Weekly fuel price cycles have returned in Perth and Mandurah instead of fortnightly.
Today is the most expensive day for fuel with the average price of regular unleaded jumping 26 cents per litre (cpl) to 190.3 cpl.
Some Caltex/Puma sites have hiked their prices by up by 44 cpl to 203.9 cpl.
Motorists will likely only have to wait a week before petrol prices are again at the bottom of the price cycle.
Locals can find the cheapest fuel today at the membership based Costco Casuarina for 154.7 cpl or further south at Vibe Pinjarra and Liberty Pinjarra at 162.3 cpl.
Buying fuel from the cheapest site rather than the most expensive, a difference of 49 cpl, means motorists can potentially save $29 on a 60 litre tank.
