Base oil is the primary raw material in the production of lubricants, greases, and other petrochemical products. At RAHA OIL, we supply high-quality base oils derived from carefully refined crude oil, ensuring excellent performance in automotive, industrial, and specialty applications.

Base oils typically make up 70–95% of a finished lubricant, meaning their characteristics directly influence the efficiency, stability, and lifespan of the final product.

What is Base Oil?

Base oil is produced through a series of refining processes, including:

Distillation – adjusting viscosity and flash point
Solvent Extraction (Furfural) – improving viscosity index
Dewaxing (M.E.K process) – enhancing low-temperature performance
Hydrofinishing – removing impurities such as sulfur and nitrogen

The result is Solvent Neutral (SN) Base Oil, classified into grades based on viscosity at 40°C, such as SN 150, SN 350, SN 500, and SN 650.

Main Types of Base Oil

1. Paraffinic Base Oils (Group I & II)

Paraffinic base oil (PBO) is a refined mineral oil with outstanding lubricating performance.

Key Features:

Superior lubrication and wear protection
Excellent high-temperature stability
High oxidation resistance for long service life
Good solubility with additives

Applications:

Engine oils (automotive & industrial)
Hydraulic fluids
Gear oils & compressor lubricants
Heat transfer fluids

2. Naphthenic Base Oils (Group V)

Naphthenic base oils (NBOs) are derived from crude petroleum with unique solvency and low-temperature properties.

Key Features:

Exceptional solvency for additives
Excellent cold-weather performance
Naturally low wax content (minimal dewaxing required)
Stable color and appearance

Applications:

Metalworking fluids
Transformer oils
Adhesives, sealants & printing inks
Specialty greases & lubricants
Process oils in rubber and plastics

3. Synthetic Base Oils (Group III, IV & V)

Synthetic base oils (SBOs) are chemically engineered for superior performance compared to mineral oils.

Key Features:

Wide temperature range (extreme cold/heat)
High oxidation resistance → extended oil life
Low volatility → reduced oil loss
Excellent shear stability under high stress

Applications:

High-performance automotive engines
Gear & transmission lubricants
Long-life industrial greases
Hydraulic fluids for extreme conditions
