The use of E10 gasoline not only helps reduce emissions but also reduces dependence on imported fossil fuels, promotes the consumption of domestic biofuels, creates outlets for agricultural production, and enhances national energy self-sufficiency.

Ensuring vehicle engine safety

According to the government's roadmap, E10 gasoline will officially be sold nationwide from June 1st. However, a matter of particular public concern is the level of safety of this type of gasoline for vehicle engines. Regarding this issue, Deputy Director of the Department of Innovation, Green Transformation and Industrial Promotion ( Ministry of Industry and Trade ) Dao Duy Anh affirmed that during the development of the biofuel roadmap, the Ministry conducted surveys and assessments on the potential impact of E5 and E10 biofuels on engine performance and lifespan.

Assessments by scientists at Hanoi University of Science and Technology and the University of Transport and Communications show that E5 and E10 gasoline do not negatively impact the performance or lifespan of engine components in gasoline engines. Vietnam has been using E5 gasoline nationwide since 2018, while E10 gasoline has been piloted since August 2025.

To date, neither distribution businesses nor the Ministry of Industry and Trade have received any feedback regarding whether E5 or E10 gasoline negatively affects the performance or lifespan of vehicle engines.

Mr. Dao Duy Anh further informed that international experience also shows that biofuels have been used for a long time, such as the US and Brazil using E10 gasoline since the 1980s. Countries in the Southeast Asian region such as Thailand and the Philippines have used E15 gasoline, and are even upgrading to E20 without recording any negative impacts on vehicle engines.

E10 gasoline has been researched, tested, and evaluated as suitable for most vehicles currently in circulation.

Deputy Minister of Industry and Trade Nguyen Sinh Nhat Tan affirmed that E10 gasoline has been researched, tested, and evaluated as suitable for most vehicles currently in circulation. The roadmap for transitioning from mineral gasoline to bio-gasoline is being developed step-by-step, with thorough impact assessments, and will not be implemented abruptly. During the implementation process, the Ministry will continue to coordinate with other ministries, sectors, and businesses to ensure a stable supply, fuel quality, and transparent information to reassure consumers.

According to a representative of the Vietnam Automobile Manufacturers Association, the materials used in the manufacturing of vehicles currently on the market have been researched and selected to be alcohol-resistant, so there will be no corrosion or aging of rubber seals if customers use the correct, standard-compliant E10 gasoline.

However, the association representative also advised customers not to leave their vehicles unused for too long, especially when the fuel tank is low. Ethanol is hygroscopic and can cause condensation in the fuel tank. Users should adhere to the manufacturer's recommended fuel filter replacement schedule to ensure the fuel system remains clean.

Ready to meet demand

According to Do Van Tuan, Chairman of the Vietnam Biofuel Association, most motorcycle models manufactured from 2000 to the present are compatible with E10 gasoline. Circular No. 50/2025/TT-BCT of the Ministry of Industry and Trade stipulates a mandatory roadmap for applying the blending ratio of biofuels with traditional fuels in Vietnam.

The Vietnam Motorcycle Manufacturers Association also affirmed that motorcycles using E10 gasoline are completely safe. While some parts of older models, such as rubber gaskets or fuel lines, may age faster, this only affects the rubber material after prolonged use and does not directly impact the engine.

Replacing these parts is simple and inexpensive. Concerns that E10 gasoline may damage engines, corrode engine parts, or reduce vehicle lifespan are completely unfounded and unproven in practice.

Globally, a key commonality among countries that have successfully developed biofuels is the availability and stability of their raw material sources. This is a crucial factor determining the ability to produce on a large scale. Vietnam, however, remains heavily reliant on imported fuels.

In the future, to accelerate the use of biofuels, Vietnam needs to develop a comprehensive and stable policy, including price support mechanisms and incentives for businesses involved in production and consumption. Furthermore, it is necessary to develop sustainable raw material areas linked to domestic agriculture to ensure a proactive supply of ethanol, as well as invest in distribution infrastructure, helping people understand and trust in its use.

Deputy General Director of Vietnam National Petroleum Group (Petrolimex), Nguyen Quang Dung, affirmed: Across the entire system, gasoline sales volume currently reaches approximately 400,000-500,000 m³/month. Petrolimex has prepared a comprehensive supply plan and contracts to meet consumption needs and match the company's blending capacity. In fact, since 2018, Petrolimex's E5 and E10 gasoline have been operated under strict control procedures and no incidents related to the quality of biofuels have been recorded.

Similarly, Vietnam Refining and Petrochemical Corporation (BSR), a member unit of the Vietnam National Energy and Industry Group (Petrovietnam), has just exported its first 12,000 m3 of E10 gasoline by sea to a business enterprise.

In May and the following months, BSR will produce and sell approximately 80,000-100,000 m³ of E10 gasoline each month. Implementing two sales methods helps the company increase flexibility in supply, expand distribution scope, and improve its ability to meet nationwide consumption needs.
