Product Description
KATMOTO HD MAX CK-4 15W-40 is a high-performance heavy-duty diesel engine oil meeting API CK-4 for modern low-emission on- and off-highway diesel engines fitted with EGR, DPF and SCR after-treatment. Its robust additive system delivers outstanding soot dispersancy, wear and corrosion protection, oxidation and thermal stability and high-temperature deposit control, supporting long drain intervals while remaining backward compatible with CJ-4/CI-4 applications.
Key Performance Features
| Outstanding soot control
advanced dispersancy controls soot-related thickening and wear in EGR diesels. |
After-treatment compatible
low-SAPS (ash ≤ 1.0%) protects DPF and SCR systems in modern diesels. |
| Wear & corrosion protection
strong anti-wear and acid-neutralising performance for long engine life. |
Oxidation & thermal stability
resists oil thickening and deposits under high-load, high-temperature duty. |
| Extended drain capability
stable performance supports OEM-recommended long drain intervals. |
Backward compatible
suitable for CJ-4 and CI-4 diesel applications. |
Applications & Performance Level
| Applications | Modern on- and off-highway heavy-duty diesel engines (trucks, buses, construction and agricultural equipment) fitted with EGR, DPF and SCR after-treatment where SAE 15W-40 API CK-4 oil is specified. |
| Specification | API CK-4 / CJ-4 / CI-4 — current heavy-duty diesel category and backward compatibility. ACEA E9-type — mid-SAPS heavy-duty performance for after-treatment-equipped diesels. Cummins CES 20086 · Detroit DFS 93K222 — suitable for Cummins and Detroit modern diesel specifications. Volvo VDS-4.5 · Mack EOS-4.5 — suitable for Volvo and Mack heavy-duty diesel applications. Cat ECF-3 · MB 228.31 · MAN M3575 — suitable for Caterpillar, Mercedes-Benz and MAN diesel specifications. |
| OEM Suitability | Modern Cummins, Detroit, Volvo, Mack, Caterpillar, Mercedes-Benz, MAN, DAF and Paccar diesel engines specifying SAE 15W-40 API CK-4. Use only where SAE 15W-40 CK-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. |
