Hello,
I am Avinash, i'm doing my 8th semester mechanical engineering.
I found a ppt on refining of used lubricating oil. I was wondering if some one can help me get a better ppt, about 13 - 15 slides. I don't mean to offend the person who has made that presentation. In that ppt, the last few slides are just pictures, so that doesn't cater to my needs.
