How fuel consumption works
L/100km measures how many litres of fuel your vehicle uses to travel 100 kilometres. A lower number means better fuel economy. You can find your vehicle's rated consumption on the fuel label (often on the driver's side visor) or in the owner's manual. Real-world consumption is usually 10-20% higher than the rated figure.
Tips to reduce fuel costs
Fuel types in Australia
E10 (91 RON + ethanol)
Cheapest option. Contains 10% ethanol. Suitable for most vehicles but slightly lower fuel economy.
91 ULP (Unleaded Petrol)
Standard unleaded. Compatible with all petrol vehicles. Most common fuel type.
95 Premium Unleaded
Higher octane for better performance. Recommended for some European and performance vehicles.
98 Premium Unleaded
Highest octane petrol. Required by some high-performance and turbocharged engines.
Diesel
Used in many SUVs, utes, and commercial vehicles. Generally better fuel economy but higher price per litre.
The formula
Total litres:
(distance / 100) × L/100km
Total cost:
litres × price per litre
Cost per km:
total cost / distance

To calculate the fuel cost of a trip, divide the distance by 100, then multiply by your vehicle's fuel consumption rate (L/100km) to get the total litres needed. Multiply the litres by the price per litre to get the total cost. For example, a 500 km trip at 8.5 L/100km with fuel at $1.75/L uses 42.5 litres and costs $74.38. This calculator handles the maths instantly for any combination of distance, consumption, and fuel price.
L/100km (litres per 100 kilometres) is the standard measure of fuel consumption in Australia. A small city car might use 5-6 L/100km, while a large SUV could use 10-12 L/100km. Your actual consumption depends on driving conditions — city driving with frequent stops uses more fuel than steady highway cruising. Air conditioning, load weight, tyre pressure, and driving style all affect real-world fuel economy.
