Short-term Diesel shortage remains in WA

At least 52 service stations in Western Australia remain without diesel after a "short-term interruption" to supplies.

FuelWatch said as at 2pm (WST) on Sunday, there were 42 service stations without diesel in metropolitan Perth and 10 in the regions.

But the FuelWatch tally does not include BP outlets and small independents, and there could be Caltex and Coles sites without diesel that FuelWatch has not counted.

The number of known affected fuel retailers has decreased since Saturday when FuelWatch was aware of 101 sites having run out of diesel across the state.

FuelWatch said motorists should phone ahead to check whether a service station had diesel supplies before driving to make a purchase.

BP said on Thursday that the shortage was due to a shipment of imported diesel having slight discolouration during checks to ensure it met Australian standards.

Following further technical inquiries to ensure the diesel was fit to use, BP said supplies could be slower than usual to arrive.
