You know the drill, motorists. Fill up NOW or forever hold your peace.

Drivers in Perth and Mandurah have been warned to fill up today, because after prices skyrocket tomorrow by up to 46C in some locations, they are not likely to drop again for at least two weeks.

From 6am on Wednesday, the average price of regular unleaded petrol will increase by 33 cents per litre to 177.2C.

Coles Express hiking by up to 46C up to 189.9C, Caltex/Ampol and BP up to 187.9C, Vibe up to 187.7C, Caltex Woolworths up to 185.9C, Puma up to 185.7C, 7-Eleven up to 179.9C and United up to 176.9C.

Despite the average hike tomorrow, there are still 33 individual sites offering prices below 146C, so consumers should check the FuelWatch website to find the lowest price near them.

Buying fuel from the cheapest site rather than the most expensive, a difference of 52C, means motorists can potentially save $31 on a 60 litre tank.

Tuesday’s cheapest ULP is available for:

  • 139.7C at Puma Midvale in the East
  • 138.9C at 7-Eleven Cockburn Central in the South
  • 139.7C at Caltex Woolworths Greenwood, Puma Madeley and Puma Mount Lawley in the North.

Wednesday’s cheapest ULP will be available for:

  • 141.9C at Shell High Wycombe in the East
  • 137.7C at Costco Perth Airport (membership required) and 140.5 cpl at Caltex Woolworths South Lake and Caltex Woolworths Southern River in the South
  • 139.9C at Liberty Landsdale in the North.
