After one month of nationwide sales, E10 biofuel has shown encouraging early results, with strong public support for the country's clean energy transition and growing consumer confidence in the quality of the new fuel.

The nationwide rollout of E10 biofuel is creating a significant market for domestically produced ethanol, boosting demand for cassava and agricultural by-products.

According to research, under heavy urban traffic conditions, E10 biofuel can be 2.3-7.8 percent more economical than RON 95 gasoline. However, when vehicles run at speeds of 60-70 km/h, E10 may consume more fuel.

Concerns over E10 gasoline quality have prompted lawmakers to recommend stricter monitoring and greater public communication.

The Ministry of Industry and Trade has moved to reassure motorists about E10 gasoline as nationwide sales surge past 141 million liters.

Many drivers worry that E10 fuel is highly volatile and has a lower heating value than traditional mineral gasoline, causing vehicles to consume more fuel during scorching days.

According to the Ministry of Industry and Trade’s roadmap, starting June 1, E10 biofuel will be rolled out nationwide, completely replacing traditional RON95 mineral gasoline.

Vietnam's Ministry of Industry and Trade says supplies of E5 and E10 biofuels are sufficient nationwide and that no significant technical problems linked to biofuel use have been recorded so far.

Deputy PM Pham Gia Tuc has called for greater transparency regarding the quality, technical standards & vehicle compatibility of E10 biofuel, stressing that consumer interests must remain at the center of Vietnam’s nationwide transition to the fuel.

Vietnam's Ministry of Industry and Trade answers key questions about E10 gasoline, including engine safety, fuel economy and vehicle compatibility.

Vietnam's nationwide transition to E10 gasoline follows years of practical testing and aligns with a global trend toward cleaner transport fuels.

Dao Duy Anh, deputy director of the Department of Innovation, Green Transition, and Industrial Promotion, says that vehicle operation with E10 gasoline has shown no significant difference compared to the use of traditional RON95 mineral gasoline.

Vietnam’s Ministry of Industry and Trade has sought to ease public concerns over the planned nationwide rollout of E10 gasoline, stressing that the transition is being implemented gradually rather than imposed on consumers.

Alongside debates over engine compatibility with E10 biofuel gasoline, social media has seen many videos teaching people how to manually separate alcohol from E10 fuel, attracting hundreds of thousands of views.

The Petrovietnam Refining and Petrochemical Corporation (BSR) will produce and distribute between 80,000 and 100,000 cubic metres of E10RON95 biofuel petrol per month to meet growing market demand for E10 fuel during May 2026 and months to come.

Major automakers including Honda, Toyota, Hyundai, Ford and Mercedes-Benz have confirmed that most modern vehicles currently operating in Vietnam are compatible with E10 biofuel, easing concerns ahead of the fuel’s nationwide rollout from June 1.

The Agency for Domestic Market Surveillance and Development has instructed provincial and municipal departments of industry and trade to strengthen supervision and inspections related to the nationwide rollout of E10 biofuel petrol.

Many fuel stations in Ho Chi Minh City have started replacing traditional gasoline with E10, marking a major step in Vietnam’s green energy roadmap.

Ahead of schedule, several major fuel distributors have begun rolling out E10 biofuel across their retail networks and are preparing to supply the market beyond their own systems.
