SA Fuel Prices – Week of 1 June 2026

South Australian drivers caught a genuine break this week. Metro U91 dropped 10c to land at 163.2c/L, marking the fourth consecutive week of falls and placing SA as the cheapest state in the country. That's not a minor dip — that's real money back in your wallet.

SA Fuel Prices Snapshot: 1–8 June 2026

Biggest Movers in SA Petrol Prices This Week

Diesel led the charge with a 11.4c metro fall, bringing it to 205.4c/L. That's a meaningful saving for tradies and freight operators, though the gap between diesel and U91 remains wide at 42.2c/L — still something to keep an eye on if you're running a diesel vehicle.

U91's four-week slide is the story of the month. The current metro price of 163.2c/L is sitting very close to its 30-day low of 152.5c/L, which tells you we're near the bottom of the current cycle — not the top.

P98 and P95 both shed around 10c in metro areas, landing at 187.9c/L and 179.3c/L respectively. If you've been holding off on a premium fill, this week's pricing is relatively favourable.

E10 remains the cheapest option at 158.7c/L metro, though availability is limited to just 31 metro stations. Worth checking the app before you make a special trip.

The daily trend data tells a consistent story: prices fell steadily from Monday through Saturday, then flattened out. U91 metro opened the week at 169.3c/L on 1 June and eased to 159.4c/L by the 6th, where it held firm.

Rural vs Metro: What the Gap Actually Costs SA Drivers

Rural SA drivers saw falls too, but the gap remains punishing. Country drivers are paying 188.5c/L for U91 compared to 163.2c/L in metro areas — a 25.3c/L difference. Fill up a 60-litre tank and that's over $15 more per visit just because of where you live.

Cheapest Metro Stations and Brand Averages in SA

There's a big spread between metro stations this week. The cheapest recorded was 152.5c/L and the most expensive was 199.9c/L — a jaw-dropping 47.4c/L gap. That's the difference between a bargain and getting stung, and it's entirely avoidable if you check prices before you drive.

On the brand front, U-Go averaged 159c/L and SOLO came in at 159.8c/L, while BP and some independents averaged 170.5c/L. That's an 11.5c/L gap between the cheapest and priciest brands, which adds up fast if you're filling up weekly.

Last Week's Cheapest Fill-Up Day

Last Sunday (7 June) was the cheapest day to fill up metro U91 at 159.4c/L. Prices had been drifting lower all week, so those who waited it out were rewarded.

SA Metro Petrol Price Forecast: Next 3 Days

The outlook for metro SA looks encouraging. U91 is forecast to ease from the current 163.2c/L down to 157.8c/L on 8 June, 156.7c/L on 9 June, and 155.5c/L on 10 June. Confidence sits between 65% and 78%, so it's not a certainty, but the trend is pointing downward.

How to Save on Fuel in SA This Week

If you're in metro Adelaide and your car runs on E10, that's your best bet right now at 158.7c/L. On U91, shopping around between brands could save you more than 11c/L compared to just pulling into the nearest station. Rural drivers should fill up whenever they're passing through a larger town — waiting rarely helps when you're remote. And nationally, SA is sitting 8.8c below the national metro average of 172c/L, so the state is well-placed right now.
