What is the best day to buy Premium diesel in Rockville?
There is no fixed best day for Rockville. 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 Toowoomba were off by 0.6 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.
How often is the outlook updated?
We update the forecast overnight. For anything that changed today, check the map. While the update runs, we may show the previous forecast with its date.
