The single biggest saving in NSW fuel isn’t timing the market. It’s the gap between two stations a few minutes apart, which regularly reaches 20 to 40 cents a litre. On a 50-litre tank that’s $10 to $20, every fill, no forecasting required.
Where the spread comes from
Every station pays roughly the same wholesale price and exactly the same tax. The difference is the retail layer:
- Where a station sits in the price cycle. Stations don’t move together. During the discounting phase, one station cuts today, its neighbour cuts on Thursday. Catch the one that cut first.
- Brand strategy. Some brands price to the top of the market and rely on location, loyalty dockets, or convenience. Independents more often price to move volume.
- Site costs. A motorway service centre pays motorway rent and prices like it. The same brand’s suburban site down the ramp doesn’t.
- Local competition. A station with three rivals in sight behaves differently from one with a captive corner.
What the spread means in practice
- Never fill up without checking one screen first. The spread is visible in advance; petrol is one of the few things you can comparison-shop in real time with government data.
- Don’t drive far for it. A 20-cent saving on 40 litres is $8; a 15-minute round trip can burn a litre or two and your time. The win is picking the best of the stations already on your route.
- The spread persists in every phase of the price cycle. Even on the most expensive day of a spike, the cheapest nearby station is still well under the dearest one.
