Pump prices of RON95 petrol will go up by RM0.10 per litre beginning midnight amidst falling global crude oil prices since June 10.
Prices of RON97 petrol will go up by RM0.20 per litre while diesel prices remain unchanged.
This means that RON95 petrol will cost RM2.15 per litre while RON97 petrol will cost RM2.55 per litre.
The new prices were confirmed with several petrol station operators.
Putrajaya has announced that it would no longer warn consumers prior of fuel price increase and consumers would have to find out for themselves at the petrol station at the beginning of every month.
The Petrol Dealers Association of Malaysia (PDAM) told Malaysiakini that they agreed with this move, because it would help ensure "smooth operations" of petrol stations.
What PDAM likely meant was that the move would discourage long queues at petrol stations every time prices were increased.
Pump prices have been put on a managed float since after fuel subsidies were removed in December last year.
The price of RON95 petrol reached a low of RM1.70 per litre on February 1 when crude oil prices were hovering around USD60 per barrel.
Crude oil prices recently peaked at about USD69 per barrel in early May, but has been steadily dropping since.
