miles driven = current odometer − last fill-up odometer. Record both values at every fill-up for accuracy. L/100km = (liters used / km driven) × 100—note this is inverse to MPG (lower is better). Fuel economy varies 20–30% between city and highway driving. Monitor trends to catch engine or tire issues early.
