Phillips 66® Guardol XT Full Synthetic Diesel Engine Oil is a premium quality, full-synthetic engine oil developed for use in 4-stroke cycle diesel engines operating under severe duty service or extreme temperature conditions. It meets API CK-4 performance requirements for use in modern low-emission engines designed to meet 2007 and later EPA on-highway exhaust emissions standards, and is backward serviceable for use in older diesel engines. It is specially formulated for compatibility with exhaust aftertreatment systems using diesel particulate filters (DPF), diesel oxidation catalysts (DOC), and/or selective catalytic reduction (SCR). The full-synthetic formulation provides excellent low-temperature properties for better performance in harsh winter climates.
