Product Description
Treat your diesel right with Freedom Series 100% Synthetic Diesel Oil. Freedom Series emerged when AMSOIL and Fleece Performance Engineering partnered to develop an advanced formulation for diesel pickup trucks equipped with Fleece Performance products. Freedom Series Synthetic Diesel Oil provides excellent turbo cleanliness, superior soot control and outstanding wear protection. The result: protection engineered to perform.

Outstanding Engine Protection
Wear on rings and cylinder liners leads to increased oil consumption and loss of compression, resulting in reduced horsepower and fuel economy. Freedom Series Synthetic Diesel Oil is formulated to deliver outstanding wear protection in demanding operating conditions, maximizing the life of your diesel pickup and reducing maintenance costs and downtime.

Soot Control
Soot buildup in a diesel pickup can reduce power, increase abrasion, cause emissions-system problems and decrease fuel economy. Freedom Series Synthetic Diesel Oil is naturally resistant to oxidation and the thickening effects of soot contamination. That, along with boosted detergent/dispersant additives, keeps soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Viscosity increase is minimized and soot related wear is controlled. Lower volatility also helps Freedom Series retain its viscosity after high temperature service for maximum engine protection and efficiency.

Excels in Extreme Temperatures
Freedom Series Synthetic Diesel Oil effectively resists thermal (heat) breakdown. Unlike conventional oils, Freedom Series contains no wax, staying fluid in sub-zero temperatures for easier starting, improved oil flow and reduced wear, making it excellent for use in both hot-operating engines and cold-weather starting extremes.

Minimizes Oil Consumption
Freedom Series Synthetic Diesel Oil has a low rate of volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber.

Turbo Cleanliness
Freedom Series Synthetic Diesel Oil provides the turbo cleanliness needed to support reliability when towing, hauling or modifying for additional horsepower.

COMPATIBILITY
Freedom Series Synthetic Diesel Oil is compatible with other conventional and synthetic engine oils. Mixing AMSOIL diesel oil with other oils, however, will reduce its performance benefits.

Aftermarket oil additives are not recommended for use with AMSOIL synthetic diesel oils.

SERVICE LIFE
Turbodiesel Pickup: Recommended for the drain intervals stated by the vehicle manufacturer. Refer to the owner’s manual for the specific oil change interval.

Competition Service Life: When competing, the vehicle owner is responsible for determining the appropriate service interval.
