SynShield® MBX-300 15W-40 is a high-performance, petroleum-based, heavy-duty diesel engine oil formulated to protect against wear, deposit formation and soot contamination.
Exceeds API Service Categories CK-4, CJ-4, CI-4, CI-4 Plus and older.SynShield® MBX-300 15W-40 provides dependable equipment durability and
longevity even during harsh, extreme duty operating conditions. Using our
proprietary friction modifiers, Micron Moly® and Penetro®, SynShield® MBX-300
15W-40 creates a slippery, tenacious shield that prevents metal-to-metal contact.
This added layer of durability protection significantly reduces wear on bearings,
rings, pistons, cylinders and valve trains.
It’s 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.
SynShield® MBX-300 15W-40 is an ideal choice for equipment owners who want
Schaeffer’s reliable protection but don’t need extended drains for their engines.
