AMSOIL Heavy-Duty Synthetic Diesel Oil is formulated for hard- working equipment. It is engineered to provide 4X better wear protection,1 giving you the edge to keep trucks and equipment operating at peak performance. AMSOIL Heavy-Duty Synthetic Diesel Oil offers outstanding value and provides excellent protection for customers seeking an upgrade over conventional, synthetic-blend or competing synthetic diesel oils.
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 protection than required by the Detroit Diesel DD13 Scuffing Test for Specification DFS 93K222, delivering extra protection so you can push your diesel with peace of mind.
Signature Series Max-Duty Diesel Oil provides up to 76 percent less oil consumption than required by the API CK-4 standard in the Caterpillar-1N oil consumption test.
Formulated with advanced synthetic base oils and detergent/dispersant additives, AMSOIL Heavy-Duty 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 AMSOIL Heavy-Duty Synthetic Diesel Oil retain its viscosity after high-temperature service for added engine protection and increased fuel economy.
AMSOIL Heavy-Duty 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 Heavy-Duty Synthetic Diesel Oil also flows dependably in cold temperatures for easier startup and improved engine protection.
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.

AMSOIL Heavy-Duty Synthetic Diesel Oil is compatible with other conventional and synthetic oils. Mixing AMSOIL diesel oil with other oils, however, will reduce its performance benefits.
AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL synthetic motor 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 OEM- recommended interval with oil analysis. Provides lasting protection for multiple events during competition. Use oil analysis to determine appropriate drain interval for competition use or when extending drain intervals beyond the OEM recommendation.
• For best performance, use AMSOIL Oil Filters AMSOIL Oil Filters stop smaller particles, flow more oil and last longer than regular filters.
