Engineered to deliver exceptional thermal stability, shear resistance, and anti-wear protection across industrial and automotive drivetrains.
Continuously Variable Transmissions (CVTs) represent a key technology in the automotive industry's pursuit of enhanced fuel economy and minimized greenhouse gas emissions. Unlike traditional stepped transmissions, a CVT relies on a steel push-belt or chain running between two variable-diameter pulleys to transfer torque. This mechanism permits an infinite number of gear ratios, enabling the internal combustion engine to operate at its peak thermal efficiency curve.
However, the mechanics of a CVT place extreme stress on the fluid medium. The interface between the steel pulleys and the metallic belt or chain operates under high-pressure, boundary-lubrication conditions. The CVT gearbox oil serves not merely as a lubricant, but as a critical dynamic element that must provide:
Note on Market Dynamics: The demand for premium synthetic CVT fluids is rising fast in the Asia-Pacific region, driven by the popularity of fuel-efficient passenger cars and the expansion of key suppliers in China.
The global lubricants market is shifting from Group I and Group II mineral oil bases toward advanced Group III hydrocracked and Group IV Polyalphaolefin (PAO) synthetic bases. Modern CVT fluid architectures demand low-viscosity designs to minimize parasitic drag while keeping the oil film thick enough under shear stress to prevent wear.
Recent innovations in CVT formulation concentrate on additive systems. Specifically, anti-wear agents, shear-stable viscosity index modifiers, and customized friction modifiers work in tandem to extend transmission service life. As vehicle drivetrains become more compact and generate higher torque density, standard oils fail to meet the required performance benchmarks. Leading automotive developers now require fluids that provide dual-action friction properties: high steel-on-steel friction combined with low paper-on-steel friction for the internal lock-up wet clutch.
High-shear rates in the pump and pulley contacts degrade low-quality viscosity index modifiers, causing the fluid to thin out at high operating temperatures. This loss of viscosity can lead to drop-offs in line pressure, pulley slippage, and eventual mechanical failure. Advanced synthetic CVT formulations leverage high-shear-stability polymers that retain their structure even when subjected to intense, continuous shearing forces.

Addressing technical challenges in modern continuously variable transmission fluids under real-world operating extremes.
In cold climates like Northern Europe, Canada, and Northern China, transmission fluids face high startup viscosity, which can lead to oil starvation, cavitation in the hydraulic pump, and belt slippage. To address this, our formulations are optimized to keep Brookfield viscosity at -40°C under 12,000 mPa·s. Conversely, in hot climates like the Middle East, high thermal load accelerates oil oxidation and causes thermal shearing. Longhai's synthetic base oils prevent thermal breakdown and preserve structural integrity up to continuous running temperatures of 150°C.
Frequent start-stop cycles in city driving heat up the wet startup clutch, causing wear and shuddering. To prevent this, our additives include friction modifiers that maintain consistent boundary lubrication. The fluid suppresses shudder and dampens vibrations, protecting the belt and pulley systems during low-speed high-torque shifts.
CVT mechanics are increasingly deployed in agricultural equipment, construction machinery, and specialized industrial drives. These heavy duties require fluids that can handle sustained load carrying without foaming. By incorporating silicone-free anti-foam agents, our lubricants prevent air entrapment, maintaining continuous pressure across hydraulic control valves.
Technical explanations regarding CVT fluid performance, compatibility, and industrial specifications.
Traditional Automatic Transmission Fluid (ATF) is formulated to lubricate gears and wet multi-plate clutches, requiring low steel-on-steel friction to facilitate smooth shifts. In contrast, CVT fluid needs a high coefficient of steel-on-steel friction to prevent the metal belt or chain from slipping against the smooth steel pulleys under high clamping pressure. Using standard ATF in a CVT will lead to belt slippage, heat buildup, and transmission failure.
We formulate our fluids using Group III synthetic base oils combined with shear-stable star polymer viscosity index modifiers. Under high shear, these molecules compress without breaking, then expand back to their original state once the stress is relieved. This maintains consistent viscosity and hydraulic control pressure across extended service intervals.
Yes. Our premium synthetic CVT fluid line is engineered as a multi-vehicle fluid that covers older generation specifications (such as Nissan NS-2, Toyota TC) as well as modern, lower-viscosity standards (Nissan NS-3, Toyota FE, Honda HCF-2). It is compatible with both belt-driven and chain-driven CVT systems.
While some vehicle manufacturers suggest "fill-for-life" fluids, real-world testing shows that replacing CVT fluid every 60,000 to 80,000 kilometers protects components against wear from accumulated micro-metals and maintains optimal torque transmission efficiency.
