Description

SCHAEFFER’S (since 1839) – 700 SynShield® Durability Advantage Engine Oil 15W-40 is a premium, advanced performance, synthetic plus heavy-duty diesel engine oil designed to provide exceptional protection and durability for diesel engines in the most extreme operating conditions. Formulated with a blend of advanced additives and proprietary friction modifiers such as Micron Moly® and Penetro®, this oil creates a slippery, tenacious shield that reduces wear on critical engine components like bearings, rings, pistons, cylinders, and valve trains, helping to ensure long-lasting engine performance.

SynShield® Durability Advantage 15W-40 exceeds API service categories including CK-4, CJ-4, CI-4, CI-4 Plus, and older specifications, providing superior wear protection, improved thermal and oxidative stability, and enhanced resistance to soot contamination, oxidation, and deposit formation. With 85% less wear compared to conventional CJ-4 oils, it helps minimize engine downtime and ensures that your diesel engine performs optimally even under severe duty conditions.

This high-performance oil is compatible with emission-compliant diesel engines equipped with heavy exhaust gas recirculation (EGR) systems, diesel particulate filters (DPFs), diesel oxidation catalysts (DOCs), and selective catalytic reduction (SCR) systems. Additionally, it is suitable for use in older, non-EGR diesel engines and off-highway diesel engines. SynShield® Durability Advantage 15W-40 offers superior protection against oil aeration and foaming, ensuring consistent lubrication under demanding conditions and reducing the risk of equipment failure.

Distributed worldwide by Miken Electronics, this oil delivers long-term engine reliability and performance, helping to optimize the lifespan and efficiency of your diesel engine.
