When is the cheapest day to buy petrol?

In Sydney, Melbourne, Brisbane, Adelaide and Perth, prices follow a weekly cycle. Tuesday or Wednesday is typically the bottom of the cycle. The "Best days to fill up" panel on the homepage shows the current best day for each city.

Where do FuelRadar Australia prices come from?

Prices come from official state government price portals plus retailer disclosures. Stations are required by law to report price changes within 30 minutes.

Are these prices live?

Prices refresh every 15 to 30 minutes. Always confirm at the bowser before paying — there can be a short delay between a price change at the station and the update appearing here.

How much is good timing worth?

In volatile weeks the gap between the cycle peak and trough can hit 30c/L, and combining timing with a cheaper suburb can stretch the practical gap to 60c/L. On a 60-litre tank, that is up to $36 saved on a single fill.

What is the difference between U91, E10, P95 and P98?

U91 is standard unleaded. E10 is a 10% ethanol blend, usually a few cents cheaper but slightly less fuel-efficient. P95 and P98 are premium grades with higher octane for performance and European vehicles. Always use the grade specified in your owner's manual.

About the data

How FuelRadar Australia forecasts and tracks prices

Every price is verified, official data — and every forecast is built on it, never crowdsourced.

Every price comes from official government price portals and retailer disclosures — never crowdsourced.
Prices refresh every 15–30 minutes; stations that haven't updated in 48 hours are dropped so the forecast and the averages stay accurate.
The price-cycle forecast learns from this same station-level data, so the call for your fuel matches the numbers shown across the site.

About FuelRadar

Australia's fuel forecast

What is FuelRadar?

FuelRadar forecasts the price cycle for your fuel and your local servos, then turns it into a clear call — fill up, worth waiting, or hold. It reads live petrol, diesel, LPG and premium prices from thousands of stations across Australia — 8,050+ servos, predicts the next jump or drop, and shows what good timing is worth on a tank. Knowing when to fill up, not just where, is the whole point.

The price cycle and the next jump

In major cities, petrol prices follow a weekly price cycle — prices spike sharply, then drift down for several days. FuelRadar learns each city's cycle and forecasts where it sits now, so you fill up near the bottom instead of guessing.

Fair price watch — wholesale vs what you pay

Every litre at the bowser starts with a wholesale terminal gate price set by the major refiners and importers, plus excise and GST. The gap between that wholesale figure and the price you actually pay is the retail margin — and the Fair Price Watch above shows whether retailers are passing the wholesale move through or padding their cut. When margins blow out beyond ~25c/L it is almost always worth driving a bit further, switching brand, or waiting out the cycle.
