How to Calculate Fuel Efficiency

Calculating your vehicle's fuel efficiency is a straightforward process that helps you understand how far you can travel on a specific amount of fuel. The most common metric in the United States is Miles Per Gallon (MPG). To find this, you simply divide the total number of miles driven by the total number of gallons of fuel used during that trip.

Understanding MPG vs. L/100km

While MPG is standard in the US, many other countries use Liters per 100 kilometers (L/100km) or Kilometers per Liter (km/L). It is important to note that these metrics are inversely related. A higher MPG is better (more distance for less fuel), whereas a lower L/100km is better (less fuel to cover a fixed distance). This calculator provides all three metrics so you can understand your car's performance regardless of the measurement system.

Tips to Improve Your Fuel Economy

Improving your fuel efficiency saves money and reduces your environmental footprint. Here are a few quick tips:

  • Maintain Tire Pressure: Under-inflated tires increase rolling resistance.
  • Drive Smoothly: Avoid rapid acceleration and hard braking.
  • Reduce Weight: Remove unnecessary heavy items from your trunk.
  • Regular Maintenance: Keep your engine tuned and air filters clean.
