The color of E10 gasoline depends on its mineral gasoline source, production process, and additives used; it does not reflect fuel quality or the ethanol blending ratio.

A representative from the Ministry of Industry and Trade stated that information regarding vehicles experiencing issues after refueling with E10 gasoline requires specific cause verification, rather than prematurely attributing them to fuel quality.

Older vehicles incompatible with E10 should prioritize using E5 gasoline, replace E10-compatible components, and regularly maintain the fuel system.

Most motorcycles and cars in Vietnam are compatible with E10 gasoline; only a few older vehicles do not support this type of fuel.

Deputy Minister of Industry and Trade Nguyen Sinh Nhat Tan announced that the ministry will carry out unannounced inspections of businesses to ensure E10 gasoline quality from production and blending to market distribution.

The Deputy Prime Minister has urged ensuring fuel supply, quality, and consumer rights as the nation shifts to E10 gasoline.

Some malfunctions, such as hesitation, engine stalling, or difficulty starting, may appear in older cars using E10, but are usually fixable with maintenance.

Ahead of E10 gasoline's nationwide implementation from 1/6, the Ministry of Industry and Trade released a Q&A document addressing numerous public concerns about using E10 biofuel gasoline.

Both are bioethanol fuels containing 9-10% ethanol by volume and 90-91% mineral gasoline, differing in their quality standard classification.

Despite ethanol's moisture-absorbing properties, Petrolimex reports no phase separation observed in E10 samples stored for three months.

Most electronic fuel injection cars can self-adjust fuel delivery when transitioning to E10, so general users typically do not need to remap the engine control unit.

The Deputy Minister of Industry and Trade stated that maintaining multiple fuel types for an extended period increases logistics and distribution costs, hindering the effectiveness of the green energy transition.

E10 gasoline is a finished product blended from RON95 III gasoline and ethanol alcohol, adhering to national technical standards for biofuels.

While E10 gasoline may result in slightly higher fuel consumption, numerous studies indicate its impact on engine power and durability is not substantial.
