What is longest 250F temp time on a Large you ever achieved without refueling?

Options
I never tested it but for the memorial day brisket cook, im thinking about testing this out to see if if can be done.

I have run the XL with a full load of lump at 225-250 for 26 hrs with lump left ober.   I have run the large with a full load of lump fpr 12 or so hrs with lump left over.

I am lookimg for anyone who has used the Large, full load of lump, at a low and slow cook that lasted 24 hrs without needing to refuel.

Anyone out there successfully do this?

    I cook pork butts all the time for 18 hours at 225-230 with lump left over.i would think using good lump that 24 hours is possible,but I can't say I have done it.

    i once filled the thing to just about max.  did a pork butt at 225 for damn near 20 hours (i now do them higher).  my buddy was bringing his brisket to eat as well (he had a BGE too) but it wasn't done.  when they arrived i pulled off my butt, tossed on his brisket, and we drank and ate for eight hours before it was ready.

    next day we cooked a chicken, say 350 for a couple hours.  day after that, steaks and burgers at high heat.

    i don't think there is any chance of a filled large ever truly running out of fuel. 

    24 hours is not even a challenge

    Sweet!  Thanks for the info @Darby_Crenshaw and @Captainjimpark.   That settles it,  For the Memorial Day brisket cook, i am doing a full packer, with a vee or chicken rack in the middle to tent it so it fits in the Large lengthwise, for 24 hrs.  I am pretty Eggcited to again witness the efficiency of the BGE

    I've gone 24 hours at 200-240 temp, in winter. started the grill at 5 PM, brisket on at 11 PM, dinner at 6 the next day.  (Most briskets I cook, though are around 12#, so I run them around 275-285, and just cook them during the day for dinnertime eats)

    I can hit 18 with the lump still at the top of my firebox.  I will start it at the top of the ring. So I'm assuming it can go 24.

    I did 24 hours often in FL with BGE lump on a large.  I clarify two things here: Lump (I don't know that Cowboy would make it????) and region (I now live in CO at altitude and have not done 24 hours yet, but I will give it a try this weekend).

    Never made it to 24 but did go 22+hrs at around 240-250*F on the dome with more than enough for another 2 hours.  Thinking back to when that cook happened, I'm sure the lump was Wicked Good Weekend Warrior.  FWIW-

    You might have to use a wiggle stick about halfway through the cook, but 24 hours is theoretically possible with a blower type controller. 

    I suspect that blowers force extra air out of the egg ... air that you had to use lump to heat.  If you're not using a blower, then I suspect that the airflow is less, and thus, the lump usage is less.

    it isn't "theoretically possible with a blower".
    it's possible with the BGE, no accessories req'd

    Rockwood fully loaded to where the OS had to be pushed down to fully seat took a 20 hour butt smoke then did some chicken breasts, a turkey, and burgers. Total out at about 28 hours of cooking.

    I have hit 19 hours with enough lump left to grill chicken three more times before refilling...

    @Darby_Crenshaw ...  Let's try it this way: With a blower, it is theoretically possible to maintain 250 degrees for 24 hours.  A few months ago, I calculated a lbs/hr consumption rate using my FB200 for repeatablility, and then, extrapolated the time for consumption of 10 lbs of lump.

    Without a blower - naturally aspirated - the egg will most likely exceed 24 hours.

    Guess it depends on what is filled to.  I go to bottom of spider and 18 to 20 hours with some lump left.  Using royal oak lump.  225 to 250 with auber controller

    @SmokinTiger81... it also depends, if you're measuring by volume, on the brand of lump you're using.  Ten pounds of Rockwood will fill a large to the bottom of the notches in the fire ring.  Never used Fogo, but others have said that it's very dense and will burn longer than other brands.

    I usually put lump up to the top of the firebox or maybe slightly higher.  I've never been able to go beyond 12hrs.  I was cooking a brisket a while back using Ozark Oak lump and was running uncomfortably low at about 5hrs into the cook.  Gonna smoke a butt all night long on Thur evening...certainly hoping I don't run out of lump.
    The problem with a problem is that you don't know it's a problem until it's a problem, and that is a big problem.

    @RajunCajun ... if you only fill to the top of the fire bowl, then all you have to cook with is five pounds of lump.  Since the fire goes out on a 250 degree cook with about one pound of lump left in the egg, you're only using four pounds to cook ... four pounds will yield about 12 hours.

    Fill it to the bottom of the notches in the fire RING and you'll not have to think twice about finishing that butt on one fill.

     You are all awesome.  I was a little concerned before, thinking about eggsperimenting with the large but as the guy in Mexico said to George, "Gringo.....i've got no more concerns...."
