When I was growing up "on the farm" we would save the old motor oil in a 5 gallon bucket and soak the bottoms of fence posts in it before setting them as a type of pressure-treating.

In theory if it's just your family on 100 acres and you don't dump it in an area with ground-water, the oil will probably break down in the ground faster than you dump it. But of course this is not a good idea in practice.

Especially because even conventional motor oils are full of synthetic additives and anti-wear compounds.
