What grade is SPGF6 engine oil?
2 Answers
SPGF6 is an SP-grade engine oil. Here are detailed introductions to the advantages of SPGF6: 1. Performance: Excellent driving performance and superior acceleration. 2. Compatibility: Outstanding compatibility with gasoline engine particulate filters. 3. Protection: Provides excellent protection against low-speed pre-ignition in engines. Effectively protects engines with turbocharged direct injection technology. Here are additional details: According to the viscosity grade classification method, lubricants are divided into three types: high-temperature type for summer, low-temperature type for winter, and all-season type suitable for both winter and summer.
I previously specialized in studying motor oil standards, and SP GF-6 is currently the highest-grade oil certification available on the market. It is significantly stricter than the previous SN grade, specifically designed for China VI emission-compliant engines, especially vehicles equipped with particulate filters. This type of oil effectively prevents low-speed pre-ignition issues (abnormal knocking that occurs in some turbocharged engines) and reduces sludge formation. Based on lab data, it provides excellent protection for turbochargers and can also improve fuel economy, making it most suitable for newer Japanese and American cars. Nowadays, SP-grade oil is basically the standard recommendation for initial maintenance of new cars at 4S shops.
