Description

SCHAEFFER’S (Since 1839) 723 SynShield® Ultra Performance Full Synthetic 5W-30 Engine Oil is a high-performance, fully synthetic, heavy-duty diesel engine oil designed to provide superior protection for your engine while maintaining excellent fuel economy. Formulated with advanced additives and synthetic base oils, this oil delivers maximum protection against wear, oxidation, deposit formation, soot contamination, and aeration, ensuring reliable and efficient engine performance in a variety of conditions.

Exceeding API Service Categories CK-4, CJ-4, CI-4, CI-4 Plus, and older, SynShield® Ultra Performance 5W-30 is engineered for both on-highway and off-highway applications. It is ideal for engines operating under severe stop-and-go driving, excessive idling, short haul, or severe duty conditions. The oil’s proprietary friction modifiers, Micron Moly® and Penetro®, create a slippery, tenacious shield on engine parts, reducing metal-to-metal contact and boosting overall engine durability and efficiency.

SynShield® Ultra Performance 5W-30 is fully compatible with emission-compliant engines that use exhaust gas recirculation (EGR) systems and after-treatment devices such as diesel particulate filters (DPFs), diesel oxidation catalysts (DOCs), and selective catalytic reduction (SCR). It is also suitable for use in low-emission certified diesel engines equipped with EGR, as well as older non-EGR diesel engines and off-highway diesel engines.

This full synthetic oil delivers 85% less wear than conventional CJ-4 oils, offering excellent protection against the buildup of harmful deposits, sludge, and varnish. Its exceptional soot-busting capabilities provide 77% better soot handling compared to conventional oils, while maintaining fuel economy and delivering superior shear stability for long oil drain intervals. The oil’s low volatility characteristics help control oil consumption, while its excellent cold crank startability and low-temperature pumpability ensure reliable engine starts in extreme conditions.
