Abstract: This work presents the result on the regeneration of used engine oil using industrial bleaching earth and activated carbon as the bleaching agent. The used oil undergoes acidification and bleaching steps to remove the aromatic content and to improve the colour and quality of the oil. Analysis carried out showed that when the formulated grades were compared with standard grade (fresh oil). Formulation A showed a better quality with a viscosity of 53.16cP at 40?, specific gravity of 0.932 and total acid value of 0.54 using industrial bleaching earth. On the other hand, formulation E gave a fair quality using activate carbon with a viscosity of 40.41cP at 40?, specific gravity of 0.883 ad total acid number of 0.59.
