CI-4 10W-30, 10W-40, 15W-40, and 20W-50 diesel engine oil series products
Short Description:
Product Overview:
This product is formulated with highly refined high-viscosity index base oils, hydrotreated base oils, and high-quality multifunctional additives.
Performance Characteristics:
• Excellent anti-wear properties, providing effective protection for top-tier environmentally friendly diesel engines using technologies such as exhaust gas recirculation (EGR);
• Excellent acid neutralization performance, preventing rust and corrosive wear of engine components;
• Superior high-temperature oxidation resistance, reducing the impact of high-temperature sludge and deposits on engine corrosion and wear;
• Good rubber compatibility, effectively protecting sealing materials and preventing leaks.
Application Scope:
Suitable for the lubrication of turbocharged heavy-duty diesel engines requiring CI-4 grade diesel engine oil, especially suitable for heavy-duty trucks operating on highways.
