E10 gasoline is suitable for over 90% of vehicles.

The Ministry of Industry and Trade stated that E10 bioethanol is compatible with over 90% of vehicles currently in circulation, requires no engine modifications, and has the potential to significantly reduce polluting emissions.

E10 bioethanol is one of the solutions aimed at reducing dependence on fossil fuels.

The Ministry of Industry and Trade is seeking feedback on a draft government resolution aimed at removing obstacles and accelerating the roadmap for using E10 gasoline.

According to the drafting agency, this type of fuel is compatible with over 90% of vehicles currently in circulation, requires no engine modifications, and has the potential to significantly reduce polluting emissions.

According to the draft, E5 gasoline once accounted for about 40% of the market share but has now decreased to 15-20% due to the small price difference with conventional gasoline and consumer apprehension. The Ministry of Industry and Trade believes that to promote the consumption of biofuels, strong policies are needed, creating a clear price gap and strengthening communication.

Technically, E100 ethanol has an oxygen content of approximately 34.7% and a high octane rating of around 108 RON, resulting in more efficient combustion. Studies have also shown that E10 gasoline can reduce CO emissions by 20-30% and hydrocarbon emissions by 10-20% compared to conventional gasoline.

According to the Ministry of Industry and Trade, the demand for E100 ethanol for blending E5 and E10 gasoline is currently around 92,000 - 100,000 m3 per month, while domestic production is only about 25,000 m3/month.

If factories increase capacity and some projects are restarted, total supply could rise to around 44,000 m3/month, but this would still not be enough to meet demand.

Currently, Vietnam has 6 E100 production plants with a total designed capacity of approximately 500,000 - 600,000 m3/year, but the actual capacity only reaches 30 - 40%. Therefore, for at least the next year, Vietnam is expected to still have to import about 75,000 m3 of E100 per month to serve the blending of bioethanol.

Regarding infrastructure, by the end of March, 12 out of 26 major fuel distributors had invested in biofuel blending stations. In addition, 9 other businesses are awaiting licenses with a total capacity of over 260,000 m3/month.

If approved, the total blending capacity of E10 gasoline across the market will exceed 1.15 million m3/month.

The draft also states that the conversion from RON 95 mineral gasoline to E10 RON 95 gasoline does not require investment in new tanks, but businesses must upgrade their existing systems to suit the characteristics of the biofuel.

During the transition, businesses can choose to completely drain and flush the entire system before introducing E10 to ensure quality according to standards, or directly add E10 to the remaining tank containing approximately 20% mineral gasoline to save time and costs.

However, according to the Ministry of Industry and Trade, the second option may result in ethanol content not meeting standards for the first 15 days.

The agency stated that Vietnam now has a certain foundation for deploying E10 gasoline, such as a nationwide distribution system for E5 gasoline, several distributors have invested in blending systems, and many localities have been testing E10 sales since the beginning of August 2025.

However, for synchronized implementation, further obstacles related to infrastructure, ethanol supply, pricing mechanisms, and support policies still need to be addressed.
