Amsoil Diesel Motor Oil

Amsoil diesel oils are  Advanced synthetic technology provides excellent viscosity control and  outstanding extreme-temperature performance, while minimizing oil  consumption. The result: protection that’s boosted to the max. 

 Amsoil Provides Maximum 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 Signature Series Max-Duty delivers 6X more wear protection*, delivering the security of providing your diesel the extra protection it deserves. 

 AMSOIL 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. 

Amsoil  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. 

 AMSOIL Heavy-Duty Synthetic Diesel Oil is formulated for hardworking  equipment. It is engineered to provide 4X better wear protection1, giving you the edge to keep trucks and equipment operating at peak performance. 

 AMSOIL  Heavy-Duty Synthetic Diesel Oil is formulated for hardworking equipment.  It is engineered to provide 4X better wear protection1,  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.
