VIC Fuel Prices – Week of 25 May 2026

Diesel in Victoria had a big week, shedding 6.1 cents per litre in metro areas to land at 230.0 c/L. Unleaded and premium also eased, so if you've been holding off filling up, the timing is getting better.

VIC Fuel Prices This Week: Metro vs Rural Snapshot

Rural drivers are still paying 2.9 cents more per litre than their metro counterparts on U91. Over a 60-litre tank that's nearly $1.75 extra, every single fill.

Diesel Leads the Falls in VIC Petrol Prices

The diesel story this week is a clear, consistent slide. Metro diesel opened Monday at 234.2 c/L and fell almost every day, finishing the week at 225.9 c/L by Sunday. That's a drop of 8.3 cents across just seven days.

Rural diesel followed a similar path, easing from 238.0 c/L to 229.6 c/L over the week. Tradies and freight operators in regional Victoria will feel this one.

U91 metro also trended down steadily, moving from 186.8 c/L on Monday to 182.3 c/L by Sunday. There were no mid-week spikes or reversals, just a clean, gradual decline that kept building momentum toward the weekend.

How Brand Choice Affects What You Pay for VIC Fuel

There's a striking gap between the cheapest and priciest branded fuel in metro Victoria right now. Costco is averaging 173.9 c/L for metro U91, while Caltex sits at 189.9 c/L. That's a 16-cent spread between brands, which adds up to roughly $9.60 on a 60-litre tank.

Apco (175.6 c/L) and Metro (177.5 c/L) are also well below the metro average. Shopping around by brand, not just by location, can make a real difference here.

Individual station prices stretch even further. The cheapest metro station this week was Metro Sunshine at 159.9 c/L, while the most expensive was Astron Langwarrin at an eye-watering 400.0 c/L. That gap of 240.1 cents is a reminder that where you fill up matters enormously.

Last Sunday Was the Cheapest Day to Fill Up

Last Sunday (31 May) was the best day of the week to fill the tank, with metro U91 touching 182.3 c/L. The price had been drifting lower since Monday, so drivers who waited were rewarded.

VIC Metro Petrol Price Forecast: Prices Still Heading Lower

The forecast suggests the downward trend isn't done yet. Metro U91 is tipped to fall to 180.9 c/L on Monday (78% confidence), 180.1 c/L on Tuesday (71% confidence), and 179.5 c/L by Wednesday (65% confidence). All three days sit below the current metro average of 184.6 c/L.

Confidence eases a little as the week progresses, which is normal, but the direction is consistent.

On the national stage, VIC metro U91 at 184.6 c/L is 3.7 cents above the national average of 180.9 c/L, and is the most expensive state in the country this week.

How to Save on Fuel in VIC Right Now

Diesel supply is worth keeping an eye on. 38 diesel stations are currently out of stock across Victoria, up from 36 last week, and LPG shortages are more widespread with 64 stations running dry. It's not a crisis, but if your regular station runs diesel, it's worth checking availability before you make the trip.

Given the forecast, there's a case for waiting until early next week if your tank can hold on. Metro U91 could dip close to 179.5 c/L by Wednesday. Choosing a cheaper brand like Costco or Apco over a premium-priced chain could save you close to $10 per fill on top of that.
