Continuously Variable Transmissions (CVTs) have redefined automotive efficiency. Unlike traditional step-automatic transmissions that rely on planetary gear sets, CVTs transfer torque via a metal belt or chain running between two variable-diameter pulleys. This continuous contact places extreme tribological demands on the lubricant.
The best CVT gearbox oil must balance two seemingly contradictory requirements: high metal-on-metal friction to prevent belt/chain slippage, and excellent anti-wear properties to protect the complex hydraulic pump and control valves. As a leading CVT manufacturer and supplier, Shandong Longhai Lubrication Technology understands these microscopic stresses and develops formulations that ensure sustained power transfer efficiency and components longevity.
Modern high-torque engines require CVT fluids that maintain viscosity under extreme shear stress. Low-quality oils degrade rapidly, resulting in catastrophic belt slip.
Global buyers prioritize extended drain intervals. Fluid longevity directly translates to lower operational costs for fleet operators and less maintenance for consumers.
Cold climates require excellent low-temperature fluid dynamics. Rapid circulation during cold starts prevents premature wear on pulleys and belts.
Shandong Longhai Lubrication Technology represents the pinnacle of Chinese Factory 4.0 manufacturing. Occupying a modern production facility of 131 acres, the company leverages cutting-edge automated blending techniques that ensure batch-to-batch consistency.
The implementation of high-precision flow control systems guarantees an oil filling accuracy of 1‰-2‰. Furthermore, our fully automated packaging lines have boosted throughput by 20%-35%, allowing us to respond swiftly to sudden fluctuations in global market demand without sacrificing quality control.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating research and development, production, and sales. For over 15 years, we have been deeply involved in the lubricant industry, constructing a robust and complete industrial chain system.
Longhai Technology proudly owns the domestic brand "Century Longhai" alongside our international strategic partnership brand, the British "A Ba" series. Our product catalog spans passenger car motor oils, heavy-duty diesel engine oils, industrial gear oils, hydraulic transmission fluids, and special agricultural machinery oils. Our brand is fully backed by product quality insurance from the People's Insurance Company of China (PICC), giving our global clients unmatched peace of mind.
Quality is our lifeline. We strictly adhere to international management systems to ensure that our CVT fluids and motor lubricants perform exceptionally even under extreme conditions.
Our production processes are certified under ISO 9001:2015, ISO 14001 environmental, and ISO 18001 occupational health management systems. In addition, our automatic transmission products have received official Mercedes-Benz approvals, ensuring top-tier reliability.
Frequent acceleration and deceleration in dense traffic build intense heat within the CVT casing. Our premium formulation prevents thermal breakdown and ensures smooth ratio changes without judder.
In colder regions like Northern Europe or North America, fluid viscosity must remain low enough at start-up to lubricate the hydraulic controls instantly. Our high-VI synthetic base oils guarantee cold-start defense.
Vehicles transporting heavy passenger loads require enhanced steel-on-steel friction coefficient stability. Our additives prevent pulley wear and belt slippage under constant high load demands.
Our annual R&D investment exceeds 5% of our revenue. We have partnered with top-tier technical institutes and additives suppliers to offer customizable lubricant options:
Evaluating OEM specs and regional climatic demands.
Selecting base oils and balancing friction modifiers.
Simulating shear stress and friction coefficient limits.
Automated blending, packing, and ISO-checked logistics.
On-site testing feedback and marketing support.
CVT fluids are engineered to have high steel-on-steel friction characteristics to prevent the drive belt or chain from slipping on the smooth metal pulleys. Standard ATF, on the other hand, is optimized for shifting clutches and planetary gears. Using standard ATF in a CVT will lead to belt slippage, heat buildup, and eventual transmission failure.
Yes, our R&D laboratory can adjust additive packages to achieve compliance with specific OEM guidelines such as Nissan NS-3, Toyota FE, Honda HCF-2, and others. We modify dynamic friction characteristics and low-temperature viscosities according to target market needs.
All our export products are blended with premium, shear-stable synthetic base oils and packed in airtight, corrosion-proof packaging. We conduct thermal stress tests on every batch to ensure that humidity and ambient temperature fluctuations during sea transit do not compromise the fluid's chemistry.
MOQ varies based on the packaging size (e.g., 1L, 4L, or 200L drums). Typically, for customized private labels, we require a minimum volume equivalent to one 20-foot container to optimize raw materials and production line cleaning cycles.
