Listing for 1- 5 Gallon Bucket. Schaeffer’s 9000 SYNSHIELDT OTR PLUS SAE 5W-40 FULL SYNTHETIC ENGINE OIL. Exceeds API Service Categories for heavy-duty-diesel engine oil: CK-4, CJ-4, CI-4, CI-4 Plus and older. 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. Improved wear protection – 71% less wear than conventional 5W-40 CJ-4 oils. High thermal and oxidative stability for greater resistance to viscosity thickening and the formation of deposits, sludge and varnish. Excellent shear stability for stay-in-grade performance throughout the oil drain interval. Superior low volatility characteristics to control oil consumption. Improved and optimized engine durability and reliability – especially for older model engines. Excellent protection against oil aeration and foaming. Excellent cold crank startability and low temperature pumpability. Mobil 1 Amsoil Lucas Shell Rotella T6 Liqui Moly Motul.
