How we forecast
FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Sydney'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 Sydney Premium diesel outlook, adjusted by 7.4 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, closer than assuming prices stay the same (0.5 c/L).

Forecast questions

Estimate only: Premium diesel in Menai is estimated to change little, to 275.8 c/L by Sat 21 Nov (likely 265.7–294.7), from 275.8 c/L estimated for Sat 14 Nov. Past 7-day estimates missed by about 4.5 c/L on average, only slightly less than assuming prices stay the same (4.7 c/L). The dated 30-day forecast shows a likely range, not a promised low date. Check current station prices before changing when you fill.
What is the best day to buy Premium diesel in Menai?
There is no fixed best day for Menai. 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 Premium diesel 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 Premium diesel forecasts for Sydney were off by 0.4 c/L on average over 30 days checked. That beat assuming prices wouldn't move (0.5 c/L).
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.
How often is the outlook updated?
We update the forecast overnight. For anything that changed today, check the map.
