What are the requirements of a particulate filter for engine oil?

[VanNicole]

Particulate filter requirements for engine oil: National VI engines equipped with particulate filters require the use of low-ash engine oil. High-ash oil can easily clog the particulate filter. The methods for dealing with clogged particulate filters differ between diesel and gasoline vehicles, as follows: For diesel vehicles, simply press the regeneration button on the car. The engine will then increase its RPM while stationary, and generally, within about ten minutes, the particulate filter will be cleaned, resolving the clogging issue. For gasoline vehicles, the owner should first shift the car into S gear and then drive at high speed for a period. During high-speed driving, the exhaust pipe temperature will rise, burning off the clogged particles inside the particulate filter, thereby solving the clogging issue. If the particulate filter is severely clogged and the above methods do not resolve the issue, the particulate filter can be taken to an auto repair shop or 4S store for professional cleaning with specialized equipment.
