Application of CI-4 10W-40 Diesel Engine Oil
Applications
CI-4 10W-40 Diesel Engine Oil is suitable for a wide range of medium and heavy-duty diesel engines, including:
Heavy-duty trucks and commercial fleets
Construction and mining equipment
Agricultural machinery such as tractors and harvesters
Power generation systems and industrial diesel engines
Recommended for engines requiring API CI-4 performance level, providing reliable protection under high-load and high-temperature conditions.
Which Engines Need CI-4 15W-40?
CI-4 15W-40 is ideal for heavy-duty applications including fleets, off-road machinery, long-haul trucks, and power generators operating in high-load or variable temperature environments.
CI-4 vs CF-4 Diesel Engine Oil
Compared with CF-4 diesel engine oil, CI-4 provides better soot control, improved wear protection,and longer oil drain intervals. It is more suitable for modern diesel engines operating under
high load, high temperature, and severe working conditions.
