AMSOIL Commercial-Grade Diesel Oil is an advanced synthetic-blend oil with greater than 50% synthetic content. Specially engineered for commercial equipment, it provides 2X better wear protection, helping you keep trucks and equipment operating at peak performance. AMSOIL Commercial-Grade Diesel Oil provides outstanding value and excellent protection for customers seeking an upgrade over conventional diesel oils.

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.

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. AMSOIL Commercial-Grade Diesel Oil also 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.
