LUBRIGUARD FULL SVNTHETIC SAE 5W-40 CK-4/SN HEAVY DUTY DIESEL ENGINE OIL

LUBRIGUARD FULL SVNTHETIC SAE 5W-40 CK-4/SN HEAVY DUTY DIESEL ENGINE OIL is designed for high-speed four-stroke cycle diesel engines meeting 2017 on-highway and Tier 4 non-road emission standards, including older models. It supports diesel fuels with sulfur content up to 500 ppm and offers enhanced protection against oil oxidation, viscosity loss, oil aeration, catalyst poisoning, particulate filter blocking, engine wear, piston deposits, and degradation of low- and high-temperature properties. It also prevents viscosity increase due to soot accumulation.
