Lai Chau police have arrested a Petrolimex store manager, after more than 12,500 litres of diesel mixed with petrol was reportedly sold over six weeks, according to Dau Tu Kien Thuc reporting.
Investigators said staff at the petrol station accidentally pumped more than 500 litres of regular petrol into a diesel tank on March 26.
It’s then alleged that the store manager in question tried to cover up the error by adding additional diesel; the mix was then sold to consumers through May 8.
This is noteworthy in that it feeds into a broader narrative around pricing pressures in the fuel market, where operators have repeatedly warned that government price controls and rising global fuel costs are squeezing margins — regulated retail prices have even fallen below cost price several times in recent years, leaving fuel retailers selling petrol at a loss.
Under these circumstances, it would make sense that a fuel retailer might not want to write off the 500 litres of petrol or the diesel that was in the tank before the petrol was added.
Notably, on March 26, petrol prices in Vietnam were up about 21 percent compared to the end of February.
Moreover, it has knock-on costs — the petrol-diesel mix was only uncovered when a local resident filled two excavators, which subsequently malfunctioned. These machines will need to be repaired, not to mention all of the other vehicles that had filled up in the six weeks prior to it being found out.
That’s not to mention the reputational damage for the store and the brand, and the store manager, too.
That is to say, margin pressure generally doesn’t disappear but is often transferred elsewhere in the system, whether through reduced maintenance, weaker oversight, operational shortcuts, or risks to product quality.
The point being that whereas price caps might keep fuel affordable for consumers, they also create risks that come with their own costs: consumers might save at the pump, but will likely pay for it somewhere else.
