Synthetic 5W-40 Premium Diesel Oil     

AMSOIL Synthetic 5W-40 Premium Diesel Oil (DEO) is the premium choice diesel oil for model year 2007 and newer heavy-duty and pickup truck diesel engines requiring API CJ-4 emission quality oil standards. It delivers extraordinary lubrication in diesel engines found in commercial, fleet and personal vehicles. Formulated with the latest additive technology and the most advanced synthetic base oils, Synthetic 5W-40 Premium Diesel Oil exceeds the higher performance demands of modern engines. It withstands the stress of heat, soot and acids to help prevent deposits, corrosion and wear, and its broad viscosity range offers superior protection over a wide temperature range. Synthetic 5W-40 Premium Diesel Oil resists breakdown and is recommended for the longest service interval established by the engine, vehicle or equipment manufacturer. Drain intervals may be extended when monitored by oil analysis. AMSOIL Synthetic 5W-40 Diesel Oil is a low sulfated ash, phosphorus and sulfur formulation that meets and exceeds modern specifications for emission quality diesel oil. It is compatible with all exhaust treatment devices and is designed to extend the service life of particulate filters.

AMSOIL Synthetic 5W-40 Premium Diesel Oil replaces 5W-40, 10W-40 and 15W-40 viscosity oils. It is “backwards compatible” with pre-2007 diesel engines and recommended for newer and older diesel and gasoline engines and other applications requiring the following worldwide specifications:

• API CJ-4, CI-4+, CH-4, CF
• API SM, SL, SJ...
• ACEA E7
• Mack EO-O Premium Plus
• DDC Power Guard 93K218
• Caterpillar ECF-3, ECF-1
• Cummins CES 20081
• Volvo VDS-4
• MB 228.3
• MTU Type II

Synthetic 5W-40 Premium Diesel Oil may be used in pre-2007 diesel engines, but for increased protection and performance for extended drain intervals, AMSOIL continues to recommend Synthetic Heavy Duty Diesel& Marine Motor Oil (AME), Series 3000 Synthetic 5W-30 Diesel Oil (HDD) or Synthetic 10W-30/SAE 30 Diesel Oil (ACD).
