Base Oil 4 cSt (Group III)

Description

Product Overview
Base Oil 4 cSt (Group III) is a high-performance, severely hydrotreated mineral oil offering exceptionally low volatility and high viscosity index for premium lubricant formulations. It is primarily used in advanced engine oils, automatic transmission fluids, and industrial hydraulic systems where thermal-oxidative stability is critical. The key value proposition is enabling finished lubricants that meet API Group III performance standards at a lower blend cost than PAO synthetics. With global demand shifting toward low-SAPS and fuel-efficient lubricants, this product is strategically essential for formulators targeting Euro VI, CNG, and hybrid vehicle fleets.

Competitive Advantage Spotlight
Superior viscosity stability across extreme temperatures, ultra-low sulfur and nitrogen content, and consistent Noack volatility below 13%—outperforming conventional Group I/II bases while reducing friction modifier dependency.

3. Core Industrial Applications

• Primary industries: Automotive lubricant blending, heavy-duty diesel oil manufacturing, industrial hydraulic fluids, metalworking compounds

• Specific use cases:

  • Low-viscosity SAE 0W-16 and 5W-30 passenger car motor oils

  • High-performance automatic transmission fluids (ATF) requiring low-temperature fluidity

  • Energy-efficient hydraulic fluids for precision machinery and servo systems

• Performance advantage: Compared to Group II, it reduces oil thickening by ~30% in oxidation tests; versus PAO, it offers comparable low-temp performance at 15–20% lower cost per liter.

• Efficiency gains: Enables fuel economy improvements of 1.5–3% in WLTP testing due to lower high-temp-high-shear (HTHS) contribution.
