Nothin wrong with a little experimenting. I still got a semi over the onion/garlic in the coals trick. Cant wait to try that. Cant help you with fuel consumption. Does sound a little high though. I start with Kingford then go wood. Never paid attention to how much I burn, Im still a rookie and manily concentrate on keeping my temp right.
