AMSOIL DOMINATOR Competition Diesel Oil Has the Power to Protect

AMSOIL has been the Official Oil of the Diesel Power Challenge and Ultimate Callout Challenge since their inception, and has been heavily involved in the turbodiesel pickup world, whether they be daily drivers on the street or a totally hot race truck on the track. AMSOIL has  products for both ends of the spectrum.

• Wear Protection
  Racing and high-performance diesel engines are modified to deliver maximum horsepower and torque. Their powerful designs create shearing forces that can cause oils to lose viscosity, leaving bearings, pistons and other components vulnerable to wear and failure. DOMINATOR 20W-50 Competition Diesel Oil delivers 50 percent more film thickness* to withstand high cylinder pressures and protect against wear. It is heavily fortified with zinc and phosphorus anti-wear additives to provide additional protection against scuffing and wear in severe conditions.

• Viscosity Control
  High-horsepower diesel engines push a lot of fuel, leading to fuel dilution. Fuel reduces the oil’s viscosity. As the oil becomes thinner, it compromises the lubrication of critical components, increasing wear. DOMINATOR Competition Diesel Oil’s robust formulation helps offset the damaging effects of fuel dilution by maintaining its protective viscosity longer.
• Withstands Turbocharger Heat
  Over time, turbos can suffer reduced performance or catastrophic failure. DOMINATOR Competition Diesel Oil is designed with an extremely durable 20W-50 synthetic formulation that contains maximum levels of oxidation-inhibitor additives to resist harmful oxidation and provide exceptional resistance to deposit formation, preserving turbocharger performance and life.
