Outstanding Protection for Smaller Diesel Engines
AMSOIL 100% Synthetic Diesel Oil 0W-20 is specifically formulated to protect the efficient diesel power of American diesel pickups, vans, cars and SUVs, giving you the edge to keep your vehicle operating at peak performance. It delivers outstanding value and excellent protection for customers seeking an upgrade over conventional, synthetic-blend or competing synthetic diesel oils.
Key Benefits
- Up to 6X more wear protection than required by a leading industry standard
- Strong fluid film and robust anti-wear additives protect camshaft lobes for maximum engine life
- Keeps soot particles suspended independently to help prevent larger, wear-causing particles
- Lower volatility helps retain viscosity after high-temperature service for added engine protection and fuel economy
- Improved heat and oxidation resistance compared to conventional diesel oils
- Flows dependably in cold temperatures for easier startup and improved engine protection
- Low volatility (burn-off) reduces oil consumption during operation
- Safe for diesel emissions systems
Proven Performance
Outstanding Engine Protection. Wear on camshaft lobes can negatively impact valve timing, leading to loss of horsepower and fuel economy. AMSOIL 100% Synthetic Diesel Oil's strong fluid film keeps metal surfaces separated, while its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. Third-party testing shows AMSOIL 100% Synthetic Diesel Oil delivers up to 6X more wear protection than required by a leading industry standard.
Viscosity Control. Formulated with advanced synthetic base oils and detergent/dispersant additives, AMSOIL 100% Synthetic Diesel Oil minimizes viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Lower volatility also helps in retaining its viscosity after high-temperature service for added engine protection and increased fuel economy.
Excels in Extreme Temperatures. AMSOIL 100% Synthetic 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 superior engine performance. AMSOIL Synthetic Diesel Oil also flows dependably in cold temperatures for easier startup and improved engine protection.
Minimizes Oil Consumption. AMSOIL 100% Synthetic Diesel Oil has low volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber. It is safe for diesel emissions systems.
