This 12-pack of 1-quart bottles of Schaeffer SynShield OTR Plus 5W-40 Full Synthetic Diesel Engine Oil bundled with a 1-pint bottle of Schaeffer Moly EP Oil Treatment provides maximum protection and performance for heavy-duty diesel engines. The SynShield OTR Plus synthetic oil is formulated to prevent wear, oxidation, deposits, soot contamination and aeration. It creates a protective barrier between metal components to increase engine efficiency. It meets API CK-4 specifications and is suitable for 2007 and newer diesel engines with exhaust after-treatment systems. Key features include maintaining fuel economy, superior cold weather performance, high heat tolerance, and keep-clean capability. The Moly EP Oil Treatment contains micron moly and penetro to significantly reduce friction and wear on bearings, rings, pistons, cylinders and valve-trains. When added to engine oil at 1 pint per 4-5 quarts, it increases oil pressure to reduce consumption while controlling viscosity. It can also be used as an assembly lube during engine rebuilds to prevent dry starts. Together, these complementary products provide maximum heavy-duty engine protection and performance.
