What kind of engine oil should be used for turbocharged engine maintenance?

[EvaLee]

For turbocharged models, it is recommended to use fully synthetic engine oil. The following is an introduction to fully synthetic engine oil: 1. Fully synthetic or semi-synthetic engine oil should have good anti-wear properties, high-temperature resistance, high oil film strength, and strong shear resistance. 2. There are four types of vehicles recommended to use fully synthetic engine oil: turbocharged models, large-displacement models, direct-injection engines, and vehicles often driven in extreme climates. 3. The higher the engine speed, the stronger the oil's shear resistance is required. Shear resistance is the guarantee of oil viscosity stability. Only in this way can the lubrication ability of the oil not decrease at high speeds. Fully synthetic engine oil is superior to ordinary mineral oil, especially in terms of shear resistance, where its advantages are particularly outstanding.
