Here I pour my old oil and any old gas or brake fluid ect, in a 10 gallon heavy plastic container and take it to one of our recycling stations. There they have a tank for such material and I can pour my stuff in it. Its then sold to reprocessors who in turn recycle what they can and the rest gets used as fuel for big furnaces and such....Pehaps you need to check around for such a place in your home area.
