Protection Engineered to Perform
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.
Key Benefits
- AMSOIL x Fleece Performance Engineering co-branded formulation
- Excellent turbo cleanliness
- Superior soot control
- Outstanding wear protection in demanding operating conditions
- Contains no wax; stays fluid in sub-zero temperatures for easier starting
- Resists thermal (heat) breakdown and oxidation
- Low volatility reduces oil consumption during operation
- Retains viscosity after high-temperature service
Proven Performance
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 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.
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.
