1.It is not necessary to use full synthetic oil for turbocharged engines with inferior oil, but it is strongly recommended to use full synthetic oil. Full synthetic oil can obtain relatively high shear resistance with relatively low viscosity. As we all know, oil viscosity is low and resistance is small. , the fluidity is fast, and the high temperature of the turbocharger requires high-efficiency heat dissipation. The low viscosity of the fully synthetic oil can improve the heat dissipation efficiency of the oil, which is of great significance to the turbocharger.

Mechanical loss, because the displacement of the turbocharged engine is smaller when the power is the same, so the size of its parts is also smaller, which can reduce a lot of friction resistance and motion loss. But when the throttle is light, there is only one crack in the throttle, and the engine can only inhale through this gap, just as we drink drinks with a very thin straw, which is very hard to absorb, so the naturally aspirated engine consumes more power on suction at this time.
