WA Metro Petrol Price Trends and Key Movers This Week

Metro U91 didn't drop in a straight line this week. Prices actually crept up from 154.3c on Monday to a mid-week peak of 158.6c on Wednesday, before sliding back down to close the week at 150.8c on Sunday. If you filled up mid-week without checking, you paid around 8 cents more per litre than those who waited.

Metro diesel told a cleaner story, falling steadily every single day from 179.2c on Monday down to 169.2c by Sunday. That's a consistent, uninterrupted drop across seven days.

P95 followed a similar mid-week bump pattern to U91, peaking at 174.1c on Wednesday before easing to 165.9c by Sunday. P98 did the same, touching 182.8c mid-week before retreating to 175.0c.

At 190.5c/L for U91 and 217.2c/L for diesel, regional drivers are paying 36 cents and 44 cents more per litre respectively than their metro counterparts. For anyone doing a 60-litre fill, that's roughly $22 to $26 more every single time.
