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.

Use the tools
Start with the price, then calculate the decision
Most calculator mistakes come from using a stale price or ignoring the detour. Start with a reported station row, then choose the calculator that matches the trip.
Fuel saving tips
Turn the numbers into a cheaper fill-up
The practical habits that make the calculators useful before you leave.
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 cyclesStack 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 discountsDo 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
Short answers before you rely on a cents-per-litre saving.
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.
