Functional Fluid, Lubricant, Grease (including Additives)

Lucas SAE 1OW-30 Synthetic Blend CK-4 is a premium Heavy Duty Motor Oil blended with high quality API Group II and Group Ill base oils and a cutting-edge additive package providing the robust performance required by modern diesel engines while assuring good fuel economy. Much improved oxidation resistance means this oil lasts longer and protects engines better than previous heavy duty motor oils. Lucas SAE 1OW-30 Synthetic Blend CK-4 is fully backward compatible with previous standards CJ-4 and Cl-4; specially formulated for modern Ultra-Low Sulfur Diesel Fuel and engines equipped with Diesel Particulate Filters (DPF) and utilizing Diesel Exhaust Fluid (DEF) to control particulates and nitrous oxides. Lucas SAE 1OW-30 Synthetic Blend CK-4 provides excellent soot control and TBN retention as well as shear stability. The 1OW-30 viscosity grade is recommended by most OEMs on recent model years. Lower in viscosity than traditional 15W·40 to improve fuel economy, yet still providing strong film strength and good boundary lubrication to protect vital engine components. May be used safely as a fuel saving alternative to CJ-4 SAE 15W-40.
