CẦN THƠ — Cần Thơ City police on Wednesday announced they were testing petrol samples of three local fuel providers, following a police bust seizing petroleum of questionable quality.
The police on the previous day caught red-handed a staff member of Vạn Nguyên 2 Petrol Company pumping some 6,000 litres of detergent solvent from a tanker into another one, which contained 3,000 litres of the solvent mixed with 3,000 litres of petrol.
The solvent was identified as Solmix industrial detergent.
The company manager, Nguyễn Văn Trung, failed to present official documents proving the origin of the liquid detergent and the petrol.
Busting another Vạn Nguyên warehouse, managed by Trung’s father Nguyễn Văn Nguyện, the police found another thousands of litres of petrol without proper documents and thousands of litres more at a different petrol provider, Khải Hà.
Detergent is often added to petrol before it is brought into the market in order to reduce the buildup of deposits in engines. However, the use of detergent should be permitted by the authorities and the final petrol product must meet fuel standards.
Solmix detergent was found in a number of cases previously, where the petrol mixed with the detergent was sub-standard. — VNS
