Viscosity Control

Formulated with greater than 50% synthetic content to minimize viscosity change

Keeps soot particles suspended independently, helping prevent formation of larger, wear-causing particles

Excels in Extreme Temperatures

Formulated to deliver improved heat and oxidation resistance compared to other synthetic-blend and conventional diesel oils

Provides clean engine operation and helps maintain power and fuel efficiency                                                                                                                 

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.
