Calculate your vehicle's fuel efficiency and cost per kilometer instantly
Car mileage, also known as fuel efficiency or fuel economy, measures how far your vehicle can travel per unit of fuel consumed. It's typically expressed in kilometers per liter (km/l) or miles per gallon (mpg). Higher mileage means your car is more fuel-efficient, saving you money and reducing environmental impact.

Identify fuel efficiency issues early and reduce unnecessary fuel expenses
Better mileage means lower carbon emissions and a smaller environmental footprint
Sudden drops in mileage can indicate mechanical issues requiring attention
Generally, 15-20 km/l (35-47 mpg) is considered good mileage for most passenger cars. Hybrid and electric vehicles can achieve much higher efficiency. Smaller cars typically get better mileage than larger SUVs or trucks.
Fill your tank completely, reset your trip meter, drive normally until you need to refuel, note the distance traveled, fill the tank again and record the fuel amount. Use these numbers in our calculator for accurate results.
Yes, significantly. Most cars achieve optimal fuel efficiency between 50-80 km/h (30-50 mph). Driving faster increases air resistance and fuel consumption. Each 8 km/h over 80 km/h can reduce fuel economy by about 7%.
Manufacturer ratings are tested under ideal laboratory conditions. Real-world factors like traffic, driving habits, weather, terrain, vehicle load, and maintenance affect actual mileage. City driving typically yields 20-30% lower mileage than highway driving.
Yes, using air conditioning can reduce fuel efficiency by 10-20%. At higher speeds, however, open windows create drag that may consume more fuel than using AC. For city driving under 65 km/h, open windows are more efficient; above that, AC is typically better.
