NSW Fuel Prices – Week of 20 July 2026

NSW drivers copped another sting this week. Metro U91 climbed 9.2 cents to land at 179.6 c/L, marking four consecutive weeks of rises, and the pain was felt right across the fuel board, with every fuel type pushing higher.

NSW Fuel Prices This Week: Metro vs Rural

Biggest Movers in NSW Petrol Prices This Week

Diesel was the standout, jumping a brutal 20 cents in metro areas to 219.4 c/L. That's a premium of 39.8 cents over metro U91, which is notably wide and will be hitting tradies and anyone running a diesel vehicle hard right now.

U91 climbed steadily through the week without pause, opening at 174.5 c/L on Monday and finishing at 184.8 c/L by Sunday. There wasn't a dip or reprieve in sight, just a straight, unrelenting climb every single day.

E10 followed a near-identical path, rising from 172.5 c/L on Monday to 183.0 c/L by Sunday, making it the cheapest fuel option available in metro NSW this week at a weekly average of 177.7 c/L.

P95 and P98 premium grades both tracked the same upward trajectory, with P95 closing the week at 202.9 c/L metro and P98 reaching 210.4 c/L by Sunday.

Compared to the rest of the country, NSW is actually sitting 2.6 cents below the national metro U91 average of 182.2 c/L, which is a small consolation given how quickly prices have risen.

How Much Prices Vary Across NSW Metro Stations

The range between the cheapest and most expensive metro stations this week was striking. Metro Fuel Metro Petroleum Epping came in at 158.9 c/L for U91, while BP Loftus was charging 199.9 c/L, a gap of 41 cents per litre. On a 50-litre fill, that's a $20.50 difference depending on where you stop.

Brand averages tell a similar story. Arko Energy averaged just 170.8 c/L across its 3 metro stations, while BP averaged 184.0 c/L across 90 stations. That's a 13.2 cent gap, which adds up fast if you're filling up weekly.

Last Week's Cheapest Day to Fill Up in NSW

Last Monday (20 July) was the cheapest day to fill up, with metro U91 sitting at 174.5 c/L. Every day that followed was more expensive than the last, so anyone who held off waiting for a dip missed the window entirely.
