The plan to make a switch from the popular RON A92 petrol to biofuel E5 by January 1, 2018 may fail as ethanol plants have become bogged down in difficulties. Deadlines for replacing A92 petrol with E5 biofuel have been set up, but all of them have been missed. Most recently, state management agencies decided that all filling stations in Hanoi, Hai Phong, Quang Nam, Quang Ngai, Da Nang, HCMC, Can Tho and Ba Ria-Vung Tau must begin selling E5 petrol on June 1, 2016. However, the plan has failed. In late 2016, another plan was set up under which E5 petrol would be replaced RON 92 by June 2017. However, in the latest move, the Ministry of Industry and Trade has proposed to delay the E5 use to January 1, 2018.
