Wear Protection
Wear ProtectionRacing 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.
*compared to the 3.5cP HTHS limit for SAE 15W-40

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 lubricationof 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-50synthetic 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.

Compatibility
DOMINATOR 20W-50 Competition Diesel Oil is
compatible with other conventional and synthetic engine oils. Mixing
AMSOIL diesel oils with other oils, however, will shorten the oil’s
life expectancy and reduce its performance benefits. AMSOIL does not
support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended
for use with AMSOIL synthetic diesel oils.
Service Life
DOMINATOR Competition Diesel Oil provides lasting protection for
multiple events. Use oil analysis to determine appropriate drain
interval.
Note: When not competing, follow
OEM* drain intervals or extend drain intervals with oil analysis.
* Refer to your owner’s manual for OEM drain interval
recommendations and guidelines for severe and normal service.
