I just started tinkering with this a day or two ago. The reason it took so long to light is, as you can see, I did not have the air up enough to pull the oil. It seems to take about 2 psi to pull it up. I plan to have a bigger metal tank to store it in and have it elevated. Not sure how this will work but I plan to put an old smoker in the shop with some baffles to hold the heat in and then vent the exhaust through a hole in the side of the shop. I hope a fan sat next to the smoker will push enough heat throughout the shop. It doesn't produce any smoke but I'm sure there is stuff in the exhaust that I don't want to breath in. Still a work in progress.
The EPA says this is the best way to dispose of used motor oil.
