Waste Oil?

Hey wanted to see what others are doing with waste oil at the moment. When oil prices were sky high a few years ago we had it unloaded for $0.50/ Gallon to us! Now the same people want to charge me to come out and get it.

Anybody got any cheap good ideas? Oil furnace, trade to someone with oil furnace, and etc? Please no dumb answers like "put it on the road"

We have Several barrels full.
