I used to add it to my fuel oil tank. I remember reading that the EPA
considered that a legal reuse of old oil. I can't do that anymore now that
I've switched to heating with natural gas since fuel oil is no longer
available.

However, here there's a simple solution: The city has streetside recycling.
Just put the oil in a container marked "Used Oil" and set it in the recycle
bin out at the street on trash day. When the recycle truck comes, they pour
the oil into a tank on their truck and set the container back in the empty
recycle bin. I assume they sell the oil to a recycler.
