Beijing, China – Lubrizol, a global leader in specialty chemicals, has introduced a high-performance lubricant solution — Lubrizol® GO3426 fluid that is designed specifically for automated manual transmissions (AMTs) in heavy-duty trucks. Tailored to the unique operational needs of AMT systems, the solution is engineered to help improve fuel efficiency by lowering viscosity from 80W-90 to 75W-80, optimize shift performance① and support long-term durability② —ultimately contributing to the broader goals of smarter and more efficient commercial vehicle operation.

As China's heavy-duty truck sector embraces intelligent technologies and stricter emissions standards, AMTs are rapidly gaining ground as a preferred drivetrain option. Offering benefits such as reduced driver fatigue, improved fuel economy, and better integration with modern emissions systems, AMTs are increasingly replacing traditional manual transmissions-especially in long-haul and high-frequency urban delivery applications.

"The widespread adoption of AMTs reflects growing industry demand for vehicles that balance comfort, efficiency, and regulatory compliance," said Henry Liu, Vice President of Lubrizol Asia Pacific and Vice President of Lubrizol Additives APAC. "This shift places greater expectations on lubricant performance-not only to support efficient operation but to ensure consistency and reliability over time."

Lubrizol® GO3426 fluid is developed with advanced base oil selection and additive system design, offering balanced viscosity control and strong low-temperature pumpability ③. These properties help maintain transmission efficiency and reliable performance, even under demanding operating and environmental conditions.

The formulation has been validated across mainstream AMT applications that demand ODI (oil drain interval) beyond 200,000 km and up to 300,000 km，demonstrating strong protection against gear and synchronizer wear while improving friction response during shifting ④. It is engineered to meet the precise friction control needs of modern control mechanisms such as layshaft brakes (LSB). With excellent oxidative stability and seal compatibility, the lubricant supports extended drain intervals of over 300,000 kilometers-helping reduce maintenance frequency and total cost of ownership.

"Our goal is to provide technology that supports more efficient and dependable AMT performance," Henry added. "Lubrizol remains committed to working closely with OEMs, transmission manufacturers, and lubricant marketers to deliver practical, proven solutions that align with the evolving needs of the commercial transportation sector."
