The 31-sen decrease will come into effect from midnight tonight and will remain until Dec 31, the ministry announced on its Facebook page earlier tonight.

Meanwhile, prices for RON95 petrol, at RM2.20 per litre, and diesel (Euro 2M diesel) at RM2.18 per litre and Euro 5 diesel at RM2.28 per litre, remain unchanged.

In October, RON97 petrol went up 14 sen to RM2.79 while this month it was retailed at RM2.79 per litre.

Finance Minister Lim Guan Eng previously said the price of RON97 is based on market movements while RON95 and diesel prices will remain unchanged until the end of 2018.

This is in line with Prime Minister Dr Mahathir Mohamad’s announcement on May 30 that the government will retain the prices of RON95 and diesel whereas RON97 will be subject to a float system.
