Point in Fuel Cycle

Trough” point in
the cycle, where
prices are
coming down.
26 Feb 2020
ANALYSIS This snapshot shows the unreliability of current “real-time fuel pricing” apps available from the private sector, given only 11 retailers out of the 22 (or 50%) had prices at the pump which matched those advertised on the private app ‘MotorMouth’. The one retailer who did not appear on the app is the smallest independent operator in the sample area.
Of the other 10, all prices were lower at the pump than advertised on the app, ranging from 2c/l to 7c/l cheaper. This could be due to the point in the fuel cycle 4 days after the observed ‘peak’, where prices are on their way down. The discrepancies can be attributed to lag, where reported prices (either by retailers or passing motorists) take time to reflect the actual situation in ‘real-time’.
This can be seen in the following example at the Coles Express on Montague Road in Modbury North, where the price was taken later that day at 1:08pm. The price at the pump had changed to 141.9c/l, yet the app still displayed the price that was on offer at 11:30am.

ANALYSIS (continued) The Modbury North site was one of the 11 stations in the morning that had the correct price listed on the app, yet less than three hours later, had a price difference of 3c/l. It would be fair to assume that similar lag on the other side of the cycle (the “Trough-to-Peak”), when prices are on their way up, would result in prices being higher at the pump than shown on private apps. With this level of uncertainty, it would be difficult for consumers to make use of the information provided by real-time fuel pricing apps as they currently operate, as the price can be different (lower or higher, depending on the point in the cycle) merely hours after they have checked. The inaccuracies in the current system arguably deny consumers a fully informed choice, so they are unable to access petrol at the best possible price.
