15W40 API CI4-Plus

15W40 CI4 Plus grade is the super-premium quality diesel engine oil made from the finest paraffin base stocks and state of art additive technology, specifically designed to address the operational severity and engine durability issues of the modern emission compliant diesel engines, employing Exhaust Gas Recirculation (EGR) & Cooled EGR.

SML provides optimum protection for control of soot handling in cooled EGR, corrosive wear tendencies, piston deposit control, valve train wear, oxidative thickening, foaming and viscosity loss due to shear.


15W40 CI4 Plus grade is recommended for new generation BS IV Diesel Engines of Heavy Commercial, Multi Utility as well as Small Cars requiring highest quality Engine Oils, where Exhaust Gas Recirculation (EGR) /Cooled EGR/SCR type exhaust emission components are used. The product also yields tangible benefits on better engine health, long engine oil Life in regular BS II/BS III type Turbo-charged engine not employing an EGR.
