According to the Domestic Trade, Co-operatives and Consumerism Ministry, RON95 will go up by seven sen to RM2.31 per litre while RON97 will go up by six sen to RM2.60 per litre.

The last time petrol prices hit a record high under the new system was on April 20 when RON95 was RM2.27 per litre, while RON97 was RM2.54 per litre.

Meanwhile, the price of diesel will go up by three sen to RM2.20 per litre.

It is the second highest price under the new system.

The weekly fuel price system was implemented on March 30.

It is determined by global oil prices based on the Mean of Platts Singapore (MOPS) and the ringgit's strength against the US dollar.
