I don't change my car oil anymore, but I do change the oil in my bike. I called an auto parts store (it's a chain, but I don't know if it's a good idea to name them) and asked if they took used motor oil. They do. On a lark, I asked if they take automatic trans fluid since I have a few cans that I'll never use. They take that too and they told me that they put it all together. So, I asked, what about brake fluid. Same thing. It all goes into one big barrel.
That's good news for me since I don't know what else I would do with it, but it did get me to wondering... I can see that used motor oil could be filtered and re-used in other applications, but when there's trans fluid and brake fluid (and who knows what else) in the batch, can it be re-used for any other purpose? Does it just get thrown away? What do they do with it?
