Super-D® EC Diesel Engine Oil

API CK-4 Diesel Engine OIl for Low-Emission Engines

Kendall® Super-D EC (Emission Compatible) Diesel Engine Oil is an API CK-4 engine oil developed for use in four-stroke cycle diesel engines designed to meet 2007 and later EPA on-highway exhaust emissions standards. It is specially formulated for compatibility with exhaust aftertreatment systems using diesel particulate filters (DPFs), diesel oxidation catalysts (DOCs) and/or selective catalytic reduction (SCR). It is backward serviceable for use in pre-2007 diesel engines.

Features & Benefits

  • Excellent protection for newer low-emission diesel engines and older diesel engines
  • Specially formulated to protect exhaust aftertreatment systems
  • Protects against particulate filter plugging
  • Excellent soot control for protection against abrasive wear and soot-induced oil thickening
  • Excellent resistance to viscosity and thermal breakdown at high temperatures
  • Protects against sludge and varnish formation
  • Protects against rust, bearing corrosion and wear
  • Good resistance to foaming and aeration


  • On-highway diesel trucks equipped with EGR and exhaust aftertreatment systems to meet 2007/2010 emissions standards
  • Older diesel equipment with conventional, non-EGR engines or ACERT engines
  • Off-highway construction, earth moving and mining equipment
