• Better contamination control with superior soot-busting, deposit-dispersing capability.
• Strong stay-in-grade performance throughout the life of the oil.
• Friction modified with Micron Moly® and Penetro® to provide strong protection against wear, scuffing and abrasion.
• Improved and optimized engine durability and reliability during high mileage, hour accumulation situations.
• Meets Ford spec WSS-M2C171-F1.

SynShield™ Durability Advantage SAE 15W-40 is a premium advanced performance, synthetic plus, heavy-duty diesel engine oil specially formulated to provide excellent equipment durability and longevity even during harsh, extreme duty operating conditions. SynShield™ Durability Advantage SAE 15W-40 exceeds the requirements for API heavy-duty diesel engine oil Service Categories: CK-4, CJ-4, CI-4, CI-4 Plus and older. The product is particularly suitable for use in emission compliant engines that utilize heavy EGR and exhaust after-treatment devices such as Diesel Particulate Filters (DPFs) with or without Diesel Oxidation Catalysts (DOCs) and Selective Catalytic Reduction (SCR). SynShield™ Durability Advantage SAE 15W-40 provides advanced performance in low- emission certified diesel engines that are equipped with EGR, older non-EGR containing diesel engines, and off-highway diesel engines. SynShield™ Durability Advantage SAE 15W-40 provides the following performance advantages:

PERFORMANCE o Maximum engine protection during high mileage/hour accumulation, extended drains and severe idling time for maximized uptime and reliability o Improved fuel economy benefits and excellent fuel economy retention o Excellent cold cranking startability and low temperature pumpability to ensure the engine oil reaches critical engine parts faster in colder temperatures in order to minimize wear o Superior low volatility characteristics to control oil consumption o Excellent protection against oil aeration and foaming o Prolonged gasket, seal life, and after-treatment (DPF and DOC) life o Longer drain intervals for lower overall maintenance costs o Increased engine life and durability especially for older model engines

DEPOSIT PROTECTION o Enhanced detergency and dispersency to provide high temperature piston cleanliness o Superior protection against deposits – 77% greater soot-handling than conventional CJ-4 oils o Superior thermal and oxidative stability resulting in a greater resistance to viscosity thickening and the formation of deposits, sludge and varnish on critical engine parts. o Superior engine cleanliness for longer filter life and protection against filter plugging

WEAR PROTECTION o Superior wear protection– 85% less wear than conventional CJ-4 oils o Exceptional ring and liner wear protection that results in improved oil consumption control o Superior resistance to corrosive and abrasive wear o Exceptional valve-train wear protection o Excellent protection against oxidation and corrosion in the presence of biodiesel

SynShield™ Durability Advantage SAE 15W-40 also contains two proven frictional modifiers Micron Moly® and Schaeffer Mfg’s own proprietary additive Penetro®. These two proven frictional modifiers once plated, form a long lasting, slippery, tenacious lubricant film, which prevents the metal surfaces from coming into contact with each other. By preventing metal-to-metal contact, damaging frictional wear is reduced which results in reduced wear, increased engine life and lower maintenance costs.
