Lubrication oil for gas/oil engines
Shengdong Group cooperates with China Great Wall Lubricant Company to produce special lubricating oil for Shengdong gas engine. Targeted product development according to the characteristics of different gases can provide more comprehensive care for gas-fired internal combustion engines and prolong the service life of the internal combustion engine. The special lubricating oil for standard gas engine is suitable for: natural gas, gas and other gas engines with low sulfur content; high sulfur
The special lubricating oil for type gas-fired internal combustion engine is suitable for gas engines with high sulfur content such as biogas, straw gas, coking gas, and industrial exhaust gas.
The special lubricating oil for gas internal combustion engine adopts foreign high-quality base oil and additives. During the research and development process, several targeted product improvements and upgrades have been carried out, and the product quality and performance have been further improved, which can replace similar foreign products (Mobil, Shell, Total, etc.).
