Listing for 1 Gallon Schaeffer's Full Synthetic 5W-40 Diesel 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 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.Performance BenefitsImproved 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.Strong soot-busting, deposit-dispersing capability – 46% greater soot handling than conventional 5W-40 CJ-4 oils.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.
