Schaeffer Manufacturing Co. 0700CK4-012 SynShield Durability Advantage 15W-40 Diesel Engine Oil, 12-Quart Bottle (Pack of 12)

Schaeffers SynShield Durability Advantage 15w40 Oil is a premium advanced performance, synthetic plus, heavy-duty diesel engine oil formulated to provide maximum protection against wear, oxidation, deposit formation, soot contamination and aeration. SynShield Durability Advantage 15w40 provides excellent equipment durability and longevity even during harsh, extreme duty operating conditions. Using Schaeffer’s proprietary friction modifiers, Micron Moly and Penetro, SynShield Durability Advantage 15w40 creates a slippery, tenacious shield that prevents metal-to-metal contact. This added layer of durability protection significantly reduces wear on bearings, rings, pistons, cylinders and valve trains. SynShield Durability Advantage 15w40 Engine Oil is suitable for use in 2007 and 2010 emission complaint engines that utilize heavy exhaust gas recirculation (EGR) and exhaust after-treatment devices such as diesel particulate filters (DPFs) with or without diesel oxidation catalysts (DOCs) and selective catalytic reduction (SCR). Schaeffer"s 15w40 diesel oil meets and exceeds API CK-4 specifications.
