API CH-4 20W-50 Heavy Duty Diesel Engine Oil
API CH-4 20W-50 Heavy Duty Diesel Engine Oil
A high-viscosity 20W-50 diesel engine oil designed for traditional heavy-duty diesel engines operating in high-temperature environments.
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 operating under high temperature and heavy load conditions. Designed for older-generation diesel engines, this oil provides stable lubrication performance, reliable wear protection, and effective soot control during routine commercial operation.
The SAE 20W-50 viscosity grade delivers enhanced oil film strength compared to lower viscosity grades, making it suitable for engines operating in hot climates or under demanding service conditions. It is recommended for vehicles following standard oil change intervals.
Packaging & Branding Support
YEFE offers affordable and adaptable customization solutions based on the package solutions and branding presentation that distributors and brand owners can introduce lubricant products easily and in a professional manner.
We plan to offer our customization services as a way of minimizing time-to-market with no compromise in the quality of the products and supply reliability.

This API CH-4 20W-50 diesel engine oil is engineered to maintain stable viscosity performance under elevated temperatures. The higher viscosity grade supports stronger oil film thickness, helping to reduce wear in engines subjected to heavy loads and prolonged operation.
The formulation is suitable for diesel engines without advanced emission aftertreatment systems and is commonly used in older heavy-duty trucks and commercial vehicles operating under conventional maintenance schedules.
