Petrol Spy vs FuelRadar for Australian drivers: use FuelRadar to compare the exact fuel grade, update time, distance and detour cost before filling.
Quick comparison
Select the exact fuel grade, compare nearby prices, check the update time and work out whether the detour pays. Petrol Spy may help when you need New Zealand stations or want a second check on an unusual Australian price.
Use the ranked list when several station markers are close together, then open the station page for its address, available fuels and directions.
Petrol Spy provides AU/NZ map and list checks, Unleaded notifications and cycle graphs. Use it for New Zealand or to double-check an unusual Australian price, then compare the exact grade, update time, distance and detour in FuelRadar.
For an Australian fill, use FuelRadar to check the fuel grade, reported price, update time, distance and detour cost before choosing a station.

Using this guide
Check the station price, report time and distance before changing your route.
Both services put fuel prices on a map. Petrol Spy also offers a full-screen list, best-time notifications and Unleaded and E10 cycle graphs. FuelRadar links its map and ranked list to local price pages, station report details and detour tools. That difference matters when you are choosing a specific Australian station rather than only spotting a low marker.
In FuelRadar, search a suburb or postcode, select the fuel your vehicle uses and compare the ranked station list with the map. Open a station to check its address, available fuels and directions. Where the source supplies an update time, use it to judge how recent the report is. A low marker is not useful if it belongs to another grade or the extra drive costs more than the pump saving.
Petrol Spy advertises best-time and price-spike notifications for Unleaded, plus historical Unleaded and E10 cycle graphs for listed Australian cities. FuelRadar provides city cycle guidance, forecast pages, local price pages, saved stations and price alerts. Treat timing information as guidance, then choose a station using a current report for the exact grade your vehicle needs.
A 6c per litre gap changes a 50-litre fill by $3 before travel costs. If the cheaper station is already on the route, that difference may be worthwhile. A cross-town detour can use part or all of the saving in fuel and time. FuelRadar trip, detour, fill-up and running-cost tools let you enter the return distance, vehicle consumption and litres needed rather than choosing from cents per litre alone.
Fuel-price coverage varies by suburb, state and fuel type. It can depend on government reporting programs, retailer reports, station participation and community reports. Neither service can guarantee that every grade at every site was updated at the same moment. If a result looks unusual, compare neighbouring stations or make a second check, then confirm the address, fuel grade and displayed price at the bowser.
Last checked: 16 August 2026. We reviewed the public Petrol Spy website and App Store listing, then compared those published features with FuelRadar map, list, city, suburb, station, forecast, alert and calculator pages. The check covers public features rather than private account data or paid API access. Features and coverage can change, so check each service for its current details.
Start with FuelRadar. Choose the exact fuel grade, compare nearby station prices and update times, then check whether the distance and detour still make the lower price worthwhile.
