Allegedly, used motor oil contains heavy-metal contaminants ( I notice that mechanics routinely wear protective gloves now ).
If you spread it on unpaved roads, as a former employer used to do, it can percolate into wells and aquifers. Microbes won't eat it, can't 'bio-remediate' it.
It's like the methyl tertiary butyl ether ( MTBE ) that was banned from gasoline.
It's permanently ruined some municipal water supplies around the country.
There's always a background muttering about banning Low-Lead AVGAS, something that would be the death-blow to civil aviation.
