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. Independent 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 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 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 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.

AMSOIL Heavy-Duty Synthetic Diesel Oil is compatible with other conventional and synthetic engine oils. Mixing
AMSOIL diesel oils with other oils, however, will reduce the performance benefits.
Aftermarket oil additives are not recommended for use with AMSOIL synthetic diesel
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
