RECYCLING OF USED LUBRICATING OIL
ABSTRACT
In almost all human activities especially in industrial lubricating oil is required. A large quantity of used lubricating oil is wasted in milling of liters yearly. Spent lubricating oil is recovered using methods such as Acid treatment and activated charcoal/clay method. The results obtained show that the recovered lubricating oil compared favorably with the standard. There will be a reduction or complete elimination of environment Pollution due to the present method of caroler’s disposal of spent oil is very clad. The level of lubricating oil in the market will not only be improved upon also will be sustained and easily available to the consumer Â

CHAPTER ONE
- INTRODUCTION
Lubricants are unique among the petroleum products in the market especially if the product is of high or improved quality which guarantees a longer period of usage and a relative volume of sales.
It is good to recycle the used lubricating oil in order to prevent health harzard of dumping used lubricating oil, because of small percentage of lubricating oil gotten from petroleum products, also because of the high rank of lubrications as an energy conservation measure. The idea of recycling the used lubricants was first practiced  To an extent in 1930s during scarcity of adequate supplies of crude oil Which encourage the reuse of all types of materials including the lubricating oil.
