Calculate your vehicle's fuel consumption, fuel cost, and required fuel amount.
Understanding fuel consumption and saving money at the pump
Fuel efficiency (fuel economy) measures how far a vehicle travels per unit of fuel. It's expressed as miles per gallon (MPG) in the US, or liters per 100 km (L/100km) in most other countries. Lower L/100km and higher MPG mean better efficiency. Factors affecting consumption: Driving speed (fuel consumption rises sharply above 90 km/h), air conditioning (adds 5–20% consumption), tire pressure (under-inflated tires increase consumption by 3%), load weight, traffic conditions, and vehicle maintenance. Eco-driving tips: Accelerate and brake gradually, maintain a steady speed, use cruise control on highways, avoid idling for more than 1 minute, keep tires properly inflated, and remove roof racks when not in use. Calculating fuel cost: Multiply distance by consumption rate, then by fuel price. For a 500 km trip in a car using 8L/100km with fuel at €1.80/L: (500 × 8/100) × 1.80 = €72. Electric vs. fuel: For comparison, an EV consuming 20 kWh/100km at €0.25/kWh costs €5 per 100km — vs. €14.40 for an 8L/100km petrol car at €1.80/L. The running cost difference is significant.
Find answers to common questions
Liters per 100 kilometers (L/100km) is the metric fuel consumption unit. It shows how many liters of fuel are consumed to travel 100 kilometers. For example, 6 L/100km means 6 liters consumed per 100 km. Lower values are more economical.
