When is the best day to buy petrol in Adelaide?

Across Adelaide, the better buying window depends on where the local price cycle sits, not a fixed weekday. Check whether prices are rising or easing, then compare nearby station prices and update times before a large fill.

How many stations have reported prices in Adelaide?

Before you choose a station

Service stations in Adelaide can change prices during the day, so the city average is a guide rather than a bowser price. The reported unleaded 91 average is 198.1 c/L, and the lowest report is 9.4c/L below it. Check the station update time and distance before travelling for the difference.

Choose the fuel type your vehicle uses, compare stations within the distance you are willing to drive and check when each price was reported. Use a station on your normal route unless the price difference covers the extra travel. Brands reporting in Adelaide include Costco, Mobil, Independent. Compare individual stations because a brand average can hide local differences.
