AMSOIL Inc. of Superior, Wis., has introduced its new Synthetic 5W-40 Premium Diesel Oil. This is a premium diesel oil for model year 2007 and newer heavy-duty and pickup truck diesel engines requiring API CJ-4 emission quality oil standards.

Formulated with the latest additive technology and the most advanced synthetic base oils, AMSOIL Synthetic 5W-40 Premium Diesel Oil exceeds the higher performance demands of modern engines. The product 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.
AMSOIL 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. The new 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 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.
