Frequently Asked Questions
How do I calculate my actual fuel consumption?
Fill up completely, note the odometer reading, drive until near empty, fill up again and note the liters. Divide liters by kilometers driven, then multiply by 100 to get liters per 100 km.
How can I reduce my fuel consumption?
Drive at moderate speeds, shift early (around 2,000 RPM for diesel, 2,500 for gasoline), check tire pressure regularly, remove roof racks when not in use, and avoid short trips with a cold engine.
What is the Fuel Consumption Calculator?
The fuel consumption calculator computes fuel consumption per 100 km and the fuel costs of a trip or over a period.
How does the Fuel Consumption Calculator work?
Enter the distance driven and the fuel amount filled. The calculator determines consumption in litres per 100 km. With the current fuel price the cost per kilometre and per trip is computed.

Step-by-Step Guide
How to calculate den Spritverbrauch step by step: 1. Tankfuellung notieren: Tanken Sie voll und merken Sie sich den Kilometerstand. 2. Naechste Tankfuellung: Beim naechsten Volltanken notieren Sie den neuen Kilometerstand und die getankte Menge in Litern. 3. Gefahrene Strecke: Neuer Kilometerstand minus alter Kilometerstand. 4. Verbrauch calculate: (Getankte Liter / gefahrene km) x 100 = Liter pro 100 km. 5. Spritkosten pro km: Verbrauch pro 100 km / 100 x Literpreis. 6. costs pro Fahrt: Strecke x costs pro km. 7. Tipps zum Spritsparen: Reifendruck regelmaessig pruefen (0,3 bar ueber Norm spart ca. 3 %). Vorausschauend fahren, Motor nicht warmlaufen lassen. Kurzstrecken vermeiden. Klimaanlage bewusst einsetzen. Eco-Fahren spart 10-20 % Kraftstoff.
Calculation Example
Getankt: 45 Liter, gefahren: 580 km. Verbrauch: 45 / 580 x 100 = 7,76 l/100 km. Bei Benzinpreis 1,70 EUR/l: costs pro km = 0,132 EUR. Fahrt 250 km: 32,93 EUR.
