Does the new Buick GL8 have a particulate filter?
2 Answers
The new Buick GL8 has a total of 16 models, all equipped with particulate filters. The entire lineup uses a 2.0T turbocharged engine that meets the China VI emission standards. Except for a very few models, almost all China VI-compliant vehicles are equipped with particulate filters. After the China VI standards were released, automakers found it almost impossible to meet the standards without changing the design direction, R&D investment, or performance. Therefore, most China VI-compliant models are equipped with particulate filters. To check if a vehicle has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates the vehicle is equipped with a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe to see if there is an additional cylindrical section. If present, that is the particulate filter.
As a seasoned car enthusiast who frequently researches various vehicles, I can confirm that the new Buick GL8 is indeed equipped with a particulate filter. This device is primarily used to filter fine particles from exhaust emissions, reducing air pollution, as the current China VI emission standards are extremely stringent. The GPF system automatically cleans itself during operation, but if you typically drive short distances, such as just a few kilometers for commuting, it may trigger a clogging warning light. In such cases, you need to drive at high speeds to allow it to regenerate. From my experience, this technology is quite easy to maintain—just change the engine oil and air filter during regular maintenance. It’s environmentally friendly and ensures driving safety, making it worthy of being adopted in more vehicle models.
