Product Description
KATMOTO HD PRO CI-4 15W-40 is a robust heavy-duty diesel engine oil meeting API CI-4 for older and mixed-fleet diesel engines, including EGR-equipped engines. Its high-TBN, high-detergency formulation delivers excellent soot handling, acid neutralisation, wear and corrosion protection and deposit control for durable performance and long engine life in demanding and high-mileage diesel applications.
Key Performance Features
| High-TBN acid control
high reserve alkalinity neutralises combustion acids for long engine life. |
Robust soot handling
strong dispersancy controls soot thickening in older EGR diesel engines. |
| Wear & corrosion protection
protects liners, bearings and valvetrain under heavy load. |
High-temperature deposit control
keeps pistons and rings clean under demanding operation. |
| Mixed-fleet versatility
suitable for older diesel and many gasoline mixed fleets. |
Durable, high-mileage protection
dependable protection for high-mileage and severe-duty engines. |
Applications & Performance Level
| Applications | Older and mixed-fleet on- and off-highway heavy-duty diesel engines, including EGR engines without DPF, where SAE 15W-40 API CI-4 oil is specified. |
| 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. MAN M3275 · Cat ECF-2 — suitable for MAN and Caterpillar older diesel specifications. |
| OEM Suitability | Older and mixed-fleet Cummins, Mack, Volvo, Mercedes-Benz, MAN and Caterpillar diesel engines specifying SAE 15W-40 API CI-4. Use only where SAE 15W-40 CI-4 is specified by the manufacturer. |
| Important Notice | Use only where the engine manufacturer specifies SAE 15W-40 and a matching performance level. ”Suitable for” does not mean official approval unless an approval license or certificate is separately issued. |
