Helps minimize operating costs
Delo® 400 SLK is designed to provide exceptional soot dispersancy to help keep soot in suspension, and to assist with minimizing filter plugging, cylinder head sludge, abrasive polishing wear and oil thickening. It is formulated with an effective antiwear additive system to help provide robust wear and corrosion protection of engine components, helping to improve equipment durability and reliability while reducing equipment downtime.
Formulated to help maintain emission control system performance
Low Sulfated Ash, Phosphorous and Sulfur (SAPS) technology, helps maximize the life of sensitive catalyst metals and extend the cleaning intervals of diesel particulate filters (DPFs).
Helps reduce inventory costs
Proprietary formulation is designed to provide 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. Please refer to owner’s manual for more details.
