Delo 400 Multigrade SAE 15W-40

Delo® 400 Multigrade is a premium performance, multigrade, heavy-duty diesel engine oil specifically designed to lubricate a wide range of diesel engines requiring API CI-4 PLUS, CI-4, ACEA E7 or JASO DH-1 performance lubricants operating under the most severe service conditions. 


  • Minimized fleet maintenance costs
    Exceptional soot dispersancy keeps fuel soot in suspension, avoiding filter plugging, cylinder head sludge, abrasive polishing wear and oil thickening. 

  • Minimized fleet operating costs
    Excellent deposit control on valves and piston crownlands reduces oil consumption. Exceptional oxidation stability and soot control extends oil drain capability so that equipment is in service longer generating revenue. Outstanding valve train wear protection maintains fuel economy. 

  • Extended engine life to overhaul
    High level of anti-wear additive protects against valve train wear and scuffing of highly loaded parts operating under boundary lubrication conditions. 


  • Delo ® 400 Multigrade is specifically designed for the electronically controlled diesel engines, including those fitted with EGR and/or SCR systems


  • Mixed fleets of European, North American and/or Japanese diesel engines (high speed, four-stroke, turbocharged or naturally aspirated)

  • Mixed fleets of both diesel and gasoline engines 

  • Mixed fleets including both old and new equipment
