Base oils & Lubricants

Base oils & Lubricants
Base oils are essential components used in the production of various lubricants, including engine oils, transmission fluids, and greases. These oils serve as the foundation for creating high-quality lubricating products.

The selection and volume of base oils directly influence a lubricant’s functional attributes. Characteristics including how it reacts to temperature changes (viscosity-temperature relationship), its ability to resist oxidation, and its friction management capabilities are markedly affected.

Key Quality Indicators of Base Oils and lubricants:
  1. Viscosity: This fundamental property gauges the oil’s resistance to flow. A crucial factor in determining how the oil performs under different operating conditions.
  2. Viscosity Index: A critical measure that reveals the extent to which the oil’s viscosity is affected by temperature variations. Higher viscosity index values signify better performance across a range of temperatures.
  3. Sulphur Content: An important parameter influencing both the lubricating efficiency and the environmental footprint of the oil. Lower sulphur content is generally preferred for reduced environmental impact.
  4. Flash Point: This is the specific temperature at which the oil begins to emit flammable vapors. It’s a vital safety parameter, indicating the oil’s volatility and combustion risk.
  5. Pour Point: Refers to the lowest temperature at which the oil maintains its fluidity. Essential for ensuring reliable performance in cold environments.
  6. Colour: While often overlooked, the colour of base oil can be an indicator of its purity and suitability for certain applications. Different oil types exhibit distinct colors, influencing their selection for specific uses. Usually, the clearer the colour – the better quality.

Base Oils Classification: Base oils are broadly classified into five groups based on their composition and performance characteristics. DYM Resources specializes in the following:

Group I — Mineral Base Oil:
  • Less than 90% saturates.
  • More than 0.03% sulfur.
  • Viscosity-index range of 80-110.
  • Suitable for a temperature range of 0-65°C.
  • Solvent-refined, making them the most economical choice.
Group II — Semi-Synthetic Base Oil:
  • Over 90% saturates.
  • Less than 0.03% sulfur.
  • Viscosity index of 100-120.
  • Hydrocracked manufacturing process.
  • Better antioxidation properties and clearer color.
Group III — Synthetic Base Oil:
  • Greater than 90% saturates.
  • Less than 0.03% sulfur.
  • Viscosity index above 120.
  • Severely hydrocracked for purity.
  • Often described as synthesized hydrocarbons.
Group IV — PAO (Poly-alpha-olefins):
  • Synthesized base oils.
  • Broad temperature range, ideal for extreme conditions.
  • Commonly used in high heat applications and cold environments.
Group V — Special Base Oils:
  • Includes silicone, phosphate ester, polyalkylene glycol (PAG), and more.
  • Often mixed to enhance oil properties.
  • Esters are prevalent, known for high-temperature tolerance and detergency.

Mineral base oils can divide into paraffinic and naphthenic, depending on crude oil and content of these types of molecules.
