China Factory Advantages & Operational Scale

Our state-of-the-art production base in Shandong provides key cost and chemical engineering advantages, integrating advanced raw material refining, automated batch compounding, and high-throughput packaging solutions.

Advanced Automated Blending

Equipped with computerized, fully enclosed blending lines using precision mass flow meters. We achieve an accuracy rate of 1‰ to 2‰. This system accelerates production speed by 20%-35%, ensuring rapid delivery times and batch reliability.

High R&D Investment

We reinvest over 5% of our annual revenue directly into laboratory innovation and university partnerships. We design custom chemical structures optimized for shear stability, oxidative resilience, and minimal viscosity-temperature deviation.

Certified Compliance

Our quality system is verified by ISO 9001-2015, ISO 14001 environmental, and ISO 45001 occupational health parameters. We hold formal Daimler-Mercedes-Benz approvals for transmission and motor oil reliability.

Technology & Innovation Whitepaper

The Evolution of Passenger Car Motor Oils (PCMO)

Modern internal combustion engines (ICE) run hotter, use turbocharging with gasoline direct injection (TGDI), and utilize exhaust aftertreatment systems like gasoline particulate filters (GPF). These demands make historical API SN or SL lubricants insufficient under heavy operational stress.

The transition to API SP and ILSAC GF-6 standards was engineered to combat Low-Speed Pre-Ignition (LSPI), an abnormal combustion phenomenon that can cause catastrophic engine damage. Shandong Longhai's API SP formulations incorporate advanced calcium-magnesium detergent packages that suppress LSPI while providing timing chain wear protection and improved fuel economy.

Hybrid Vehicle (HEV/PHEV) Lubrication Needs

Hybrid powertrains introduce unique challenges: frequent start-stops and lower average operating temperatures. This leads to condensation, water emulsion, and fuel dilution within the crankcase. Our modern fully synthetic 0W-16 and 0W-20 formulations feature robust corrosion inhibitors and dispersion additives to keep water droplets in suspension, maintaining chemical integrity even during short trips.

Key Viscosity & Additive Technologies

  • Group III+ Hydrocracked Base Oils: Provide high viscosity index (VI) and low volatility, reducing oil consumption.
  • PAO (Polyalphaolefin) Blends: Offer outstanding low-temperature pumpability in sub-zero climates down to -45°C.
  • High Sheer Stability Index (SSI): Viscosity Index Improvers (VII) resist mechanical shear to keep the oil within its target viscosity grade.
  • Low SAPS Technology: Formulated with reduced Sulphated Ash, Phosphorus, and Sulphur to extend the lifespan of catalytic converters and GPFs.

"Our laboratory simulations indicate that our advanced fully synthetic SP grade motor oils lower friction coefficient by up to 18% compared to standard mineral SN grade oils, translating to an average fuel efficiency increase of 2.4%."

Operational Application

Macro Industry Solutions & Local Scenarios

SCENARIO A

Urban Stop-and-Go Fleets

Delivery fleets operating in high-density urban areas experience frequent idling and low operating temperatures. This causes fuel soot accumulation and sludge. Our SP formulations offer soot dispersancy to protect pistons from abrasive wear and maintain performance in stop-and-go driving conditions.

SCENARIO B

Extreme Temperature Logistics

Long-haul logistics lines crossing extreme climates—such as sub-zero mountain ranges or hot deserts—demand robust shear stability. Longhai fully synthetic diesel and gasoline motor oils maintain stable viscosity and film thickness at high temperatures while ensuring rapid cold-starts at -40°C.

SCENARIO C

Heavy Duty Industrial Systems

For heavy industrial operations, our L-CKD industrial gear oils and anti-wear hydraulic fluids are designed to resist micro-pitting, oxidative degradation, and chemical breakdown under extreme pressures (EP). This protection helps extend equipment lifespan and reduce plant maintenance overhead.

Technical FAQ

Frequently Asked Questions

Q What makes API SP gasoline motor oils superior to older API SN formulations?

API SP oils are specifically formulated to address Low-Speed Pre-Ignition (LSPI) in modern turbocharged gasoline direct injection (TGDI) engines. They also provide enhanced timing chain wear protection, superior oxidation stability, and improved fuel economy compared to older SN-grade oils.

Q How does Shandong Longhai ensure batch-to-batch product consistency?

Our 131-acre facility utilizes computerized automated blending lines with precise mass flow metering to ensure blending accuracy within 1‰ to 2‰. Every production batch is tested in our quality control laboratory for viscosity index, shear stability, flash point, and TBN before packaging.

Q Can you customize formulation parameters for specialized regional markets?

Yes, our R&D team offers custom formulating to meet specific regional requirements. We can adjust viscosity index parameters for extreme cold climates (e.g., sub-zero pumpability) or optimize additive packages for high-dust, high-heat operating environments.

Q Which certifications and standards do your engine and industrial oils meet?

Shandong Longhai holds ISO 9001:2015, ISO 14001, and ISO 45001 certifications. Our products meet or exceed API, ACEA, and JASO specifications. Additionally, we hold official approvals from Mercedes-Benz for automotive lubricants.
