How fuel cost is calculated

Fuel cost is calculated by converting your vehicle's fuel consumption rate and trip distance into litres consumed, then multiplying by the current fuel price per litre.

Typical fuel consumption (Australia)

  • Small car / hybrid: 5–7 L/100km
  • Mid-size car: 8–10 L/100km
  • SUV / 4WD: 10–14 L/100km
  • Ute / large vehicle: 12–18 L/100km

Tips to reduce fuel costs

  • Maintain correct tyre pressure — under-inflation increases fuel use by up to 3%
  • Remove unnecessary weight from your vehicle
  • Use cruise control on highways to maintain constant speed
  • Find cheaper fuel using GasBuddy or MotorMouth apps

Carpooling: Use the passenger split feature to see how much you save by sharing the trip. Splitting a $50 fuel cost between 3 people saves $16.67 each vs driving separately.
