Mobil Delvac Modern 15W-40 Full Protection
Synthetic-technology diesel oil for EGR and DPF engines, API CK-4, Cat ECF-3, ACEA E11
SAE 15W-40
Mobil Delvac Ultra 5W-40 Ultimate Protection v1 is an ultimate full synthetic high performance heavy duty diesel engine oil with a low ash formula that helps extend engine life while providing long drain capability and potential fuel economy for modern and latest diesel engine technology operating in severe applications. It delivers exceptional performance in the latest, modern and older, hardworking engines, including those with emission control systems, and is recommended for a wide range of heavy-duty applications in on-road transport and off-road mining, forestry, construction and agricultural industries. Developed to maintain unsurpassed oxidation stability while delivering exceptional low-temperature fluidity and pumpability for smooth starting down to -35°C, its sophisticated additive system ensures exceptional engine wear performance and supports long engine life. The low-ash formulation protects exhaust after-treatment devices, and advanced engine cleanliness performance prevents deposits, keeping the engine running efficiently for longer. Key features include excellent low-temperature pumpability, step-out wear protection, unsurpassed oxidation stability, superb corrosion resistance and an expertly formulated low-viscosity formulation for fuel economy potential. Recommended for the most sophisticated high-performance diesel engines with turbo-charger, direct injection and low-emission designs and all types of exhaust after-treatment technology, for on- and off-highway use, high-performance gasoline engines and mixed fleets. SAE 5W-40, it carries approvals including Detroit Fluids Specification 93K218 and 93K222, MACK EOS-4.5, MTU Oil Category 2.1, VOLVO VDS-4.5, RENAULT TRUCKS RLD-3, Cummins CES 20081/20086 and DEUTZ DQC IV-18 LA, and meets or exceeds API CK-4, CJ-4, CI-4 PLUS, CI-4, CH-4, SM, SN, SL, JASO DH-2, Caterpillar ECF-3, ACEA E7/E11 and ISUZU DEO (w/ DPD equipped vehicles).
