SynShield® OTR Plus Full Synthetic Engine Oil 10W-30

Full synthetic heavy-duty diesel oil that offers strong fuel economy benefits without sacrificing engine durability.

SynShield® OTR Plus 10W-30 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.

Exceeds API Service Categories for heavy-duty-diesel engine oil: CK-4, CJ-4, CI-4, CI-4 Plus and older.

SynShield® OTR Plus 10W-30 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 10W-30 Engine Oil creates a slippery, tenacious shield that prevents metal-to-metal contact for increased engine efficiency.

Our fully synthetic 10W-30 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 10W-30 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 Benefits

• Improved wear protection – 71% less wear than conventional 10W-30 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 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.
