Effective July 1, RON95 will be priced at RM2.15 a litre and RON97 at RM2.55. Diesel remains unchanged at RM2.05.

Malay Mail Online understands that rumours of the imminent fuel price hike had been circulating among petrol station operators earlier today, which was then confirmed later in the evening.
