Master Wu in Xinzhou bought a Haval H6 in September last year, and the engine failure light was lit three times less than half a year after the new car was on the road. After the failure occurred, Master Wu drove the car to the 4S shop for maintenance, and after the maintenance master eliminated the fault light every time, he let Master Wu drive away.

Master Wu was very puzzled, what was the reason for the three failure lights of the vehicle, he never knew, until the eighth day of the first month of the first month, the car was completely unable to hit. However, for this situation, haval 4S shop said that it was because Master Wu added bad oil to the car, resulting in water in the fuel tank and the engine failure.
Master Wu was very helpless, he said that he went to the regular gas station to refuel. In this regard, the Haval 4S store took out the testing pictures at that time, and pointed out that the oil pipe that was pulled out at that time actually spewed water...
Is the failure of the vehicle related to the oil added by Master Wu?
