What is RC Base Oil?
RC Base Oil typically refers to Refined Crude Base Oil or Recycled Base Oil — depending on regional terminology — and is a Group I base oil. These base oils are produced through solvent refining processes and contain relatively higher levels of sulfur, aromatic compounds, and unsaturated hydrocarbons compared to higher Group II/III base oils.
They are widely used in blending lubricants, especially for applications not requiring ultra-high purity, such as:
- Automotive lubricants
- Hydraulic fluids
- Greases
- Transformer oils
- Industrial oils
The Importance of Using SN150 Recycled Base Oil in Macedonia
Relevance to Macedonia
As a candidate country for EU membership, North Macedonia is aligning with EU environmental policies, including waste oil management and recycling. Using recycled SN150 helps the country:
- Meet sustainability and waste reduction goals.
- Encourage local recycling and re-refining initiatives.
- Strengthen energy security by reducing dependence on imports.
