New DOMINATOR® Competition Diesel Oil

Everyone is talking about this one – well OK, but I’m sure a few are..  These engines pose problems which causes much more to be desired with the oil so AMSOIL once again calls it spot on!! Resists the breakdown from high levels of soot!!

The newest addition to the DOMINATOR racing line is specially formulated for performance-modified diesel engines.

New AMSOIL DOMINATOR® 20W-50 Competition Diesel Oil (DCO) is engineered for modified, competition diesel engines and the high-horsepower demands of sled pulling, dyno runs and drag racing. Fortified with 50 percent better resistance to oil breakdown* to withstand high cylinder pressures, and jacked with extra zinc and phosphorus for bulletproof wear protection, DOMINATOR Competition Diesel Oil provides professionals and enthusiasts with the power, protection and confidence needed to win.

  • Competition-grade technology formulated specifically to deliver maximum power and protection in performance-modified diesel engines
  • Extra zinc and phosphorus for bulletproof wear protection
  • Fights oil breakdown under the extreme temperatures and pressures of competition, extending the lives of cylinders, rings, cranks, rods, turbochargers and bearings
  • High-viscosity formulation provides an extra level of protection, while offsetting the negative effects of fuel dilution
  • Delivers superior shear stability to withstand the intense stress and compression common to high-horsepower diesel trucks
  • May be used in any diesel engine calling for an API CK-4, CJ-4, CI-4+ or CH-4 diesel oil
