Frequently asked questions

Fuel saving = (nearest price − cheaper price) × litres ÷ 100. Detour fuel cost = (detour km × 2 round trip × efficiency) × cheaper price ÷ 100. Net saving = fuel saving − detour cost. If net saving is above $0, the detour pays off.

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.

See if the detour is worth it

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