How does FuelRadar make the forecast?
FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Melbourne'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. These are Melbourne city averages, not a separate Grantville forecast. The likely range widens with each day ahead.
Next-day estimates missed by 0.9 c/L on average over the 30 days to 14 Nov, closer than assuming prices stay the same (1.0 c/L).

Estimate only: Premium diesel in Grantville is estimated to edge down about 2.8 c/L, to 263.9 c/L by Mon 23 Nov (likely 252.1–283.5), from 266.7 c/L reported Mon 16 Nov. 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 Grantville?
There is no fixed best day for Grantville. 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 16 Oct to 14 Nov our next-day Premium diesel forecasts for Melbourne were off by 0.9 c/L on average over 30 days checked. That beat assuming prices wouldn't move (1.0 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.
