Engineered to exceed JASO MA2, API SP, and high-temperature tribological load specifications.
The global two-wheeler sector is undergoing a massive transformation. Rapid urbanization in Southeast Asia, South Asia, and Latin America, coupled with the critical expansion of last-mile delivery services worldwide, has pushed motorcycle and scooter operations to their limits. Unlike passenger cars, two-wheeler engines operate under extreme conditions: higher thermal loads, higher RPM limits (often exceeding 10,000 RPM), and unified sump configurations where the engine, wet clutch, and gearbox share the same oil.
This demanding environment requires precision-engineered lubricants that prevent clutch slippage, offer superior shear stability, and withstand severe thermal breakdown. As one of China's premier heavy-duty and two-wheeler lubricant exponents, Shandong Longhai Lubrication Technology Development Co., Ltd. offers customized fluid engineering designed to optimize engine power density while complying with the most rigorous emission legislations.
Formulated with specialized friction modifiers that comply directly with the Japanese Automotive Standards Organization (JASO) T 903:2016 MA2 performance parameters.
Maintains viscosity even in high-stress gears, preventing metallic contact under severe load and boundary lubrication phases.
Reduces peak operating temperatures by up to 15°C compared to conventional base oils, extending component lifecycle significantly.
Years Industry Experience
Tons Annual Production Capacity
Cities Nationwide Network
Acres Intelligent Production Base
Operating from Zibo, Shandong—a major petrochemical hub in China—Shandong Longhai has structured a robust manufacturing infrastructure spanning 131 acres. Our strategic location facilitates direct access to high-quality Group II and Group III base oils, as well as premium imported additive packages.
By integrating fully automated batching systems with precision laboratories, we sustain an annual production output of 200,000 tons. Our advanced blending lines utilize high-accuracy mass flow meters to ensure that each formulation component is mixed exactly to specifications, eliminating variance between manufacturing batches.
To satisfy international retail and industrial clients, our production line implements the principle of metering filling. This technology maintains a filling accuracy tolerance of 1‰-2‰, whilst increasing throughput speed by 20% to 35%. This high-capacity process guarantees swift order processing, fast lead times, and highly competitive unit costs for bulk exports.
Adapting base oil indexes, packages, and viscosity grades to meet specific geographic climates and machinery conditions.
We design fully synthetic, semi-synthetic, and premium mineral formulations adapted to your market's ambient climate, heavy load ratios, and emissions requirements (compliant with API SP, SN, SL, and JASO MA2 standards).
Supports small-scale trial batches up to massive industrial exports. Packaging formats are flexible, ranging from 1L motorcycle oil bottles to 200L industrial steel drums and high-volume intermediate bulk containers (IBCs).
Comprehensive value-added assistance including label localization, container ergonomics design, technical documentation preparation, and global customs clearance compliance certificates.
From initial inquiry to final international port delivery, we execute strict milestones to protect product integrity.

After-Sales Support
Tracking shipment status, technical updates, and ongoing formula review.For global enterprises importing lubricants from China, regulatory compliance and certification are the most critical factors for legal market access and customer trust. Longhai has successfully institutionalized international quality frameworks across all departments. The company has passed ISO 9001:2015 quality system certification, ISO 14001:2015 environmental management system certification, and ISO 45001:2018 occupational health and safety management system certification.
Crucially for modern high-performance automotive platforms, our formulations carry approvals such as the Mercedes-Benz automatic transmission certification. This testifies to our capacity to manufacture fluids that protect expensive, tight-tolerance mechanical assemblies under volatile conditions.
Additionally, our brand is backed by quality liability insurance underwritten by PICC (People's Insurance Company of China), providing an additional layer of security and commercial reassurance to our global distributor network.
For custom exports, we supply complete chemical MSDS/SDS sheets, custom declarations, origin certificates (Form E, Form F, etc.), and REACH conformity documents to guarantee hassle-free container dispatch at ports globally.
Adapting oil characteristics to the diverse physical environments where two-wheelers operate.
In metropolitan areas throughout Southeast Asia (e.g., Vietnam, Thailand, Indonesia), motorcycles operate in stop-and-go traffic under high ambient temperatures. This triggers localized hot spots and rapid oil oxidation. Our JASO MA2 10W-40 and 15W-50 formulas utilize advanced anti-oxidation compounds that maintain film thickness even under extreme crankcase temperatures, preventing piston ring sticking and bore wear.
Delivery vehicles log high daily mileages with frequent payloads, subjecting gear teeth to severe shock loading. Longhai's synthetic multi-grade oils integrate shear-stable viscosity index improvers. These molecules resist mechanical cutting, maintaining their structural integrity over long oil drain intervals (ODIs), protecting gears and reducing operational maintenance costs for commercial fleet managers.
High-rpm engines demand fast oil circulation and outstanding aeration resistance to prevent micro-foaming. Our fully synthetic formulas integrate defoaming additives that maintain rapid oil flow through narrow lubrication channels. This ensures immediate oil pressure at start-up, protecting the valvetrain and cylinder walls from initial cold-start boundary friction.
The motorcycle industry is shifting toward lower-viscosity lubricants to maximize fuel efficiency and reduce carbon emissions. Standard historical viscosity choices like 20W-50 are rapidly being replaced by high-performance 10W-30, 5W-30, and even 0W-20 formulations. However, lower viscosity reduces the thickness of the oil film between moving metal parts, potentially increasing wear.
To solve this, Longhai utilizes advanced synthetic chemistry. By incorporating Group IV (PAO) and Group V (Ester) base stocks, we establish exceptionally strong surface adsorption. This chemical boundary layer protects critical interfaces even when the fluid film thickness is reduced.
Furthermore, the rise of hybrid drivetrains and integrated start-stop systems in modern scooters demands oils that maintain immediate pumpability and low traction coefficients. Our R&D team remains at the forefront of these transitions, offering global partners customized formulations that are ahead of emission compliance curves.
Technical clarifications on two-wheeler oils, industrial blending tolerances, and international logistics.
Automotive engine oils (PCMO) are formulated with friction-reducing agents designed purely to optimize fuel efficiency. However, in motorcycles, the same oil lubricates the engine, transmission, and wet clutch. Using PCMO in a motorcycle can cause clutch slippage. 4T motorcycle oils are engineered with a balanced friction coefficient (complying with JASO MA2) to ensure the wet clutch engages firmly under high loads.
Our research laboratory customizes viscosity modifiers and pour point depressants based on the destination market's geographic coordinates. For tropical regions, we select high shear-stable polymer chemistry to prevent thinning under heat. For sub-zero northern climates, we optimize low-temperature cold-cranking viscosity (CCS) parameters.
For standard 1L and 4L plastic bottle packaging with customized client labels, the standard MOQ starts at 5,000 liters per grade. For bulk export shipments in 200L metal drums or IBC containers, the minimum order can be adjusted to match standard container load metrics.
We provide complete documentation, including ISO 9001/14001/18001 certificates, GHS-compliant Safety Data Sheets (SDS), certificates of analysis (COA) per production batch, customs declarations, packing lists, bill of lading, and free trade agreement origin forms.
