Conventional 20W-50 CH-4 Heavy Duty Motor Oil

Our Conventional 20W-50 CH-4 Heavy Duty Motor Oil is designed for high-performance and heavy-duty diesel engines operating under extreme loads and temperatures. Blended with premium base oils and a robust additive system, it offers superior protection against wear, deposits, and oxidation, ensuring consistent performance in demanding conditions.

The multi-viscosity 20W-50 grade provides quick oil flow during cold starts and a strong, protective film at high operating temperatures. This makes it ideal for hot climates, severe-duty applications, and older engines requiring higher viscosity oil for proper lubrication.

Certified to API CH-4 standards, this oil is suitable for engines meeting 1998 emission requirements and earlier. It provides enhanced soot control to reduce abrasive wear, extend oil life, and keep engines running cleaner. Designed for use in turbocharged and naturally aspirated diesel engines, it also offers excellent thermal stability for prolonged service intervals.

Key Benefits:

• Superior protection for heavy-duty diesel engines under severe service

• Excellent high-temperature stability and oxidation resistance

• Advanced detergency to reduce sludge and deposits

• Enhanced soot handling for cleaner engine performance

• Ideal for hot climates, towing, and older engines requiring higher viscosity

The trusted choice for fleets, construction, agricultural, and industrial equipment where 20W-50 CH-4 heavy-duty motor oil is recommended.
