When is fuel cheapest in Adelaide?
Adelaide's price cycle is paused, with no regular price jumps lately (the last jump started Fri 18 Sept): its U91 prices are following wholesale costs and the recent trend, so they tend to move a week or two after the terminal gate price.
On Fri 6 Nov the national terminal gate (wholesale) price was 211.5 c/L and the Adelaide city average 224.3 c/L, 12.8 c/L above it.
No weekday was the cheapest in most of the last 12 full weeks to : the U91 weekday averages in Adelaide were within 0.4 c/L of each other once the overall price movement is removed.

How we forecast
FuelRadar has helped Australian drivers find cheaper fuel since 2020. Each estimate starts from Adelaide'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 Adelaide U91 outlook, adjusted by -5.1 c/L using local price history. The likely range widens with each day ahead.
Next-day estimates missed by 0.7 c/L on average, no better than assuming prices stay the same (0.7 c/L).

Forecast questions
When will U91 prices go down in Klemzig?
Estimate only: U91 in Klemzig is estimated to edge down about 5.3 c/L, to 201.1 c/L by Fri 20 Nov (likely 190.9–218.8), from 206.4 c/L estimated for Fri 13 Nov.

Check current station prices before changing when you fill.
What is the best day to buy U91 in Klemzig?
There is no fixed best day for Klemzig. 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 Adelaide were off by 0.7 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.
