Key Highlights
API CH-4 · SAE 20W-50 · Heavy Duty Diesel Oil · Suitable for Traditional Diesel Engines
YEFE API CH-4 20W-50 Diesel Engine Oil is formulated for heavy-duty diesel engines that require high-viscosity lubrication for operation under high temperatures and heavy load conditions. Designed for older-generation diesel engines, this formulation offers reliable wear protection, soot control, and oil stability during routine commercial use.
The SAE 20W-50 viscosity grade provides enhanced oil film strength, making it suitable for high-temperature operation and heavy-duty vehicles. This product is ideal for standard oil change intervals in older engines and is commonly used in trucks and commercial vehicles operating under demanding conditions.
