• Has ample reserves to cope with extended oil change intervals.
  • Enhanced anti-wear characteristics.
  • Provides effective protection against piston ring wear, rust and bearing corrosion.
  • Optimised cold start and fast warm-up.
  • Good oxidation resistance and reduced varnish, lacquer, sludge and carbon deposit formation even in severe service operation.
  • High lubricating oil film strength protects heavily loaded valve train gears.
  • Protects against bore polishing, scuffing and minimizes cylinder liner wear.
  • Excellent dispersancy retains soot and harmful oxidized products in suspension, aids filterability.
  • Good reserve alkalinity retention effectively neutralizes harmful acidic combustion contaminants and prevents premature wear in pro-longed oil service interval.
  • Good viscosity-temperature behaviour due to stay in grade characteristics even in very severe conditions.
  • Does not attack rubber gaskets, hoses and other sealing materials.
  • Low foaming.
  • Low evaporation loss and low ash levels combine to reduce particulate emissions.

  • AC Delco Select 10W40 is recommended for major US, European and Japanese diesel engines such as Caterpillar, Cummins, Detroit Diesel Allison, Volvo, MAN B&W, MTU, Duetz, Wärtsilä, MB, Komatsu, Hino and others.
  • Developed for highly stressed normally aspirated and turbocharged engines with exhaust gas recirculation (ERG) system.
  • Ideal all-season oil for mixed fleets, construction and earth moving equipment, marine ferries and industrial equipment with diesel engines.
