Heavy-Duty Synthetic Diesel Oil 5W-40
AMSOIL Heavy-Duty Synthetic Diesel Oil 5W-40 is formulated for hardworking equipment. It is engineered to provide 4X better wear protection, giving you the edge to keep trucks and equipment operating at peak performance.
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 Heavy-Duty Synthetic Diesel Oil delivers 4X more wear protection1 to help maximize equipment life and reduce maintenance costs and downtime.
Formulated with advanced synthetic base oils and detergent/dispersant additives, AMSOIL Heavy-Duty Synthetic Diesel Oil 5W-40 minimizes viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Lower volatility also helps Heavy-Duty Synthetic Diesel Oil retain its viscosity after high-temperature service for added engine protection and increased fuel economy.
Excels in Extreme Temperatures
AMSOIL Heavy-Duty Synthetic Diesel Oil 5W-40 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 Heavy-Duty Synthetic Diesel Oil also flows dependably in cold temperatures for easier startup and improved engine protection.
Minimizes Oil Consumption
AMSOIL Heavy-Duty 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. It provides up to 66 percent less oil consumption than required by the API CK-4 standard in the Caterpillar-1N oil consumption test.

All viscosities capable of gasoline service API SN; consult owner’s manual for proper viscosity recommendation.
AMSOIL Heavy-Duty Synthetic Diesel Oil 5W-40 is compatible with other conventional and synthetic 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.
AMSOIL Heavy-Duty Synthetic Diesel Oil is recommended for the drain intervals stated by the original equipment manufacturer (OEM). Refer to the owner’s manual for the specific oil change interval. Intervals may be extended beyond the EM-recommended interval with oil analysis. Provides lasting protection for multiple events during competition. Use oil analysis to determine appropriate drain intervals for competition use or when extending drain intervals beyond the OEM recommendation.
