*Up to 5% fuel economy improvement!
You put serious miles on your engine. You need oil that can keep up — and keep your engine protected when you're fully loaded, running hot, or firing up in the cold at 4am.
Schaeffer's 9000 SynShield® OTR Plus is built on the same high-performance additive technology as the proven SynShield® Durability Advantage 15W-40 — now in a full synthetic 5W-40 formulation optimized for modern diesel engines and OTR applications.
At the core of OTR Plus are two proprietary frictional modifier technologies: Micron Moly®, a liquid-soluble molybdenum compound, and Penetro™, Schaeffer's own additive. Together they form a persistent boundary film that eliminates metal-to-metal contact across all engine operating conditions.
*71% less wear vs. conventional CJ-4 oils
*46% greater soot-handling capacity vs. conventional CJ-4
*Up to 5% fuel economy improvement
*Extended drain intervals — reduced oil consumption and service cost
*Excellent cold-crank and pumpability performance at low temperatures
*Strong oxidative stability and thermal degradation resistance
*High viscosity index — stable performance across operating temperature range
