Terpel Heavy Duty Synthetic Blend 15W-40 CK-4

Terpel Heavy Duty Synthetic Blend 15W-40 CK-4 synthetic technology diesel engine oil is formulated for the protection and lubrication of modern heavy-duty diesel engines operating under demanding working conditions and heavy loads.

Terpel Heavy Duty Synthetic Blend 15W-40 CK-4

Technical characteristics

• Type: Synthetic technology (semi-synthetic / synthetic blend) oil for heavy-duty diesel engines.

• Viscosity grade: SAE 15W-40.

• Service level: API CK-4.

• Superior wear protection: Minimizes friction and protects critical mechanical components under severe loads and high operating temperatures.

• Soot and deposit control: Maintains high detergency and dispersancy to prevent the formation of sludge, varnish, and deposits on pistons.

• Thermal stability and oxidation resistance: Minimizes oil degradation and reduces consumption due to evaporation during extended working hours.

• Compatibility with emission systems: Low ash formulation that protects exhaust after-treatment systems (DPF, EGR, and SCR).

Classifications, specifications and approvals

• International specifications (Meets the requirements of):

  • API CK-4 / CJ-4 / CI-4 Plus / CI-4 / CH-4

  • ACEA E9 / E7

• OEM compatibility / Manufacturer requirements:

  • Cummins CES 20086

  • Detroit Diesel DFS 93K222

  • Mack EOS-4.5

  • Renault Trucks RLD-3

  • Volvo VDS-4.5

  • Caterpillar ECF-3

Applications

• Heavy haul trucks, urban and intercity buses, and commercial fleets.

• Agricultural, construction, mining, and public works machinery.

• Latest generation diesel engines equipped with diesel particulate filters (DPF), exhaust gas recirculation (EGR), and selective catalytic reduction (SCR).

• Turbocharged or naturally aspirated engines requiring API CK-4 specification or backward compatible (CJ-4, CI-4 Plus, CI-4).

Usage recommendation

• Consult the engine manufacturer's manual to verify that SAE 15W-40 viscosity and API CK-4 classification are recommended.

• Replace oil filters at each scheduled drain interval to ensure maximum dispersancy and filtering efficiency.

• Keep containers tightly closed in a clean, dry area protected from the weather.
