In the global logistics sector, manual transmission (MT) durability is paramount. Our manual gearbox oils are engineered to extend drain intervals and reduce friction in heavy-duty long-haul trucks, directly impacting the Total Cost of Ownership (TCO) for fleet operators.
Beyond automotive, precision manual gearboxes in manufacturing plants require high-stability lubricants. We provide formulations that withstand high torque and extreme temperature fluctuations, ensuring 24/7 operational continuity for industrial machinery.
From the freezing temperatures of Northern Europe to the scorching heat of the Middle East, our oils maintain optimal viscosity indices. We specialize in GL-4 and GL-5 grade products that protect synchronizers and gears against pitting and oxidation.
Shandong Longhai Lubrication Technology Development Co., Ltd. (established in 2009) represents the pinnacle of Chinese lubricant R&D. Our facility in Zibo, Shandong, spans 131 acres with an annual capacity of 200,000 tons.
By investing 5% of annual revenue into R&D, we ensure our manual gearbox oils provide an information gain to our clients—offering not just oil, but a scientifically proven friction-reduction roadmap.
In regions like South America and Australia, manual gearboxes in mining trucks face extreme loads. Our oil features high-load-carrying additives that prevent metal-to-metal contact even under peak stress.
Tractors and harvesters require lubricants that are compatible with yellow metals (copper, bronze). Our MTF formulations are non-corrosive to synchronizer rings, extending the life of agricultural hardware.
We provide full documentation for international customs, including SDS (Safety Data Sheets), REACH compliance for Europe, and localized labeling to meet the regulatory demands of 29+ provinces and global markets.
