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.
