Motorists in Perth and Mandurah are advised to fill up now if they need to, with petrol prices set to rise tomorrow. After today motorists will likely have to wait a week before petrol prices are again at the bottom of the price cycle.

FuelWatch reports that, from 6am tomorrow (Wednesday 20 September 2023), the average price of Perth’s regular unleaded petrol (ULP) will increase by 30 cents per litre (cpl) to 223.5 cpl with Ampol hiking up to 235.9 cpl; EG Ampol and Caltex up to 233.9 cpl; Puma up to 233.7 cpl; BP up to 232.9 cpl; Coles Express and 7-Eleven up to 229.9 cpl; United up to 229.5 cpl; and Vibe up to 228.9 cpl.

Despite the average hike tomorrow, there are still 26 individual sites offering prices below 196 cpl, 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 49 cpl, means motorists can potentially save $29 on a 60 litre tank.

Tuesday’s cheapest ULP is available for:

  • 189.7 cpl at 7-Eleven Wattle Grove and Vibe Forrestfield in the East;
  • 186.7 cpl at Costco Perth Airport (Costco sites are membership based) and 186.9 cpl at EG Ampol South Lake in the South; and
  • 187.9 cpl at BP Dog Swamp (Yokine), BP Morley, EG Ampol Aveley, EG Ampol Banksia Grove, EG Ampol Greenwood, EG Ampol Joondalup Winton Road and Liberty Tapping in the North.

Wednesday’s cheapest ULP will be available for:

  • 191.9 cpl at Shell High Wycombe in the East;
  • 186.7 cpl at Costco Perth Airport, 187.7 cpl at Costco Casuarina and 188.3 cpl at Vibe Welshpool the South; and
  • 189.9 cpl at Liberty Landsdale in the North.
