Product Description
KATMOTO HD PRO CI-4 20W-50 is a high-viscosity, high-temperature heavy-duty diesel engine oil meeting API CI-4 for older and high-mileage diesel engines operating under heavy load and in hot climates. Its high 20W-50 viscosity maintains a strong oil film in worn engines, with high-TBN acid control, robust soot handling and strong wear and deposit protection for durable performance in severe-duty operation.
Key Performance Features
| Strong high-temperature film
high 20W-50 viscosity maintains a robust film in hot, heavy-load diesels. |
High-TBN acid control
high reserve alkalinity neutralises combustion acids for long life. |
| Worn-engine protection
high viscosity helps protect worn, high-mileage diesel engines. |
Robust soot handling
strong dispersancy controls soot thickening in older EGR diesels. |
| Hot-climate & heavy-load
ideal for hot climates and severe-duty diesel operation. |
Deposit & wear protection
keeps engines clean and protects liners, bearings and valvetrain. |
Applications & Performance Level
| Applications | Older and high-mileage heavy-duty diesel engines operating under heavy load or in hot climates where SAE 20W-50 API CI-4 oil is specified, including severe-duty and high-temperature operation. |
| Specification | API CI-4 / CH-4 — heavy-duty diesel categories for older and EGR diesel engines. ACEA E7-type — high-SAPS heavy-duty performance for non-DPF diesel engines. Cummins CES 20078 · Mack EO-N — suitable for Cummins and Mack older diesel specifications. Volvo VDS-3 · MB 228.3 — suitable for Volvo VDS-3 and Mercedes-Benz 228.3 applications. Hot-climate / high-mileage — formulated for severe-duty, high-temperature diesel operation. |
| OEM Suitability | Older and high-mileage Cummins, Mack, Volvo, Mercedes-Benz and Caterpillar diesel engines in hot climates specifying SAE 20W-50 API CI-4. Use only where SAE 20W-50 CI-4 is specified by the manufacturer. |
| Important Notice | Use only where the engine manufacturer specifies SAE 20W-50 and a matching performance level. ”Suitable for” does not mean official approval unless an approval license or certificate is separately issued. |
