DetailsCompare fuel types on cost per distance, not price per litre
Use compatible vehicles
Only compare fuels a vehicle can safely use, or compare representative vehicles with clearly stated economy figures.
Enter a price for each fuel
Use current local prices for each grade instead of applying one petrol price to every option.
Use real-world economy
A cheaper fuel per litre can cost more per kilometre if the vehicle burns substantially more of it.
Compare fuel costs only
The comparison excludes purchase price, servicing, insurance, depreciation and other ownership costs.

Fuel-cost comparison questions
Why compare by $/km instead of price per litre?
If your vehicle can use more than one fuel grade, compare the economy it gets on each. A dearer fuel costs less per km only when lower consumption offsets the price difference.
What fuel use should I enter for each fuel?
Enter the real-world economy your car gets on each fuel. Check the trip computer after a tank of each; the more accurate the figures, the more reliable the comparison.
Is the cheapest fuel per litre always cheapest to run?
No. A fuel with a higher pump price can cost less per km if your vehicle uses less of it.
