Description

SCHAEFFER’S (Since 1839) 9000 SynShield® OTR Plus Full Synthetic 5W-40 is a premium, fully synthetic, heavy-duty diesel engine oil formulated to offer exceptional fuel economy benefits without compromising engine durability. Designed for the most demanding diesel applications, this advanced performance oil provides maximum protection against wear, oxidation, deposit formation, soot contamination, and aeration, ensuring long-lasting protection for your engine.

SynShield® OTR Plus 5W-40 Full Synthetic Engine Oil exceeds API Service Categories for heavy-duty diesel engine oils, including CK-4, CJ-4, CI-4, CI-4 Plus, and older engine models. It delivers superior fuel economy while maintaining engine durability and longevity through the use of Schaeffer’s proprietary friction modifiers, Micron Moly® and Penetro®. These additives create a slippery, tenacious shield that reduces metal-to-metal contact, boosting engine efficiency and performance.

This oil is specifically formulated for use in emission-compliant diesel engines equipped with advanced exhaust gas recirculation (EGR) systems and exhaust after-treatment devices such as diesel particulate filters (DPF), diesel oxidation catalysts (DOC), and selective catalytic reduction (SCR). It is also suitable for low-emission certified diesel engines, older non-EGR diesel engines, and off-highway diesel engines.

SynShield® OTR Plus 5W-40 provides improved wear protection, with 71% less wear compared to conventional 5W-40 CJ-4 oils. It has excellent thermal and oxidative stability to resist viscosity thickening and deposit formation, ensuring the engine runs smoothly even under extreme conditions. Additionally, it boasts superior soot handling and deposit-dispersing capabilities, optimized shear stability for consistent performance throughout the oil drain interval, and superior low volatility characteristics that control oil consumption.
