Heavy-Duty Engine Protection

Wear on rings and cylinder liners leads to increased oil consumption and loss of compression, resulting in reduced horsepower and fuel economy. Third-party testing shows AMSOIL Commercial-Grade Diesel Oil delivers 2X more wear protection* to help maximize equipment life and reduce maintenance costs and downtime.


*Based on third-party testing in the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222 using 10W-30 as worst-case representation.


Viscosity Control

Formulated with greater than 50% synthetic content and high-performance detergent/dispersant additives, AMSOIL Commercial-Grade Diesel Oil minimizes viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles.


Excels in Extreme Temperatures

AMSOIL Commercial-Grade Diesel Oil is formulated to deliver improved heat and oxidation resistance compared to conventional diesel oils. It provides clean engine operation and helps maintain power and fuel efficiency for strong engine performance. AMSO L Commercial-Grade Diesel Oil also fows dependably in cold temperatures for reliable startup and engine protection.


Minimizes Oil Consumption

AMSOIL Commercial-Grade Diesel Oil has a low rate of volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber. This contributes to fewer combustion-chamber deposits and longer aftermarket-system 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

AMSOIL Commercial-Grade Diesel Oil is recommended for the drain intervals stated by the original equipment manufacturer (OEM) Refer to the owners manual for the specific oil change interval. Intervals may be extended beyond the OEM- recommended interval with oil analysis.
