Blue Ribbon Exhaust/Soot Control is an API CK-4 universal fleet engine oil developed for use in four-stroke cycle diesel engines.Designed to meet 2017 on-highway exhaust emission standards.Specially formulated to protect exhaust aftertreatment devices. This includes diesel particulate filters (DPFs) and diesel oxidation catalysts (DOCs).Backward serviceable for use in earlier model diesel engines where API CJ-4, CI-4+, CI-4, CH-4, CG-4 or CF-4 oils are specified.Designed for use in mixed fleets with both on-highway and off-road  equipment operating in varying climates and under varying loads and service conditions.Excellent soot dispersency to protect against soot-induced oil thickening and abrasive wear.Excellent oxidation resistance to help minimize deposit formation.The low-ash formula makes it compatible with all exhaust emission control systems in modern diesel engines. It also helps prolong DPF life.For applications not using Ultra-Low Sulfur Diesel (ULSD), consult the engine manufacturer for recommended service interval.
