Live price data has changed the game
You no longer have to drive around guessing. In several states, petrol stations are required to report their prices in real time, and that data feeds live maps and apps. In New South Wales it comes from the FuelCheck scheme, and in Western Australia from FuelWatch. Both let you see current prices at stations near you before you leave home.
EnergySorted has a live cheapest-fuel-near-you map for NSW and WA built on this data, so you can find the lowest price for your fuel type close to you without hopping between apps. Because prices can swing by 30 to 50 cents a litre across a single city on the same day, checking before you fill is one of the highest-value minutes you can spend.
How to actually find the cheapest fuel
- Check a live price map or app for your area and filter to your fuel type — E10, unleaded 91, 95, 98 or diesel.
- Sort by price, but weigh in the detour: a station 15 cents cheaper across town can cost more in fuel and time than it saves on a small fill.
- Note the day in the price cycle if your city has one — filling near the bottom of the cycle beats filling at the top by a wide margin.
- Fill up properly when prices are low rather than topping up small amounts at whatever the price happens to be.
- Combine the cheap fill with a trip you were making anyway so the detour costs nothing.
Watch the traps
The lowest advertised price is not always the best deal once you factor in distance. A useful rule of thumb: a saving is only real if the extra driving to reach it costs less than the difference. For a 50-litre fill, even a few cents a litre adds up, but for a quick top-up the maths flips.
Loyalty and shopping-docket discounts of a few cents a litre are worth using, but do not let a small locked-in discount keep you at a station that is 20 cents dearer than one down the road. The base price matters far more than the discount stacked on top.
Habits that beat any single cheap fill
Finding the cheapest station helps, but how you drive and maintain the car compounds over the year. Correct tyre pressure, a lighter load, smooth acceleration and not idling all improve fuel economy measurably. Using the right fuel for your engine — rather than needlessly buying premium — also keeps costs down without any loss.
Together, checking live prices before you fill and driving efficiently will save more than chasing the occasional bargain across town. Set the habit of a quick price check, and let the map do the searching for you.
