Used oil

What do you guys do with your used oil? We have ours picked up by Safety Kleen. They use to pay for it but now charge to pick it up. Was talking to the guy that picked it up and he said a lot of the major oil companies bought from them and reprossed it. Like Mobile One, Valvoline to name a few. Said it cost less to process and was better than the crude. Don't know if this is true or not does anyone here know for sure.
