hi salam and happy ramzan
i have always wondered what mechanics do to the used engine oil ? do they do something to it and resale it unscrupulously ? or they just pour it somewhere... ?
got this info from a site
What is recycled motor oil used for?
Used motor oil can be reprocessed into fuel that can be used in furnaces for heat, or in power plants to generate electricity for homes, schools and businesses. It can also be used in industrial and utility boilers, blended for marine fuels, and other uses. Used motor oil can also be re-refined into lubricating oils that meet the same API specifications as virgin motor oil.
SO WHAT IS DONE TO IT IN PAKISTAN?
