Daniel, Whenever you first fire up for the day you need to pay really close attention to the flue pan. Sorry I did not mention that before, slipped my mind. It will usually foam up bad right then and let you know how much oil you will be needing to add. I usually put in a drop or two every time I put wood in the fire box or more if needed. I use a squirt ketchup bottle, because it lets me control how much goes in without getting burned
