How it works
How it works: consumption = liters ÷ kilometers × 100 (L/100 km); efficiency = kilometers ÷ liters (km/L); trip cost = liters × price; cost per km = cost ÷ kilometers. Measure between full refuels for best accuracy.
Frequently asked questions
How do I measure real consumption?
Fill the tank, note the km, drive normally, fill again: divide refueled liters by km and multiply by 100.
Why does it use more in the city?
Starts, traffic lights and idling: urban consumption can be 30-50% higher than steady highway driving.
How do I lower consumption?
Correct tire pressure, steady speed, remove useless trunk weight and avoid jackrabbit starts: you can save 10-15%.
