Our intelligent blending facility spans over 131 acres, achieving an annual production capacity of 200,000 tons. Equipped with automatic high-precision metering systems and advanced packaging machinery, the factory ensures a filling accuracy of 1‰ - 2‰. This advanced automation increases filling speeds by 20% to 35% compared to conventional operations, establishing a reliable supply chain that meets the rapid logistics and lead-time constraints of global distributors and OEM buyers.
The international motorcycle lubrication market is experiencing structural transformations. Rapid urbanization across Southeast Asia, Latin America, and Africa, combined with the explosive growth of last-mile delivery fleets globally, has positioned high-durability motorcycle engine oils (MCO) as critical operational assets. In these regions, motorcycles operate under severe stop-and-go patterns, high ambient temperatures, and overload conditions. Consequently, fleet managers and wholesale distributors require lubricants that do not just meet minimum standards, but dynamically resist viscosity shear, reduce oxidative thickening, and maintain stable clutch friction.
Operational Trend Shift: JASO MA2 vs. JASO MB
Modern motorcycles utilize common-sump configurations where the engine oil also lubricates the wet clutch and gearbox. Using standard passenger car motor oil (PCMO) in these applications leads to slippage of the wet clutch due to excessive friction modifiers. To address this, international procurement demands dictate strict compliance with the Japanese Automotive Standards Organization (JASO) T903 standard, separating products into JASO MA2 (high-friction performance for wet clutches) and JASO MB (low-friction formulations designed for automatic scooters).
Engine oil must execute multi-dimensional protection protocols. At Shandong Longhai Lubrication, our chemical engineers formulate engine oils utilizing high-grade base stocks (API Group II, Group III hydrocracked, and PAO synthetic alternatives) coupled with shear-stable viscosity index improvers (VII) and robust detergent-dispersant systems. This ensures that the lubricant maintains its structural integrity at high engine RPMs and operational temperatures.
| Lubricant Classification | Primary Viscosity Grades | Base Oil Chemistry | Frictional Performance (JASO) | API Quality Grade |
|---|---|---|---|---|
| Fully Synthetic Racing MCO | 5W-40, 10W-50 | PAO (Group IV) + Alkylated Naphthalene | MA2 (Optimized Clutch Grip) | API SP (LSPI Protection) |
| Premium Synthetic Technology | 10W-40, 15W-50 | Hydroisomerized (Group III) | MA2 (Balanced Wear Control) | API SN Plus |
| Heavy-Duty Fleet Scooter Oil | 10W-30, 20W-40 | Hydrotreated Mineral (Group II) | MB (Fuel Economy Focus) | API SL / SM |
| Extreme Climate Utility MCO | 20W-50 | Refined Mineral base | MA | API SJ |

Managing complex global distribution networks requires strict adherence to international shipping laws, safety compliance, and regional environmental standards.
Lubricants are classified under varying customs regulations worldwide. Our export department handles all safety documentation, including complete Safety Data Sheets (SDS) aligned with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). We offer custom packaging, moisture-barrier wrapping for sea transit, and logistics planning to prevent product degradation and delay at international ports of entry.
To provide peace of mind to our distributors and brand partners, our entire product catalog is insured under the PICC quality liability program. This comprehensive commercial guarantee protects against manufacturing deviations, ensuring that every batch of motor oil delivered to your local warehouse matches our technical data specifications.

For commercial procurement agents, oil distributors, and fleet managers, selecting a manufacturing partner requires balancing cost-efficiency with performance specifications. Our technical matrix provides a baseline for evaluating lubricating oil formulas:
| Technical Parameter | Required Minimum Spec | Significance in Operation | Longhai Quality Target |
|---|---|---|---|
| Kinematic Viscosity @ 100°C | 12.5 to 16.3 mm²/s (SAE 40) | Maintains hydrodynamic lubrication film under extreme heat. | Within ±0.2 mm²/s tolerance |
| Viscosity Index (VI) | Min 140 (Semi-Synthetic) | Resists viscosity thinning as the operating temperature rises. | 155+ (Highly stable Group III blends) |
| Total Base Number (TBN) | Min 7.0 mg KOH/g | Neutralizes corrosive combustion acids, preventing engine wear. | 8.5+ (Extended Drain Interval capacity) |
| Noack Volatility | Max 13.0% loss | Limits oil consumption and evaporation at high RPMs. | <10.5% (Low oil consumption) |
| High-Temperature High-Shear (HTHS) | Min 2.9 cP @ 150°C | Protects cylinder liners and bearings from wear under heavy load. | 3.5 cP (Superior engine wear prevention) |
As global emission regulations tighten (e.g., Euro 5, Euro 6, and Bharat Stage VI), motorcycle manufacturers are building tighter engine tolerances and adding complex catalytic converters. This transition requires lubricants to contain lower levels of Sulfated Ash, Phosphorus, and Sulfur (Low SAPS formulations).
Shandong Longhai's joint innovation center is researching next-generation friction modifiers that reduce internal drag without causing wet-clutch slippage. By using eco-friendly base stocks and biodegradable ester components, we aim to lower carbon footprints while maintaining high wear protection and engine cleanliness.
Our factory is located in Shandong, near Qingdao Port, allowing us to leverage direct maritime logistics channels to Europe, South America, Africa, and Southeast Asia.
To protect against shipping delays, custom holds, and damage, our cargo is packed in reinforced containers, palletized, and wrapped in water-resistant protective film. With PICC insurance covering our products, global buyers can confidently scale their importing operations, secure in the knowledge that they are backed by a certified Chinese lubricant manufacturer.
