Vietnam to mandate E10 bio‑fuel gasoline nationwide by June 2026

Vietnam began selling gasoline blended with 10% ethanol (E10) in late April 2024 and will require all fuel sold across the country to meet the E10 standard from 1 June 2026. The move follows similar policies in the United States and aims to cut dependence on imported crude, lower transport‑sector CO₂ emissions and boost domestic energy security.

The Ministry of Industry and Trade says E10 is only the first step; studies are under way for higher blends such as E15 and E20. Local ethanol, produced mainly from cassava, corn and sugarcane, could supply roughly 1 million tonnes a year for E10, rising to about 1.5 million tonnes if higher blends are adopted. Vietnam currently has six ethanol plants operating at about 35 % of capacity, with the potential to expand as demand grows.

Petrolimex reports that most newer cars can run on E10 without modification, but owners of older or poorly maintained vehicles should inspect fuel‑system components—especially filters, hoses and rubber parts—because ethanol can absorb moisture and clean deposits more aggressively. Users are also advised not to let vehicles sit with fuel in the tank for extended periods, as this can affect fuel quality. The transition is expected to bring environmental benefits, improve air quality and offer a higher octane rating that can enhance engine performance.
