I have about 150 gallons of #2 heating oil that's about 10 years old. Its in a tank in my shop. Called around locally and been advised I need to have it disposed of because its probably no good as heating oil any longer. Have one quote at $850 to pump it out and dispose of, waiting on another quote. Can this be burned in a waste oil heater? Anyone have any better suggestions than paying for disposal? I want to make sure it's handled in an environmentally responsible way but I'm hoping there is some use for it so I'm not just paying for disposal.
