Class 8 trucks from Kenworth Truck Company will come factory filled with Chevron Delo 400 XLE Synblend SAE 10W-30 engine oil. Delo 400XLE Synblend is formulated with ISOSYN Technology, Chevron’s exclusive combination of base oil and additives.
The oil, according to the company, is designed to provide wear and soot control protection and to minimize deposit formation in on-highway truck engines using Ultra Low Sulfur Diesel (ULSD). Kenworth’s Class 8 truck assembly plants in Chillicothe, Ohio and Renton, Wash. will offer the oil as standard.
