Fuel planning guide

Check the result against local prices

Use a recent reported price from a nearby station. Check its update time and include any extra distance in your estimate.

A calculator is only as good as the pump price you enter. Check nearby stations first, then run the numbers with a realistic local price.

If this route is part of your normal week, multiply the result by your usual trips and compare it with the monthly budget calculator.

A cheaper station is not always cheaper after extra distance. Use the detour calculator when the saving is only a few cents per litre.
