CI-4 10W-40 is a high-performance heavy-duty engine oil, typically used in modern, high-speed, four-stroke diesel engines. It is designed to handle severe operating conditions, such as high temperatures and heavy loads, while also offering good low-temperature flow for easier cold starts.
Commercial Vehicles:
Used in heavy-duty trucks, buses, and commercial transport vehicles.
Off-Road Equipment: Ideal for construction, agriculture, and mining machinery operating under severe conditions.
Turbocharged and EGR Engines: Formulated to handle the high soot levels and acidity found in engines equipped with Exhaust Gas Recirculation (EGR) systems and turbochargers.
PRODUCT PERFORMANCE
This oil offers high temperature and high shear stability to maintain its viscosity under stress, while providing excellent detergency and dispersancy to keep engines clean by controlling sludge, soot, and piston deposits. It further ensures corrosion protection by neutralizing acidic combustion byproducts to safeguard vital engine surfaces, ultimately allowing for longer drain intervals and extended service for fleets due to its superior thermal stability.
