Schaeffers Supreme 7000 Synthetic Plus Diesel Engine Oil 10W-30 12 Quarts with Wix Racing Filter

Exceeds API Service Categories for heavy-duty-diesel engine oil: CK-4, CJ-4, CI-4, CI-4 Plus and older.
SynShield™ OTR Plus is a premium advanced performance, synthetic plus, heavy-duty diesel engine oil formulated to provide maximum protection against wear, oxidation, deposit formation, soot contamination and aeration.

SynShield™ OTR Plus provides excellent fuel economy while maintaining engine durability and longevity. Using our proprietary friction modifiers, Micron Moly® and Penetro®,
SynShield™ OTR Plus creates a slippery, tenacious shield that prevents metal-to-metal contact for increased engine efficiency.
SynShield™ OTR Plus is suitable for use in 2007 and 2010 emission complaint 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 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 – 71% less wear than conventional 10W-30 CJ-4 oils.

Strong soot-busting, deposit-dispersing capability – 46% greater soot handling than conventional 10W-30 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.
