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?

FuelRadar Australia lists reported prices at 172 stations across Adelaide, using available state reporting, retailer and station data.

Is it worth driving to a cheaper suburb in Adelaide?

Multiply the price difference by the litres you expect to buy, then compare that gross saving with the return distance, fuel used and time. A cheaper station already on your route needs less saving to make sense than a special trip across Adelaide.

Compare the reported price, update time and distance before choosing a station in Adelaide.

172 stations across 8 fuel types are included in Adelaide, SA. Check the report time and use the map for distance before you drive.

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 premium diesel average is 243.1 c/L, and the lowest report is 14.4c/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, Shell. Compare individual stations because a brand average can hide local differences.

Is a detour around Adelaide worth it?
