Explore our premium grade heavy-duty lubricants, refrigeration systems protection agents, and high-performance synthetic engine oils engineered for extreme operational demands.
The global transportation and industrial machinery landscapes are undergoing an unprecedented technological revolution. As high-speed logistics networks expand and engines become more compact, power densities have spiked. Standard mineral-based oils struggle to cope with the extreme thermal stresses, mechanical shear, and oxidation rates seen in modern systems. In response, advanced fully synthetic motor oils have moved from niche performance upgrades to standard industrial requirements.
This macro shift is driven by strict global emission regulations (such as Euro VI, Stage V, and China VI standards) and a industry-wide mandate to maximize operational uptime. Shandong Longhai Lubrication Technology is at the forefront of this movement, engineering high-viscosity index lubricants that retain their molecular structure at sustained high temperatures while ensuring seamless flowability in sub-zero environments.

The molecular engineering behind low viscosity, high-temperature stability, and clutch friction optimization.
Compared to automotive engines, motorcycle engines run at much higher RPMs, higher power-to-displacement ratios, and higher operating temperatures. In addition, a single oil reservoir is often shared by the engine, the gearbox, and the wet clutch. This means the oil has to perform three critical, yet contrasting, jobs: protecting the engine from wear, ensuring smooth gear changes, and preventing clutch slippage.
| Lubricant Property | Mineral Base Oil | Semi-Synthetic Oil | Fully Synthetic (PAO/Ester) | Impact on Moto Performance |
|---|---|---|---|---|
| Viscosity Index (VI) | 90 - 100 | 115 - 135 | 150 - 185+ | Ensures consistent film thickness across extreme hot and cold temperatures. |
| High-Temp Shear Stability | Poor | Moderate | Excellent (Low SSI polymers) | Protects high-stress areas like cams and gears from direct metal-on-metal contact. |
| Clutch Friction Coefficient | Low (risk of slip) | Medium (meets JASO MA) | High & Balanced (JASO MA2) | Prevents clutch slippage under high torque, ensuring maximum power delivery. |
| Oxidation Resistance | Baseline | Improved | Ultra-High | Extends oil life and prevents varnish formation in high-heat engines. |
Our synthetic formulations use a blend of synthetic base oils mixed with high-performance friction modifiers that meet the JASO MA2 specification. By controlling the formulation's physical properties, we prevent clutch slippage and wear on high-load gear components. This keeps motorcycle engines running smoothly, preserves gear teeth, and improves overall power transmission.
From initial design to global market compliance, we build tailored lubricant brands for partners worldwide.
We develop fully synthetic and semi-synthetic lubricant recipes tailored to specific vehicle and equipment needs, local climates, and targeted API/ACEA performance ratings.
Our production lines support everything from small-scale testing batches to high-volume commercial runs, covering engine oils, gear oils, and specialty industrial fluids.
All batches undergo strict testing. We work with accredited third-party laboratories to provide comprehensive compliance certificates and safety data sheets (SDS).
We provide full branding support, including customized packaging design, anti-counterfeiting labels, and technical documentation to streamline your market entry.

How Longhai designs specialized lubricants to tackle extreme environmental and local regulatory challenges.
Transporting goods through sub-zero climates requires lubricants with low-temperature fluidity. Our synthetic heavy-duty diesel engine oils, formulated with premium polyalphaolefins, have a pour point of -45°C. This allows fleet operators to start their engines easily in extreme cold, minimizing wear during startup and lowering starter battery strain.
Heavy industrial equipment operating in desert environments faces high temperatures and airborne dust. Longhai's high-viscosity anti-wear hydraulic fluids and industrial gear oils are formulated with thermal stabilizers. These additives prevent oxidation and oil shearing, keeping hydraulic pressure stable and protecting gear components from abrasive wear.
With the rapid growth of last-mile delivery services in hot, humid regions, motorcycles face prolonged stop-and-go driving conditions. Our JASO MA2 motorcycle oils are engineered to handle these intense duty cycles, managing heat buildup to prevent clutch slippage and protect components over extended service intervals.
For regions requiring low-SAPS (Sulfated Ash, Phosphorus, and Sulfur) formulations, our CK-4 diesel oils are designed to protect modern exhaust after-treatment systems, including Diesel Particulate Filters (DPFs) and Selective Catalytic Reduction (SCR) systems, ensuring full compliance with emission standards.
Developing next-generation solutions, with a focus on bio-degradable base stocks, ultra-low viscosity fluids, and EV compatibility.
The lubrication industry is adapting to support cleaner, more efficient energy systems. Longhai Technology's R&D roadmap is focused on three major development areas:

Expert answers to common questions about synthetic oils, formulations, and machinery protection.
Fully synthetic motorcycle oils, formulated with PAO and synthetic esters, offer much higher thermal and oxidation stability compared to mineral oils. They maintain their viscosity at high temperatures, reduce evaporation losses, and prevent varnish buildup. They also provide superior fluid flow in cold weather, minimizing startup wear and ensuring smooth wet-clutch operation and gear protection.
JASO MA2 is a Japanese standard that specifies high-friction performance for wet clutches. Unlike passenger cars, most 4-stroke motorcycles share the same oil between the engine, gearbox, and clutch. JASO MA2 oils are formulated to prevent clutch slippage under high loads, ensuring efficient power transfer and smooth gear shifts.
