MotorMouth vs FuelRadar: quick answer

Start with FuelRadar when the job is choosing where to fill up in Australia. FuelRadar has been helping Australian drivers since 2020: it reads the official price program in every state and territory, shows when it last updated each price, and adds 7-day city estimates, free price alerts and a detour check. MotorMouth is a free app for iPhone and Android with a colour-coded map, brand and fuel filters, a best-time-to-buy view, and market trends and price history for your area.

Who publishes this comparison

FuelRadar publishes this guide and has an obvious interest in the result. We compared MotorMouth's public website and App Store listing with FuelRadar against the same driver tasks: finding your fuel type, seeing how recent a price is, deciding when to fill, getting an alert and checking whether a cheaper station is worth the drive. Where MotorMouth has a clear strength, it is stated plainly.

Colour-coded map vs a price with its update time

MotorMouth colour-codes sites so the cheapest in an area stand out, and one tap shows the price. FuelRadar lists the price for your fuel type at each station, ranked, with the time FuelRadar last updated it, so a recent price is easy to tell from an old one. Both let you filter by fuel type and brand.

Best time to buy and price history

MotorMouth's listing says it shows whether now is the best time to buy, with market trends and price history in your area. FuelRadar publishes a 7-day estimate for each capital city, a daily city average chart with each cycle's recent low, and a replay that shows how far past estimates were from what prices did. Treat any timing call as guidance and check the station before a big fill.

Calculators and the return detour check

A cheaper price only saves money if the extra drive does not eat it. FuelRadar's free detour check takes the price gap, litres, return distance and your car's fuel use; its trip-cost, fill-up and route planner tools are free too. We did not find a detour or trip calculator on MotorMouth's website or app listings.

Apps, alerts and cost

MotorMouth is free for iPhone and Android; on 28 September 2026 both listings showed an update from April 2026, and the Google Play listing shows digital purchases. FuelRadar has free iPhone and Android apps and the full website. A free FuelRadar account holds 2 price alerts and 25 saved stations; FuelRadar+ adds more alerts and no website ads while signed in.

Which service should you use?

Use MotorMouth if you already like its colour-coded map and best-time-to-buy view, or want to update prices for other drivers. Use FuelRadar when you want the exact price for your fuel type with its update time, a dated 7-day estimate, free alerts and the detour maths. Either way, confirm the price on the bowser before you fill.
