Amsoil Signature Series Max-Duty Synthetic DIESEL Oil 15W-40

Protect your investment in diesel power and confidently extend drain intervals with AMSOIL’s top-grade synthetic diesel oil. AMSOIL Signature Series Max-Duty 15W-40 Synthetic Diesel Oil delivers 6X more wear protection giving your diesel the extra protection it deserves. Advanced synthetic technology provides excellent viscosity control and outstanding extreme-temperature performance while minimizing oil consumption. 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 Signature Series Max-Duty delivers 6X 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. Using top-tier synthetic base oils Signature Series Max-Duty is naturally resistant to oxidation and the thickening effects of soot contamination. That along with boosted 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. Lower volatility also helps Signature Series Max-Duty Diesel Oil retain its viscosity after high temperature service for maximum engine protection and efficiency. Signature Series Max-Duty Synthetic Diesel Oil resists thermal heat breakdown better than conventional and competing synthetic diesel oils. Unlike conventional oils Signature Series contains no wax staying fluid in sub-zero temperatures for easier starting improved oil flow and reduced wear. The result: protection thats boosted to the max.
