Unleaded gasoline must be blended into E10 gasoline for use in gasoline engines nationwide starting June 1, 2026. Experts highlight the most important consideration as tens of millions of motorbikes and cars switch to E10.

Vietnam will officially mandate the use of E10 fuel across the country starting June 1, 2026, replacing all conventional unleaded gasoline.

The use of biofuel, which helps ensure energy security and protect the environment, will allow farmers to avoid selling millions of tons of dry cassava to China at unstable prices.

The number of customers choosing E10 gasoline remains limited, with most of them  being car owners.

A recent study by Hanoi University of Science and Technology (HUST) shows that E10 gasoline significantly reduces hydrocarbon and carbon monoxide emissions compared to E5 and A95 gasoline.

Despite support from fleet operators, Ho Chi Minh City drivers remain cautious about using E10 fuel, citing engine concerns and social media rumors.

Many social media forums are sharing information that as of January 1, 2026 the market will only produce and circulate E10 gasoline.

Customers are less concerned about whether fuel is eco-friendly and more focused on vehicle durability after refueling. This is why many do not choose E10 bio-gasoline.
