Heavy Duty Engine Oil (HDEO)

Super DEO 10W-30 CK-4

Premium Heavy Duty Diesel Engine Oil


Nemco Super Blue 15W-40 and 10W-30 are API CK-4 approved engine oils developed for use in fourstroke cycle diesel engines that meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards, as well as for previous model year engines. These oils are especially formulated to protect and sustain engine exhaust after-treatment devices such as diesel particulate filters (DPFs), diesel oxidation catalysts (DOCs) and selective catalytic reduction (SCR) systems.

Super Blue 15W-40 and 10W-30 are backward serviceable for use in pre-2017 diesel engines, and may be used in older equipment that called for earlier API oil categories such as CJ-4, CI-4 with CI-4 Plus, CI-4 and CH-4. These oils are 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. They have excellent soot dispersancy to protect against soot-induced oil thickening and abrasive wear, and excellent oxidation resistance to help minimize deposit formation. The low-ash formulation is designed for compatibility with all exhaust emission control systems in modern diesel engines, and to help prolong DPF life.
