WA Fuel Prices – Week of 6 July 2026

Perth drivers are feeling the pinch this week. Metro U91 has climbed 5.4c to reach 167c/L, marking the second consecutive weekly rise, and the pricier fuel grades have followed suit across the board.

Biggest Movers in WA Fuel Prices This Week

P98 led the rises, jumping 5.8c to 191.7c/L in metro areas. P95 wasn't far behind, up 5.6c to 182.8c/L. U91 added 5.4c, and diesel climbed a more modest 4.2c to 182.4c/L.

The daily data tells an interesting story. Metro U91 started the week at 164.2c on Monday the 6th, pushed up sharply to a mid-week peak of 171.4c on Wednesday the 8th, then pulled back steadily to close the week at 165c on Sunday. Rural prices barely moved by comparison, holding close to 194c to 195.2c throughout the week without any real spike or reversal.

Metro diesel told a different story entirely, drifting almost flat early in the week before a slow, steady grind upward from 181.4c on Wednesday to 184c by Sunday. No sharp swings, just consistent creep.

That 15.4c diesel premium over metro U91 is worth flagging for tradespeople and anyone running a diesel vehicle. It's on the wider side and adds up fast over a full tank.

Metro Price Range: How Much Shopping Around Can Save WA Drivers

The gap between the cheapest and most expensive metro stations this week is striking. Costco Casuarina is averaging 142.7c/L for U91, while at the other end of the scale an independent station in Glen Forrest is sitting at 209.5c/L. That's a 66.8c spread on the same fuel, in the same city.

Brand averages reinforce the point. Burk stations are averaging 154c/L across nine locations, and Solo and Metro Petroleum are both around 158c/L. BP is averaging 173c/L across 74 stations, and independent sites average 176.5c/L. Choosing your brand carefully could save you more than 20c per litre on a fill compared to the priciest options.

Best Day to Fill Up Last Week

Last Monday, 6 July, was the cheapest day to fill up in metro Perth, with U91 averaging just 164.2c/L. If you filled a 60L tank on Monday versus Wednesday's peak of 171.4c, you saved roughly $4.30. Timing matters.

WA Metro Petrol Price Forecast: 13–15 July 2026

The outlook offers a bit of relief. Metro U91 is forecast to ease slightly over the next three days, dropping from the current 167c/L to around 164.7c/L on Monday (66% confidence), 164.6c/L on Tuesday (60% confidence), and 164.4c/L on Wednesday (55% confidence). Those forecasts are for metro WA only, and confidence levels drop as the window extends.

How to Save on Fuel in WA Right Now

Prices may be easing slightly into next week, so if you're not running on empty, it's worth waiting a day or two. WA metro U91 at 167c/L sits 1.5c below the national average of 168.5c/L, which is something, though South Australia remains the cheapest state at 163.4c/L. The current metro price is well within the 30-day range of 136.5c to 216.9c, sitting closer to the lower half, so conditions aren't dire even after two weeks of rises.

The actionable takeaway: use brand and station data to shop around. Paying 176.5c/L at an independent site when Burk stations average 154c/L is a real and avoidable cost.
