Deep Technical Insights into Base Oils, Shear Stability, and Wet-Clutch Performance
Unlike standard Passenger Car Motor Oils (PCMO), premium mineral motorcycle oils are engineered to address the unique tribological demands of integrated engine-gearbox systems. In a typical motorcycle, the lubricant must simultaneously protect the piston assembly, cushion the gear transmission, and provide the exact coefficient of friction required by the wet clutch system.
Shandong Longhai's mineral oil formulations rely on highly refined Group II base stocks. By utilizing advanced hydrocracking processes, we eliminate sulfur, nitrogen, and aromatic impurities. This yields a base oil with exceptional thermal-oxidative stability, preventing viscosity breakdown under the extreme shear environments of high-RPM motorcycle engines.
Our motorcycle lubricants are rigorously tested to comply with the Japanese Automotive Standards Organization (JASO) T 903 standard. Specifically, for motorcycles equipped with wet clutches, our formulations are optimized to meet JASO MA2 requirements, delivering high static and dynamic friction parameters to prevent clutch slippage under maximum load.
Shandong Longhai Lubrication Technology Development Co., Ltd., established in 2009, operates a state-of-the-art 131-acre manufacturing and blending base in Zibo, Shandong. This strategic hub produces up to 200,000 tons of lubricants annually, making us one of China's most robust export-oriented lubricant suppliers.
Our blending facility leverages fully automated metering and filling lines. This design guarantees a filling accuracy of 1‰-2‰ while boosting packaging speed by 20% to 35% compared to conventional operations. By reducing human error and improving precision, we maintain consistent formulation chemistry from batch to batch. This structural scale allows us to offer global distributors highly competitive pricing without compromising on material inputs.
In the contemporary B2B landscape, procurement officers look beyond basic API and ACEA ratings. Today's global supply chain demands compliance, tracking, and consistency. Procurement managers face the challenge of securing oils that withstand highly fluctuating localized ambient temperatures—from the tropical zones of Southeast Asia to the arid climates of the Middle East.
To meet these needs, Shandong Longhai offers multi-viscosity mineral blends (such as 10W-40, 15W-50, and 20W-50) using premium shear-stable viscosity index improvers (VII). These additive packages maintain the structural integrity of the oil film even at localized cylinder temperatures exceeding 150°C, ensuring that fleet operations, logistics services, and motorcycle rental enterprises minimize mechanical failures.
Our operational capabilities translate to performance-backed solutions for global industrial and transport fields.
We reinvest over 5% of our annual revenue into proprietary laboratory research and joint development programs with leading scientific institutions to refine our formula matrices.
Certified by ISO 9001:2015, ISO 14001, and ISO 45001. We maintain automatic transmission fluid certifications from Mercedes-Benz, validating our quality consistency.

Mineral oils are heavily valued in commercial distribution networks, last-mile delivery services, and extreme environments where oil drain intervals are short due to high dust and particulate contamination. In regions such as Africa, Latin America, and South Asia, commercial motorcycle fleets operate under heavy payloads and stop-and-go conditions. Under these conditions, the engine oil must control soot accumulation and resist oxidation.
Longhai's Mineral Motorcycle Oils are infused with high-performance detergent-dispersant additive systems. These chemical packages hold combustion byproducts in suspension, preventing the formation of varnish on piston skirts and sludge in the oil sump. As a result, critical engine components remain clean, and lubricant pathways stay unobstructed, reducing downtime for commercial logistics fleets.
Exporting lubricants globally involves navigating a complex web of environmental and customs regulations. Every product shipped by Shandong Longhai comes with complete technical documentation, including safety data sheets conforming to GHS standards, and meets the import criteria of destination ports worldwide. Our close partnership with major shipping hubs in Qingdao and Tianjin guarantees timely dispatch, competitive ocean freight rates, and smooth customs clearance procedures.
