AMSOIL Heavy-Duty Synthetic Diesel Oil 15W-40 Formulated for Exceptional Diesel Engine Protection   AMSOIL Heavy-Duty Synthetic Diesel Oil is formulated for hard-working equipment. It is engineered to provide 4X better wear protection than required by the Detroit Diesel DD13 Scuffing Test for Specification DFS 93K222, giving you the edge to keep trucks and equipment operating at peak performance. 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. 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 protection1 to help maximize equipment life and reduce maintenance costs and downtime. Viscosity Control 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. APPLICATIONS Use in diesel engines and, where appropriate, gasoline engines requiring any of the following specifications: API CK-4, CJ-4, CI-4+, CF Volvo VDS4.5, VDS4, VDS3 Mack EOS-4.5, EO-O Renault RLD-4, RLD-3 Cummins CES20086, CES20081 Caterpillar ECF-2, ECF-3, ECF-1-a DDC 93K218, 93K215, 93K214 DFS 93K222 ACEA E9, E7 MB 228.31 MAN 3575 MTU Type 2.1, II, I JASO DH-2 Deutz DQC III-10LA Chrysler MS 10902 Ford WSS-M2C171-F1 All viscosities capable of gasoline service API SN; consult owner's manual for proper viscosity recommendation.
