I just received my oil change kit from Suncoast and the drain plugs are different now. There were 3 plugs with the 991.2 kit, two of which used 8mm hex bits and one that used a 10mm hex. The 992 kit contains only 2 plugs (and their washers). There's a small plug with a 6mm hex now (and an unusual washer than could be hard rubber that does not seal against the flange. And then the larger plug now uses a Triple Square XZN bit (12 points of 90-degrees each) that I believe will be size M10 (9.8mm from point to point). A T50 bit fits in it (but is slightly small and has only 6 points, so only uses half of the contacts).
I am hoping someone can post the Workshop Manual pages for the new GT3 oil change. I'm pretty sure we'll be seeing new torque specs (and possibly new oil volume as there is a new CF oil tank to replace the old Aluminum one).

I’ll be watching this thread closely as I am very curious how they have changed this. GrantG, you are a great asset to the RL community, thank you for enlightening us and spearheading these DIY projects
The BS that goes into all these design changes for a simple drain bolt is baffling. Why not simply use a 17 mm external hex bolt with a copper washer; one on the sump and one on the tank?
Pretty sure we need to use C40 oil this time (even in US). I’m using Liqui-Moly 4110…
That's the oil I'll be bringing to my dealership for oil changes. It just arrived this week from FCP Euro. I'll have it done in about 2 weeks. I'll also send the factory fill to Blackstone Labs for a used oil analysis to start establishing a base line.
Update on the XZN Triple Square Bit size: We need M9, not M10 as I originally guessed (this is an oddball size that may not be included in all socket sets).
And in case it wasn't clear the small plug with the 6mm hex is female on the plug, so we need a male 6mm hex bit (like Allen Wrench).
Also, the oil filter seems to be same as 991.2 GT3 and that uses a Hazet 2169-10 filter wrench (the "-10" is the low profile version of the 2169 to get access to the filter).
I'm still trying to find torque specs and other info from the Workshop Manual - I'll post if I find and appreciate it if others would too
Total Engine oil quantity for Brand new engine (not oil change):
Filling capacity 8.1 Liter (Oil Change volume will be a little less - guessing 7.1L, but I will confirm this later)
Torques: #1. Below: Drain plug on oil pan M16 x 1.5 - replace sealing ring Tightening torque 31 (23 ftlb.) Nm
#2. Below: Oil drain plug on oil tank M12 x 1.5 Tightening torque 20 (15 ftlb.) Nm
Oil Filter (guessing same as 991.2 GT3 which is 20Nm or 15 ft-lbs with bead of engine oil on the rubber gasket). Also good to partially fill filter with oil - only part filled as it sits horizontally.
It seems like #1 is the new weird XZN Triple Square replacement and on the 991.2 there was very little access to this plug location (hoping there is more room on 992). May be very difficult to get a torque wrench on this location (and fit a normal sized socket as well). I'm starting to wonder if Suncoast sent me the correct part or maybe Porsche is trying to make this a very difficult part to replace/torque for the DIY mechanic.
Grant - What tool are you going to use to reset your maintenance light? I know that wont come on for another year even with your early oil change but you probably have a plan.
I am looking for something that will work with my 981 and 991.2 as well as my GT3.

My dealer resets for free, as long as I provide receipts for parts and Self-Maintenance Log that includes which services I perform at what date and mileage.
BTW, in the 991.2 the third drain plug location was the large plug (with 10mm hex) just above and to the left (rearward) of the number "2" here:
It's interesting that they no longer want us to drain from here also (you get a little more out from #1, but this big one is WAY more accessible and easier to torque (40Nm or 30 Ft-lbs in the 991.2).
Silly question but did the workshop manual post somewhere or do you have a link handy? I have been trying to find a copy to read while I wait for the car to come across the Atlantic. Those documents are the most interesting to me.

I wish I had access to it. A dealer service guy nicely took snap-shots from his computer for me, but I don't know how to get access myself. If someone can get their hands on a digital copy, that would be great to have. Maybe there is a paid subscription one can order?
