Exceeds Emission System Requirements

AMSOIL Synthetic 15W-40 Diesel Oil is a low-sulfated ash formulation that provides excellent performance in low-emission diesel engines. It is compatible with all exhaust treatment devices and is designed to extend the service life of diesel particulate filters (DPF).


Extended Drain Performance

AMSOIL Premium 15W-40 Diesel Oil can extend drain intervals far beyond those recommended for conventional petroleum oils. Its unique synthetic formulation and long drain additive system (10.4 TBN) deliver superior engine protection, cleanliness and performance over extended drain intervals. AMSOIL Synthetic 15W-40 Diesel Oil provides
maximum protection for up to 3X the OEM-recommended drain interval, and further with oil analysis.


Controls Soot-Thickening and Wear

The advanced synthetic base oils in AMSOIL 15W-40 Diesel Oil are naturally resistant to soot contamination. That, along with a heavy fortification of 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.


Superior Shear Stability, Reduced Oil Consumption

AMSOIL Synthetic 15W-40 Diesel Oil has lower volatility (burn-off) than conventional petroleum oils. Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Lower volatility helps AMSOIL Premium Diesel Oil retain its viscosity after high-temperature service for continued dependable protection.


Ideal for Fleets

AMSOIL Premium 15W-40 Diesel Oil reduces operating costs through extended drain intervals. It is engineered for a wide range of applications, allowing fleet operators to consolidate engine oil inventories in mixed fleets. In addition, it reduces downtime through extended drain intervals and improved equipment protection.

AMSOIL 15W-40 Diesel Oil costs less per mile than conventional oil
