What type of engine oil should be used for turbocharged models?
2 Answers
Turbocharged models require 5w40 or 0w40 type engine oil. The capacity for oil change and situations requiring oil change are as follows: Oil change capacity: Different models have different sizes of oil pans, so the amount of oil required for replacement varies. Generally, sedans require about 4L, mid-size and large sedans about 4.5L, and compact cars about 3.5L. Please refer to the maintenance manual for specific details. Situations requiring oil change: Check the viscosity of the engine oil; if there is no viscosity, the oil needs to be changed; the color of the oil turns black; excessive black particles, metal shavings, or carbon deposits in the oil; the smell of the oil is abnormal. If the oil is not changed, it will turn black and deteriorate, reducing lubrication effectiveness and potentially causing engine damage.
The turbocharged car I previously drove used 5W-40 full synthetic oil, which worked exceptionally well. Since turbo engines operate at much higher temperatures than regular cars, conventional mineral or semi-synthetic oils can't withstand the heat, and insufficient lubrication can lead to bearing wear. I once experienced engine noise during acceleration after using low-viscosity oil, and upon inspection, found the oil film had torn. Later, switching to an API SP-certified high-temperature protection oil resolved the issue. I recommend fellow car enthusiasts to refer to their vehicle manuals when choosing oil—typically 5W-30 or 5W-40—and not to skimp on quality. Maintain oil change intervals between 5,000 to 7,500 kilometers. This not only protects the turbo and extends its lifespan but also saves on repair costs. I service my engine every six months, and it runs smoothly without any issues.
