How is car motor oil recycled?

Most car owners change their oil every 2000-3000 miles. Considering the millions of miles driven each year, it adds up to a lot of motor oil to recycle. How is the dirty oil recycled? Is it refracted and made in other products? Or is is somehow cleaned of the dirt and debri and resold as new motor oil again?How is car motor oil recycled?
The vast majority of used oil (oil that is recycled) in the US is burned for energy recovery - approx 80%.


Of this, most is used/burned for energy by asphalt plants.





Space heaters are the next biggest burner of used oil - e.g., garages, and others that generate their own used oil can, with certain limitations, burn that oil in on-site space heaters.





There is some used oil that is re-refined into lubricating products. Personally, I hope the last category increases in use.How is car motor oil recycled?
There are many practical uses for used motor oil. A primary use is to rerefine it into a base stock for lubricating oil. This process is very similar to the refining of crude oil. The result is that the rerefined oil is of as high a quality as a virgin oil product. In fact, rerefining used oil takes from 50 to 85 percent less energy than refining crude oil.





A secondary use of the used oil is to burn it for energy. Large industrial boilers can efficiently burn the used oil with minimum pollution. As a result some used oil is sent to power plants or cement kilns to be burned as fuel. On a smaller scale small quantities of used oil are burned in specially designed heaters to provide space heating for small businesses.
No one knows man, it is another stupid thing that he will do, just like letting out terrorists out of Guantanamo Bay.
I dump mine in the ditch, unless i need it to burn my garbage which then I just let it burn with the trash
