Schaeffer Oil Synshield Durability Advantage 15W-40 Engine Oil - 1 Quart

Schaeffer Oil SynShield® Durability Advantage 15W-40 Engine Oil is a premium, advanced performance synthetic plus heavy-duty diesel engine oil engineered to provide maximum protection against wear, oxidation, deposit formation, soot contamination, and aeration. Exceeding API Service Categories for heavy-duty diesel engine oils, including CK-4, CJ-4, CI-4, CI-4 Plus, and older specifications, this oil is designed for the rigorous demands of modern diesel engines.

SynShield® Durability Advantage 15W-40 enhances equipment durability and longevity, even in harsh, extreme operating conditions. Featuring proprietary friction modifiers, including Micron Moly® and Penetro®, this engine oil forms a slippery, tenacious shield that effectively prevents metal-to-metal contact. This added layer of protection significantly reduces wear on critical components, such as bearings, rings, pistons, cylinders, and valve trains.

This versatile 15W-40 oil is suitable for use in emission-compliant engines utilizing heavy exhaust gas recirculation (EGR) and exhaust after-treatment devices, including diesel particulate filters (DPFs) with or without diesel oxidation catalysts (DOCs) and selective catalytic reduction (SCR). Additionally, SynShield® Durability Advantage 15W-40 is compatible with low-emission certified diesel engines equipped with EGR, older non-EGR diesel engines, and off-highway diesel applications.

Performance Benefits:

• Enhanced Wear Protection: Provides 85% less wear than conventional CJ-4 oils, extending engine life.
• Thermal and Oxidative Stability: High stability resists viscosity thickening and the formation of deposits, sludge, and varnish.
• Superior Soot Handling: Offers 77% greater soot dispersion compared to conventional CJ-4 oils, ensuring cleaner engine operation.
• Excellent Shear Stability: Maintains stay-in-grade performance throughout the oil drain interval for consistent lubrication.
• Low Volatility Characteristics: Controls oil consumption effectively, ensuring optimal performance.
• Improved Engine Durability: Enhances reliability during high mileage and hour accumulation scenarios.
• Protection Against Aeration: Provides excellent resistance to oil aeration and foaming, maintaining oil integrity under pressure.

Schaeffer Oil’s SynShield® Durability Advantage 15W-40 Engine Oil is the optimal choice for operators seeking superior protection and performance in their diesel engines, ensuring reliable operation and extended service life in demanding conditions.
