Short Description:
Product Overview:
This product is formulated with synthetic oil, hydrotreated base oil, and high-quality multifunctional additives.
Performance Characteristics:
• Effectively disperses soot and deposits, controls engine sludge and piston ring deposits, ensuring engine cleanliness and reducing energy loss caused by friction and wear;
• Excellent acid neutralization performance, preventing rust and corrosive wear of engine components;
• Ultra-low evaporation loss, effectively improving the impact of oil evaporation on fuel economy, oil consumption, exhaust emissions, and engine wear under high-temperature conditions;
• Good rubber compatibility, effectively protecting sealing materials and preventing leakage.
Application Scope:
Suitable for the lubrication of turbocharged heavy-duty diesel engines requiring CJ-4 grade diesel engine oil, especially suitable for heavy-duty trucks operating on highways.
