Quick verdict

Use Petrol Spy when you want a simple, familiar fuel map for Australia or New Zealand and you already like its app workflow.

FuelRadar vs Petrol Spy at a glance

Where Petrol Spy is strong

Petrol Spy is a known fuel-price map for Australia and New Zealand. Its public pages promote a free fuel app, nearby map searches, user-reported or FuelWatch-labelled prices depending on location, and historical U91/E10 cycle graphs. If your main job is to open a map and find a nearby station quickly, it can be a useful option.

How this comparison was checked

Last checked: 8 July 2026. This page compares public workflows shown on Petrol Spy and its App Store listing against FuelRadar map, city, suburb, station, forecast, calculator and guide pages. Feature claims are based on those public pages, not private access or paid data.

Where FuelRadar is stronger

FuelRadar is designed around the full fill-up decision. A low price is not enough by itself; drivers also need to know whether the fuel grade is right, whether the update is recent, how far the detour is, whether nearby suburbs are cheaper, and whether the city is near a price-cycle high or low. That is why FuelRadar pairs the map with city pages, suburb pages, station pages, price-cycle pages, forecasts, reports and calculators.

The practical saving test

A 6c per litre saving is worth about $3 on a 50-litre fill. If the cheaper station is on your route, take it. If it is across town, the saving can disappear in extra distance and time. FuelRadar is stronger here because it makes the driver compare the price with distance, update time and local spread before choosing.

Which should you use before driving?

If you are standing near the car and only need a quick price map, either tool can help. If the cheapest station is more than a short detour away, use FuelRadar to check update time, distance, local spread and cycle context before committing. The practical question is not "which app has the lowest number?" It is "which station is cheap, recently checked, nearby and worth the drive?"

Data and update-time reality

No fuel-price service is perfect in every suburb or state. Coverage depends on government reporting programs, retailer feeds, station participation and community or partner updates. Before a long detour, always check the fuel grade, the station address and the update time. If a price looks unusually low, compare nearby stations and consider whether it may be stale or tied to a specific fuel grade.

Best workflow if you already use Petrol Spy

Keep Petrol Spy if it gives you useful nearby map results. Add FuelRadar when you need an answer beyond the nearest cheap dot: whether to fill now, which nearby suburb is cheaper, how much a detour really saves, what the station update time says, and whether the city cycle suggests waiting. For most motorists, that makes FuelRadar the stronger place to start.
