Fuel Consumption Calculator
Enter the distance, average consumption and price per litre to see the fuel cost of your trip.
This tool estimates trip fuel cost from the distance, consumption and price per litre you enter. Actual costs vary with traffic, road conditions and driving habits, so treat the result as an approximation.
How Is Vehicle Fuel Consumption Calculated?
Fuel consumption is given in litres per 100 km (L/100km). Formula: Consumption = (Fuel used ÷ Distance) × 100. Example: 35 litres over 500 km gives 35 ÷ 500 × 100 = 7 L/100km.
Total trip cost: Cost = (Distance × Consumption ÷ 100) × Price per litre. Example: for 450 km, 7 L/100km and 45 TL/litre, (450 × 7 ÷ 100) × 45 = 1,417.50 TL. The calculator does this for you.
How to Use the Fuel Consumption Calculator?
The calculator has three modes. For cost, enter distance (km), average consumption (L/100km) and price per litre to see the total fuel cost. For distance, enter the amount you paid, your consumption and the price per litre to see how far you can go. For your car's real consumption, enter what you paid and the distance covered; add the price per litre to see litres per 100 km.
What Factors Affect Vehicle Fuel Consumption?
Fuel consumption is not fixed. Driving style is the biggest influence: sudden acceleration and hard braking can increase consumption by 20–30%. Frequent city stops use far more fuel than steady highway cruising. Tyre pressure, air conditioning use, vehicle load, hilly routes and engine maintenance also directly affect consumption.
Factory consumption figures are measured under ideal conditions. In daily use, real consumption can be 10–25% higher, so entering your own average rather than the factory figure gives a more accurate result.
Fuel-Saving Tips Before Your Journey
Check tyre pressure: each 0.1 bar below the recommended level increases consumption by around 0.5%. Using cruise control on long journeys saves fuel. At low speeds, open windows are more efficient than air conditioning; at highway speeds the reverse is true. Removing unnecessary luggage and weight, and taking off roof racks or spoilers when not in use, also reduces consumption. Finally, planning your route in advance to avoid traffic saves both time and fuel.
Practical Driving Tips to Save Fuel
Keeping tyre pressure at recommended levels, maintaining a steady speed and avoiding sudden braking or acceleration can reduce fuel consumption by 10–15%. Using the air conditioning less and removing unnecessary loads from the vehicle also help. Regular servicing and a clean air filter maintain engine efficiency and help lower fuel costs.
Difference Between City and Highway Fuel Consumption
In city driving, fuel consumption can be 25–30% higher than on the highway because of stop-and-go traffic, congestion and low speeds. This is why manufacturers usually publish two different consumption figures. To measure your actual consumption, simply record the odometer reading before filling up and the amount of fuel added afterwards.
