Wild! Well that explains why it has a wide flange on the head. Now to find the part number on that bolt and it’s torque. Something tells me the normal 30 ft lbs for a drain bolt would be bad for that.

That style of drain plug on all (most) other GM engines is 18 ft/lbs, and I don't recall ever having had to replace one, or having one leak...it may be the best oil drain plug design ever IMO, so I wouldn't sweat needing to order a spare right away.

The last time I saw a crush washer on an oil drain plug was ages ago on VWs and other Euro cars. All of our vehicles for probably 20+ years have used this style of drain plug, at least near as I can recall. Some had reusable rubber or nylon gaskets, but most had the style I posted earlier and it's not just something GM uses.

My Z71 was unloaded today. The first thing I did was look underneath while it was still on the transport truck. It was built last week and it did have a metal oil pan.
 
Just changed my 2023 WT oil at 1017 miles. Metal pan. Super easy! Torqued plug to 18 ft/lbs... that seems to be the consensus.
 
Thank you. Oddly, my truck did not come with an owners manual.
There's a digital version in the HMI (radio/infotainment system) or you can download one online. Full printed manuals aren't provided by default anymore to save paper.

So glad I read this, it looked like a murder scene under the truck after the Niagara falls started pouring out. Good thing I gave myself a bit of space when pulling out the plug. One turn and 5 ish quarts came out at once. First oil change in this '23 LT! Resetting the oil life status was easier than doing a trip mileage reset, like I did in the old truck.
 
@sork I have an 09 Silverado with the plug shown with the o-ring face seal in an aluminum pan. 130k and 14+ years, never had an issues with it. IMO, best design out there. I just put it in, turn until it stops solid and done. Never looked up the official torque.
@DieselDrax Japanese cars used crush washers into the later 2010's. I have a '15 Subaru that uses them. I have also seen Honda's use them. I don't know if they still are, but it wouldn't surprise me. To me, they're kind of a PITA.

Me too, Sam! Changed my oil for the first time @ 7K a couple of weeks ago and was shocked at how fast the oil came out of the truck. My Trail Boss has the plastic plug / pan.

Anyone have a recommendation for a oil drain pan that can receive 6 quarts of oil in under 15 seconds without covering your driveway in oil? It was just hitting the top of my crappy 15 quart oil drain pan and splashing all over me, the bottom of the truck, and my driveway. I probably managed to capture ~ 3 quarts in the oil pan. 🤦

Sadly, no for the plastic pans. The plug is a much larger quarter-turn type, more similar to the oil fill cap. Fumitomo should have a version for the later trucks with aluminum pans tho.
 
I wonder if a Fumitomo drain valve would help? Maybe provide a bit of flow control. Their website claims to have 4 options that fit. I've never used one, but I've seen a lot of folks on the Subaru Forester site swear by them.

I’ve used Fumoto Oil Drain valves on my previous vehicles and it makes oil draining a breeze.

However, the Fumoto website references a 2.5L four, so something isn’t quite right
