Schaeffer's SynShield Ultra Performance Diesel Engine Oil

Schaeffer's SynShield Ultra Performance diesel engine oil is a heavy-duty oil offering strong fuel economy benefits without sacrificing engine durability. Formulated to provide maximum protection against wear, oxidation, deposit formation, soot contamination, and aeration, this oil contains proprietary friction modifiers that create a slippery, tenacious shield, preventing metal-to-metal contact for increased engine efficiency. Schaeffer's SynShield Ultra Performance diesel engine 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). It 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 benefits: * Improved wear protection—85 percent less wear than conventional 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—77 percent greater soot handling than conventional 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 start-ability and low temperature pump-ability Show Less
