Abstract
This research mainly focuses on the physico-chemical properties of recycled used lubricating oils in order to determine their quality as lubricants. The lubricating oil was recycled using activated clay as an adsorbent with sulphuric and nitric acid. The density, specific gravity, viscosity, viscosity gravity constant, PNA analyses (Paraffin, Naphthenic, Aromatics), and flash point were determined for the recycled lubricating oil. The test results of the physicochemical properties demonstrated the effectiveness of clay activated by sulphuric acid as the optimum for enhancing the lubricating oil. The predicted paraffin (P), naphthenic (N), and Aromatic (A) fractions PNA analyses of each sample provided good values for high paraffin compounds. The sulphuric acid-activated clay effectively performed a better adsorption process, thereby recovering valuable oil from used oil samples of comparable quality.

Key words: Lubricating oil, Recycling, PNA Analysis, Clay, Viscosity
