Frequently, oil traces may be made due to leakproofness of the joints. However, the problem with the oil conjecture of the Tighuan patrol car in Russia is attributed to the use of synthetic oil in the engine.
The manufacturer states that conjecture is apparent from the special additives intended to minimize the wear of the engine, reduce oxidation and prevent the formation of sediments. And specifically, because of the volatility of these additives. At high temperatures, they can evaporate and leak even through sealed connections. However, these oil marks, as the Volkswagen assure, are not a malfunction, do not increase the oil consumption in the car and do not affect the operation of the machine.
