AMSOIL DOMINATOR 20W-50 Competition Diesel Oil - DCO
AMSOIL DOMINATOR® 20W-50 Competition Diesel Oil is designed for professionals and enthusiasts who want a step up in diesel protection. It is specifically designed for high-horsepower diesel engines and delivers the benefits most important to diesel competitors, including robust durability, outstanding bearing protection and the ability to withstand the extreme pressures and temperatures common to diesel competition.
Whether competing in sled pulls, drag races or dyno challenges, competitors using DOMINATOR Competition Diesel Oil enjoy the confidence and security that come with providing their diesel trucks maximum protection and performance.
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.
*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 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.
APPLICATIONS
Use in performance-modified diesel engines that require any of the following specifications:
- API CK-4, CJ-4, CI-4+, CH-4
- Cummins 20081/20086
- Mack EO-O/EOS-4.5
- Volvo VDS3/VDS4/VDS4.5
- Caterpillar ECF-2, ECF-3, ECF-1-a
- Renault RLD-3/RLD-4
- Chrysler MS 10902
- Ford WSS-M2C171-F1
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
the 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 OEM1 drain intervals or extend drain intervals with oil analysis.
1Refer to your owner's manual for OEM drain interval recommendations and guidelines for severe and normal service.
