The turbocharger utilizes high-grade synthetic oil.

Due to the increased combustion temperatures and working pressures within the engine during operation compared to naturally aspirated engines, turbocharged engines demand higher levels of lubrication and cooling. Standard mineral oils are insufficient to meet the demands under more stringent operating conditions, necessitating the use of synthetic oils with superior lubricating and cleaning capabilities. Synthetic oils outperform mineral oils in terms of lubrication, cleaning, and anti-friction properties, featuring faster oil film formation, higher film strength, and better stability. Therefore, it is essential for turbocharged vehicles to use synthetic oils, with full synthetic oils being recommended.

Turbocharged direct-injection engine requires the use of injector cleaner.

Now, an increasing number of supercharged engines are equipped with direct injection technology, and all supercharged engines have this technology. Direct injection involves injecting fuel directly into the cylinder, where it mixes with air. By controlling the amount and timing of fuel injection based on the intake air volume, a mixture with the theoretical air-fuel ratio can be achieved, leading to more complete combustion and thus reducing fuel consumption while enhancing the engine's power performance. However, due to their direct placement in the cylinder, the injectors of direct-injection engines are prone to the formation of varnish and carbon deposits. It is generally required to periodically clean the injectors by adding an injector cleaner to the gasoline. If the varnish and carbon are extremely severe, the injectors need to be removed for cleaning.

3. It's crucial to regularly inspect turbochargers.

Turbocharged engines, due to their numerous components, require regular attention to ensure there are no unusual noises or vibrations from the turbocharger. Check for leaks in the oil lines and connections. Inspect if there is any oil residue at the turbocharger's exhaust outlet and if there is oil inside the compressor's intake straight pipe. The phenomenon of oil consumption in turbocharged engines is not a widespread issue. However, as a precaution, it is recommended that owners regularly remove the engine oil dipstick to check the oil consumption status and ensure the oil level is within the normal range. If visible oil consumption is detected, promptly visit a repair shop for inspection.
