The average cost of unleaded petrol is set to increase by around 14 cents per litre (cpl) to 135.5 cpl tomorrow, so FuelWatch is encouraging Perth drivers to fill up today to save money.

FuelWatch advises that on Tuesday 20 December 2016, most Coles Express sites are increasing their ULP price to 139.9 cpl (an increase of 17 cpl). Most Caltex Woolworths sites are increasing their ULP price to 138.9 cpl, most BP, Caltex and Puma sites to 136.9 cpl and most United sites to 136.7 cpl.

Perth’s weekly petrol price cycle results in prices, on average, being cheapest on Sunday and Monday and at their most expensive on Tuesday and Wednesday – that’s why FuelWatch recommends filling up today.

If you need to fill up tomorrow, use FuelWatch as there are still more than 35 sites selling below 126 cpl. The difference between the highest and lowest priced sites is 23 cpl, which means you can save up to $13 on a 60 litre tank of fuel.

Monday’s cheapest ULP is available for:

• 111.4 cpl at Puma Midvale in the East;
• 113.4 cpl at Puma Warnbro in the South; and
• 111.4 cpl at Puma Malaga in the North.

Tuesday’s cheapest ULP will be available for:

• 116.0 cpl at Chidlow Growers Mart Liquor Store in the East;
• 118.9 cpl at BP Port Kennedy in the South; and
• 118.9 cpl at Puma Neerabup in the North.
