Generally speaking, the high temperature resistance of all synthetic engine oil can be achieved. My car is also a turbocharged engine. Before, I used the original all-synthetic engine oil, but the high temperature resistance was not good, and the performance of engine oil declined rapidly. It will be troublesome to change it after 8000 kilometers. At present, the GT Maroon 5 used in the car is very good, and the grade IV PAO base oil has good quality and high temperature resistance. You can run about 65,438+05,000 kilometers every time you change the oil, which is very easy to use!
