As a home mechanic, I generate a modest amount of waste oil. Between my vehicles, small-engine equipment, and oil from work I do for others, I suppose I generate 20 gal/year. All the places that sell used oil have free collection/drop off (I think it’s state law), but I do one better and get $0.80/gal for it at my local scrap yard, where they use it to run their smelter.
However, we visit my sister in-law every six months or so, who lives near Allentown…the other side of the state. They’re really hurting financially, and I would gladly forgo the $16/year if I could give it to them in a condition that would allow them to run their furnace on it. I don’t know the exact heater make/model, but doubt it was designed from the start for WMO…and I suspect it’s pretty old.
So, what would be needed to convert it into usable home heating oil? Could I just pump it through a diesel fuel filter and call it a day? Obviously I’m not going to break the bank to clean up such a small quantity of oil, but I’d be willing to spend up to $50 to have something to do. (Oh, and I suspect the ecological aspect might be brought up. In defense, let me say that I’m proposing diverting it from being burned on one end of the state, to another. I don’t see where this is any worse–or better–than the default setting, though it might not be a red-taped “approved fuel” or whatever.)
