Schaeffer Oil Synshield Otr Plus Full Synthetic 5W-40 Oil - 1 Quart

Schaeffer Oil SynShield® OTR Plus 5W-40 Engine Oil is a premium, fully synthetic heavy-duty diesel engine oil expertly formulated to provide maximum protection against wear, oxidation, deposit formation, soot contamination, and aeration. This advanced performance oil exceeds API Service Categories for heavy-duty diesel engine oil, including CK-4, CJ-4, CI-4, CI-4 Plus, and older specifications.

Designed to enhance fuel economy without compromising engine durability, SynShield® OTR Plus 5W-40 Engine Oil employs proprietary friction modifiers, Micron Moly® and Penetro®, to create a slippery, tenacious barrier that prevents metal-to-metal contact. This unique formulation increases engine efficiency, ensuring optimal performance even under the most demanding conditions.

This fully synthetic 5W-40 oil is suitable for use in emission-compliant engines that utilize 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). SynShield® OTR Plus 5W-40 Engine Oil is also compatible with low-emission certified diesel engines equipped with EGR, older non-EGR diesel engines, and off-highway diesel engines.
