I bought an OWB last year after having filled up my furnace take with #2 fuel oil (500 gal). Now of course I'm not using the oil to heat my house and was wondering if I needed to add a preservative to the oil like you do with gasoline, or if it can just sit in the tank. I don't want to sell or pump the oil out, it's a nice back up if we have to leave for a couple of day.
