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.
Some malfunctions, such as hesitation, engine stalling, or difficulty starting, may appear in older cars using E10, but are usually fixable with maintenance.
The Ministry of Industry and Trade has instructed automobile and motorcycle manufacturers to review and announce E10 gasoline compatibility, and to prepare technical support plans for consumers.
Bui Ngoc Bao, Chairman of the Vietnam Petroleum Association, stated that E5 and E10 bio-gasoline do not harm engines if vehicles are properly maintained and meet technical requirements.
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.
While E10 gasoline may result in slightly higher fuel consumption, numerous studies indicate its impact on engine power and durability is not substantial.
