Is there a cheapest day to buy petrol in Sydney?
There was no cheap day of the week for unleaded petrol in Sydney from 1 April 2026 to 30 September 2026: every weekday averaged within 0.2 c/L of its weekly mean across up to 846 stations.
Method: for each day from 1 April 2026 to 30 September 2026, the U91 price in force at noon at each of up to 846 Greater Sydney stations (NSW FuelCheck), averaged; each day's average is compared with the average of the 7 days centred on it, then averaged by weekday.

Times are local to Sydney. March prices seed the opening day; subsequent changes carry forward across months. Prices must be strictly between 120 and 350 c/L. The first and last three days are excluded from weekday comparisons because they lack a complete centred window. Station counts vary by day.
Sydney's average unleaded price rose 84 c/L in 12 weeks, from 153.4 c/L on 30 June 2026 to 237.5 c/L on 24 September 2026.
Method: use the lowest daily station mean in the published series and the highest daily mean after that low; round elapsed days to weeks. Daily means use the noon station prices described above.
