What is the engine oil for China VI standard?
2 Answers
China VI standard engine oil is 5w30 semi-synthetic engine oil. Semi-synthetic engine oil: Semi-synthetic oil is one type of automotive engine oil. It is formulated using semi-synthetic base oil, specifically: internationally classified Group III base oil. This lubricant is a product derived from mineral oil through hydro-cracking purification technology, consisting of a 4:6 ratio blend of mineral oil and full synthetic oil. The purity of semi-synthetic oil is very close to that of full synthetic oil, though its cost is slightly higher than mineral oil; it serves as an ideal transitional product between mineral oil and synthetic oil. Full synthetic engine oil: Full synthetic engine oil represents the premium grade among engine oils. It is produced from ethylene or propylene dispersed from natural gas or crude oil gas, which then undergoes polymerization, catalysis, and other complex chemical reactions to form high-molecular lubricating fluids.
I've been driving a China VI vehicle for almost three years and found that choosing the wrong engine oil can cause significant issues. The China VI standard has strict emission requirements, and vehicles are equipped with GPF (Gasoline Particulate Filters). Conventional oils with high ash content can clog this component over time, costing at least several thousand yuan to repair. It's essential to use low-ash, low-sulfur low-SAPS oils, such as API SP-grade full synthetic oils, with common viscosities like 5W-30 or 0W-20. Last time, I used Mobil 1 at an authorized service center and noticed much quicker engine response and reduced noise. Never compromise by using older specification oils—the certification label is crucial for protecting the emission system and extending the vehicle's lifespan. Regular maintenance, including checking the oil filter and oil level, is vital. China VI cars may be a bit more delicate, but they offer eco-friendly and hassle-free driving. Hope my experience helps you.
