When is driving further worth it?

Only when the cents-per-litre saving is bigger than the fuel burned and time spent on the detour. A 5c/L saving on a 50L fill is $2.50 before the extra kilometres are counted.

Should I apply discount vouchers first?

Compare the base pump price first, then apply dockets, member rates or app locks. A discount off an expensive station can still lose to a cheaper nearby station.

Why do calculator results differ from the bowser receipt?

Fuel economy changes with traffic, towing, tyres, speed and load. Treat the calculator as a planning estimate, then use your car and receipt history to tune the inputs.

Find the cheaper area

Compare areas, cities and fuel networks before choosing a petrol station.

Compare the full cost

Compare fuel grades, discounts and longer-term running costs instead of the board price alone.

Use the tools

Start with a station price, then run the numbers

Check when the price was reported and include any detour. Then choose the calculator that matches your trip.

Fuel saving tips

Before you rely on the result

A calculator is only as good as the station price and distance you put into it.

Check before you fill
Check the map before every fill. A cheaper station only helps when its update time is recent and the detour is still on your route.
Find cheap fuel now
Time the cycle
Use the price cycle when you can choose the day. If prices are near a peak, buy only what you need and compare again as the cycle softens.
See price cycles
Stack discounts carefully
A docket, app lock or member price is only a saving after it beats the cheapest reported station nearby. Compare first, discount second.
Compare discounts
Do the route maths
Use the trip and detour calculators when the cheaper station is off-route. Small cents-per-litre gaps disappear quickly after extra kilometres.

Calculator FAQ

Using fuel calculators with reported prices

Use the reported station price for the exact fuel grade you plan to buy, then check the station update time. A stale cheap row can make a trip or detour look better than it is.
