Ultimate Protection for Competition Diesel Engines

Whether competing in sled pulls, drag races or dyno challenges, competitors using DOMINATOR® 20W-50 Competition Diesel Oil enjoy the confidence and security that come with providing their diesel trucks maximum protection and performance.

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 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.

  • 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

Tips to prepare your vehicle for hazardous roads before winter arrives. _by David Hilgendorf |October 2024 Ice storms are most common when the air temperature is close to freezing and blizzards become more likely as temperatures fall below freezing. Both can reduce visibility and create slippery […]

Noack Volatility

Low-Volatility motor oil helps unlock vehicle performance   To meet today’s strict motor oil specifications and adequately protect modern engines, motor oils must demonstrate increased resistance to volatility. Nearly 30 years ago AMSOIL became the first oil manufacturer in the United States to use the NOACK Volatility Test (ASTM D5800) as a measure of performance […]

Do Transmission Fluid Additives Work? John Baker| Feb 26, 2024 9:04 AM Walk the aisles of most auto parts stores and you’ll find multiple “mechanic-in-a-bottle”-type additives that claim to restore transmission performance. The claims made typically include some variation of the following: • Frees stuck valves to improve shifting • Fixes transmission slipping • Restores smooth […]

Understanding Oil Viscosity Viscosity is the measure of a fluid’s resistance to flow. _by David Hilgendorf|January 17, 2023 The physical properties of lubricants are measured by characteristics like viscosity, shear stability, high- and low-temperature performance, water resistance and volatility. Lubrication science seeks to optimize a lubricant’s performance by managing these properties using different base oils […]
