What kind of engine oil is best for turbocharged engines?

[ONatalie]

Turbocharged engines use fully synthetic engine oil with a viscosity of 40, while some turbocharged engines require fully synthetic engine oil with a viscosity of 60. Precautions for using engine oil: The viscosity of the engine oil should not be too high or too low. If the viscosity is too low, the engine oil cannot form a stable oil film during engine operation, which will affect engine lubrication and accelerate engine wear. If the viscosity is too high, the resistance during engine operation will increase, affecting power output and fuel economy. Turbocharged engines operate under high pressure and temperature in the cylinders, so such engines cannot use engine oil with too low viscosity, as it cannot provide sufficient lubrication. Functions of engine oil: Engine oil is known as the lifeblood of the engine. Inside the engine, it not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. Without engine oil, the engine cannot function properly. During normal engine operation, engine oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between them.
