There's an old boy around my parts who's using used motor oil on his fence - anyone heard of this idea? I thought it was dangerous to do so, both for him and the environment, but he assured me it was fine - he'd been doing it for over 20 years! Surely a can of fence paint is preferable, as well as less hazardous. He seemed to think he was doing his bit for recycling! I'm not totally sure, but doesn't it contain carcinogens and has a tendency to leach out and contaminate soil/water. Also, it made his fence black. I know oil is a great preserver for wood, but surely boiled linseed oil is different to engine oil. Curious if anyone has any views on it. Must say, it's new to me.
Come to think of it - isn't engine oil highly flammable? Will it make his fence burn down quicker than one treated with cuprinol?
