Turbocharger life is only 5 years?
Turbo and engine life are the same, it can be said that in the entire vehicle life cycle, the turbo is one of the most reliable components, if not used improperly, it does not need to be replaced.
The turbocharged car needs to be warm for a while when it starts, and it needs to idle for a while before turning off after parking, otherwise it will damage the engine?
Hot car habits are more helpful in extending engine life, including naturally aspirated and supercharged engines, but it only takes a few seconds to complete. At room temperature of 20 degrees Celsius, it only takes 1 second for the oil to rush into the bearing, creating an oil film and avoiding dry friction. Even at minus 30 degrees in winter, the fuel supply time is within 5 seconds.
Idle speed is a habit left by the old generation of superchargers. Users are required not to turn off the engine immediately after driving at high speed for a long time, but to let the engine continue to run for a few minutes, in order to prevent the turbocharger from overheating and malfunctioning. But now the latest turbocharged models have a cooling circulation system inside the turbocharger. When the engine is turned off, the cooling of the turbo can still be continued until it returns to a safe value. The owner can turn off the engine normally, and there is no need to keep idling for a while. time.
