Used motor oil has lead and other contaminates, further the oil hardly evaporates, and in any rain/snow event a portion leaches into the soil and eventually the ground water over time. IMO its equal to pouring used motor oil on the ground, just over much longer period of time, disregarding the potential increase in flammability of the wooden fence sees...... his wife was busy painting the fence (rural lifestyle property) with this really smelly black goo. I asked what it was that smelt so bad.
It turns out he has been painting the fences with the used engines oils from his vehicles - most are diesel. That might sound cheap, but it actually makes good sense.
Engine oil and diesel combined will preserve the wood, and stop the rot, as well as keeping away any bugs or mosquitos etc. His fences looked brand new.
This is not something I would do.
