I have only used Kingsford so far. I want to use lump but don't have good access to it. As soon as I can find a 30 gallon drum I will make my own because I have nearly unlimited oak.
I digress... I have gotten easy 14 hour burns with the Kingsford. Still some left when I closed it down. Two weeks ago I did a 8 hour or so cook... shut it down (I thought) but had left the ball valve open a little. The next morning I noticed a little heaat coming out so I opened her up, gave the fire grate a shake, put in a few more briqs, and did another 6 hour cook without a problem.
