Description

SCHAEFFER’S (Since 1839) 9012 SynShield® OTR Plus Full Synthetic 10W-30 is a premium, full synthetic heavy-duty diesel engine oil engineered to offer significant fuel economy benefits without sacrificing engine durability. This advanced performance oil is formulated to provide maximum protection against wear, oxidation, soot contamination, deposit formation, and aeration, ensuring the longevity and reliability of your engine.

SynShield® OTR Plus 10W-30 exceeds the API Service Categories for heavy-duty diesel engine oils, including CK-4, CJ-4, CI-4, CI-4 Plus, and older engine models. It is specially designed to deliver excellent fuel efficiency while maintaining exceptional engine durability through the use of Schaeffer’s proprietary friction modifiers, Micron Moly® and Penetro®. These additives form a tenacious, slippery shield that reduces metal-to-metal contact, optimizing engine performance and reducing friction.

This fully synthetic oil is suitable for emission-compliant engines equipped with advanced exhaust gas recirculation (EGR) systems, as well as after-treatment devices such as diesel particulate filters (DPFs), diesel oxidation catalysts (DOCs), and selective catalytic reduction (SCR). Additionally, it can be used in low-emission certified diesel engines, older non-EGR diesel engines, and off-highway diesel engines.

SynShield® OTR Plus 10W-30 offers improved wear protection, reducing wear by 71% compared to conventional 10W-30 CJ-4 oils. With high thermal and oxidative stability, it resists viscosity thickening and the formation of deposits, sludge, and varnish, ensuring smooth engine operation. The oil also excels in soot handling and deposit dispersion, offering 46% better soot management than conventional oils. SynShield® OTR Plus 10W-30 maintains excellent shear stability, superior low volatility characteristics to minimize oil consumption, and enhanced engine durability, making it ideal for both modern and older diesel engines.
