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 — based on the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222, using 10W-30 as the worst-case representation — to help maximize equipment life and reduce maintenance costs and downtime.
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, and flows 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.
