The WG9007300012 ZF Transmission Special Oil MTF C-I 85W-90 is a premium-grade lubricant engineered specifically for ZF transmissions in HOWO heavy-duty trucks, proudly offered within the Howo/Sitrak truck parts portfolio. This advanced oil delivers exceptional gear protection, smooth shifting performance, and extended transmission life under the most demanding operating conditions. With the WG9007300012, you achieve reduced friction, superior wear resistance, and optimal thermal stability. Its specially balanced formulation ensures reliable operation across a wide temperature range, making it the definitive choice for fleet operators seeking maximum drivetrain reliability.
Formulated with high-quality base oils and advanced additive technology, the WG9007300012 provides outstanding anti-wear protection, oxidation stability, and corrosion resistance. Its precise viscosity grade (85W-90) ensures consistent lubrication under extreme pressure and temperature, safeguarding critical transmission components and maximizing uptime.
The WG9007300012 is formulated with extreme-pressure (EP) additives that form a durable protective film on gear teeth and bearing surfaces. This significantly reduces wear, pitting, and scuffing, extending transmission life by up to 50%.
Independent testing confirms that the part exceeds ZF and API GL-5 performance requirements, providing exceptional protection against wear and fatigue in demanding heavy-duty applications.
Engineered with high-quality base oils and advanced oxidation inhibitors, the WG9007300012 resists thermal breakdown even at sustained high temperatures. This prevents sludge and varnish formation, keeping transmissions clean and efficient.
The WG9007300012 maintains its viscosity and lubricating properties over extended drain intervals, reducing maintenance costs and minimizing environmental impact.
The WG9007300012 is engineered to provide excellent synchromesh compatibility, ensuring smooth and precise gear engagement. Its optimized friction characteristics reduce shift effort and improve driver comfort.
The advanced formulation of the part enables extended oil change intervals of up to 80,000 kilometers, significantly reducing maintenance downtime and waste oil generation.
