Heavy-Duty Motor Oil
Delo® 400 SLK Syn-Blend SAE 10W-40
Delo® 400 SLK SAE 10W-40 with ISOSYN Advanced Technology is a premium quality “low-SAPS” heavy-duty diesel engine oil specifically designed to lubricate a wide range of high-speed diesel engines requiring API CK-4, CJ4, CI-4 PLUS or ACEA E9 performance lubricants operating under severe service conditions.
*Our Product Data Sheets (PDS) contain product information including features, benefits, applications, typical key properties and service considerations. PDSs are produced regionally based on the best available information at the time of issue. For each product, there is one PDS for the Asia Pacific region. The specific information included in each PDS may not directly reflect the Australian market or Australian conditions. In the event of any inconsistency between this webpage and the applicable PDS, this webpage prevails. For the most up-to-date, Australian-specific information contact us.

- Minimises operating costs
Exceptional soot dispersancy keeps soot in suspension, helps minimizing filter plugging, cylinder head sludge, abrasive polishing wear and oil thickening. Robust wear and corrosion protection of engine components due to effective antiwar additive system. Helps improve equipment durability and reliability while reducing equipment downtime.
- Improved efficiency and low temperature protection
Improved low temperature fluidity helps reduce energy consumption at start-up and protects engine components from wear and tear by reaching critical components faster.
- Maintain emission control system performance
Formulated with latest generation “low-SAPS” (sulfated ash, phosphorus and sulfur) technology helps maximizes the life of sensitive catalyst metals and the cleaning intervals of diesel particulate filters.
- Reduces inventory costs
Balanced formulation provides excellent overall performance in mixed fleets of different engine designs, (including modern low emission diesel engines) allowing one oil for many services and helping reduce the chance of product misapplication. Backward compatible with previous API Oil Service Categories and engine models.
