Abstract

The effects of varying ratio of used engine oil and sulphuric acid, with kaolin as contacting agent, on reclaimed oil properties was analyzed in this study using response surface methodology. Results revealed optimal used engine oil-acid ratio of 1: 6.3. The reclaimed oil obtained from this optimal ratio has viscosity at 100°C, viscosity at 40°C, viscosity index, specific gravity, pour point, flash point and total acid number as 12cst, 120cst, 92.87, 0.85, 9°C, 177°C and 0.53mg/KOH respectively. Also, the engine oil reclaimed from this optimal mix gave values of viscosity at 40°C, specific gravity and total acid number so close to that of a standard grade/fresh lube oil.
