SynShield® OTR Plus 5W-40 Engine Oil is a premium advanced performance, fully synthetic, heavy-duty diesel engine oil formulated to provide maximum protection against wear, oxidation, deposit formation, soot contamination and aeration.

SynShield® OTR Plus 5W-40 Full Synthetic Engine Oil provides excellent fuel economy while maintaining engine durability and longevity. Using our proprietary friction modifiers, Micron Moly® and Penetro®, SynShield® OTR Plus 5W-40 Engine Oil creates a slippery, tenacious shield that prevents metal-to-metal contact for increased engine efficiency.

Our fully synthetic 5W-40 oil is suitable for use in 2007 and 2010 emission compliant engines that utilize heavy exhaust gas recirculation (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® OTR Plus 5W-40 Full Synthetic Oil can also be used in low-emission certified diesel engines that are equipped with EGR, older non-EGR containing diesel engines, and off-highway diesel engines.
