How we forecast
FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Toowoomba's reported daily city averages and how they have moved recently. A city daily average is FuelRadar's scheduled morning average of the city's reported station prices, the figure this page quotes for every capital. Where a city has a regular price cycle, the estimate projects that cycle; elsewhere it follows the recent trend, blended with the latest dated wholesale price change. Based on the Toowoomba U91 outlook, adjusted by -3.3 c/L using local price history. The likely range widens with each day ahead.
Next-day estimates missed by 0.4 c/L on average, no better than assuming prices stay the same (0.5 c/L).

What is the best day to buy U91 in Harristown?
There is no fixed best day for Harristown. Compare current reported station prices and their update times. A recent high or a lower estimate does not confirm a cheaper date.
How accurate is FuelRadar Australia's U91 price outlook?
Not accurate enough yet to tell you to fill or wait, so we don't. From 10 Oct to 8 Nov our next-day U91 forecasts for Toowoomba were off by 0.4 c/L on average over 30 days checked. Assuming prices wouldn't move was just as close.
Do higher prices mean they will fall soon?
A recent high does not confirm a turnaround. Compare the reported movement with the estimated range. If that range still includes today's price, a fall is not established. Check current station prices before deciding to wait.
