When I was a kid the neighbor would pull his car over the ditch next to the road and change his oil there. No need to jack up the car and messing with disposing the oil.

I always wondered why our well water had those pretty rainbow colors

I put mine in a 55 gallon drum. Which last week the daughter says is about full. I’ll probably run a Craig’s list and see if I can get a couple bucks out of it to someone who has a waste oil furnace.
