Is SP Grade Engine Oil Suitable for China 6?

[MacKathryn]

Suitable, although SP grade engine oil is not specifically designed for China 6 vehicles, it is quite beneficial for them. Here are the details: 1. China 6: After the official implementation of the China 6b emission standard, automakers are compelled to impose higher requirements on engine emissions. The most effective method to make engines comply with the China 6b standard is to add a particulate filter at the end of the vehicle's three-way catalytic converter. However, prolonged use of conventional engine oil, which contains combustion byproducts such as sulfate ash, phosphorus, and sulfur, may increase the likelihood of the particulate filter getting clogged. 2. SP Grade Engine Oil: SP grade engine oil requires the use of low SAPS (low sulfur, low phosphorus, low ash) additives, which can help prevent excessive accumulation of combustion byproducts on the particulate filter, thereby reducing the risk of clogging.
