Fuel Wallet GaugeDomestic Trade and Consumer Affairs Minister Datuk Shahrir Abdul Samad says the ex-refinery prices of petrol and diesel in Malaysia have not dropped in tandem with crude oil prices so there is unlikely for prices at the pump to come down, or go up either. He added that ex-refinery prices are not openly available. Apparently ex-refinery prices used to move together with crude oil prices but now it is no longer the case, but he did not elaborate why it was no longer the case.
