Where to get rid of dirty oil?

I dont know about recycling of used oil

But down here we use the used motor oil on the wood decks of the wagon/trailers. We brush it on in the fall since they get stored outside during the snow days. We do not have enough indoor storage for the wagons/trailer.

Keeps the wood from rotting. The last trailer we had, the steel rusted away in 15 years but the wood looked like new.

bad idea, would have been fine 20 years ago; heck the government even oiled dirt roads with it. These days if one drop gets spilled and someone sees it they will dig "until its gone"

makes no sense to me it comes from the ground anyway
