Fuel Efficiency Calculator

Accurately estimate your vehicle's MPG or L/100km and fuel costs with our easy-to-use calculator.

Calculate Your Fuel Efficiency

Understanding Your Fuel Efficiency

Your vehicle's fuel efficiency tells you how effectively it uses fuel over a certain distance. Two common measurements for fuel efficiency are miles per gallon (MPG) and liters per 100 kilometers (L/100km):

  • MPG (Miles per Gallon): Indicates how many miles your vehicle travels using one gallon of fuel. A higher MPG means better fuel efficiency and lower fuel costs.
  • Liters per 100 km (L/100km): Indicates how many liters of fuel are consumed per 100 kilometers traveled. A lower L/100km means better fuel efficiency and reduced costs.

By entering the distance you traveled and the fuel you used, the calculator quickly shows your efficiency in whichever metric you prefer. This information is critical for tracking changes in your fuel consumption over time, especially if you make adjustments like tire pressure or driving habits.

How to Interpret Your Results

  1. MPG: A good MPG depends on vehicle type, road conditions, and driving style. For example, compact cars often average 25–35 MPG in mixed driving, whereas larger SUVs or trucks may get 15–25 MPG.
  2. L/100km: Fuel-efficient cars might see 4–6 L/100km, while less efficient or older vehicles might be closer to 8–12 L/100km. Knowing your typical range will help you spot irregularities, such as sudden drops in efficiency caused by mechanical issues.

Tips for Improving Fuel Efficiency

  1. Maintain Proper Tire Pressure: Under-inflated tires create more rolling resistance, meaning your engine works harder and consumes more fuel. Check tire pressure at least once a month.
  2. Accelerate Gradually: Sudden starts and stops can dramatically reduce your MPG. Aim for smooth acceleration and avoid slamming on the brakes whenever possible.
  3. Reduce Excess Weight: Extra items in your trunk or cargo area cause your vehicle to work harder. Removing unnecessary weight can immediately improve fuel efficiency.
  4. Keep Up with Regular Maintenance: Replacing dirty air filters, using the correct motor oil, and ensuring spark plugs are in good condition can all boost your vehicle's efficiency.
  5. Plan Your Trips: Combine errands to reduce the number of short trips and cold starts. Once your engine is warmed up, it generally runs more efficiently.
