This study addresses recycling of used lubricating oils treated using different methods involving rmtreated clay as the control sample, clay activation and calcined clay methods. A recycling process of the used lube oil was carried out which eventually led to comparison of results of the recycled oil with the fresh lube oil using ASTM standards. Tests carried out on the used, fresh and recycled lube oils include: flash point, kinematic viscosity at 40 and 100°C, respectively, specific gravity/density, appearance and total base oil. The results show that recycled lubricating oil had the following properties: flash point was 227°C for the calcined clay, 229°C or activated clay and 224°C for nntreated clay, compared with 204°C for nntreated waste oil. Also Ttal Bse Number IBN) gave the followiug: 6.25mg KOHg-' for calcined clay method, 6.24 mg KOH g-' for activated clay and 5.56 mg KOH g-' for uutreated clay method, compared with 4.41 mg KOH g-' for uutreated waste lubricating oil. This gives the recycled lube oil the potential to be reused in car engines after adding the required additives
