What's the longest cook that you've done without added lump?

ColtsFan

18 hours with lump left to burn

I had a Boston Butt go 23 hours once on a LBGE.

Wolfpack

I’ve done a 20 hr before

23 hours any lump left?

My very first cooks on my XL went 30 hours. Butts over brisket then slow roasted a couple whole chickens.
Lump quality and cook temp plays a major roll in this.

20 hours on my large easy with lump to spare....

XL, 18 hours first cook, 5 hours second cook 3.5 hours 3rd cook. All from the same initial load, still had lump left over. Time does not include lighting, coming to temp or shut down.

I’ve never had to add lump to finish a cook on the XL, or the L for that matter. Well or any size. I think when you close the dome, lump multiplies somehow.

Longest cook I’ve been able to do on my large was around 15hrs or so. Had lump left but the fire had burned In an odd pattern so it didn’t ignite about a 1/4 of the lump. I take that back, there was probably a couple handfuls of lump left. Not 1/4

If you take the time to stack the lump in a certain way you can probably get 24hrs out of 1 large egg fully stacked. The key would be to fill the bottom with larger chunks and gradually work to smaller pieces further towards the grate. That would help keep it from collapsing. Also airflow is the biggest component to how long it will last. More airflow, the hotter you get, the faster it burns.

I'm convinced that my XL could easily go 48 hours at 250 or so.  I've loaded it up to the platesetter on a Friday afternoon, cooked burgers at 450, then closed the vents down to get it down to 250 and put on a brisket about 10 PM, pulled the brisket about noon, cooked some ribs, and then opened up the vents to get it to 350 and did wings.  I started cooking at 5 PM on Friday and finished at 7 PM on Saturday with about 30 minutes at 450 and a little over an hour at 350.

You’re not putting in enough lump IMHO. I can go close to 24 hours - maybe more -  on the large with no careful stacking. I dump it in and light it.  If you’re only getting 15 hours you’re not putting in enough fuel.

Big pork shoulder took 28 hours on my xl at 220 until internal temp of 190.  a tiny bit of lump left, like a half gallon volume. I piled it up for sausages direct the next day.

Longest I can recall on my Large...

if you go low and slow direct you can go 2 to maybe 3 times longer than indirect. this was what i started with on a 16 hour butt cook and what was left after the cook going direct on a raised grid
