PetrolSpy shows you the cheapest station near you right now. That is useful. But the bigger saving often comes from when you fill up, not where.
PetrolSpy is a community-driven fuel price app. It relies on users reporting prices, which means coverage is good in high-traffic areas and thinner elsewhere. It is useful for comparing nearby stations at a point in time.
PetrolSpy does not track price cycles. It does not tell you whether prices are near a low point or about to spike. It does not predict when the cheapest time to fill up will be.
Knowing the cheapest station today is helpful. Knowing that today is the cheapest day in the cycle — that is where the real savings are.
Fixr uses government fuel price data to track where each city sits in its current price cycle. Instead of showing you today's cheapest station, it tells you whether today is a good day to fill up.
Fixr sources prices from government APIs — FuelCheck NSW, FuelPricesQLD, FuelWatch WA, Fair Fuel VIC, and others. Data is mandatory-reported and regularly audited.
The gap between the cheapest and most expensive day in a fuel price cycle is about 15 cents per litre. Fixr helps you fill up closer to the low. Same station, same fuel — different timing.
