Just curious, but why is “Ukraine” in the first descriptive line?

tyrbo

From the URL, ua is Ukraine.
This one (cz) is Czech Republic: https://www.mobil.com/en-cz/passenge...1-c40-gt-0w-40

Couldn't find an NA page or anything.

I assume that’s where it’s made (not great for consistent supply chain). Good to see CZ source too…

Same.

I’ll feel a bit better about the current out with the old but only half of it procedure for the RS.

TXshaggy

Thanks, that makes sense…was on my mobile not looking at the URL.

jmartpr

and I would imagine dealers will be clueless about this new Mobil 1.....

I just returned 12 quarts of the "old" stuff to Autozone. They have a 90 day return policy....just put 8-9 quarts in the car a few months ago (Drained, filled, ran, re-drained, re-filled).

GrantG

Indeed, but I've made a couple aware of it (including Suncoast)

Just got a case (of old stuff) for Xmas. sigh

Got this from Porsche today!
Wonder if they’ll reimburse me for the 8 liters of C40 I’ve got stocked up?

Also, reason must be some damage
to to existing engines due to the C40 oil.

Dear Porsche owner,

We would like to inform you that the previous specifications C40 and VW 511 00 regarding the engine oil approval for your Porsche XXX will change on 01/02/2024.





From this date onwards, you will find the engine oil composition previously used at the dealership under the new C40 GT specification approval.





What should you do?

If you currently have a container with engine oil approval C40 or, alternatively, VW 511 00, purchased before 01/02/2024, you can use it without further restrictions.





When purchasing a new engine oil container, it must exclusively comply with the engine oil approval C40 GT from 01/02/2024.





Please note that using the wrong engine oil may cause engine damage.



Porsche recommends Mobil 1.



If you choose to use engine oil from Mobil 1, you can recognise the new engine oil approval directly from the especially created design, see appendix.





If you have any further questions about choosing the right engine oil, we/your Porsche Centre will be happy to answer them.









What are we going to do?

As part of your next workshop visit, we will replace the sticker featuring the name of the previous engine oil approval in the engine compartment with an updated sticker in addition to this information.





In addition, we will update your digital Driver’s Manual in the PCM (only valid for 992 GT3 as of MY22, 992 GT3 RS as of SOP, and 992 S/T).





If you no longer own this vehicle, please write the name and address of the next owner on this letter and return it to your Porsche Centre, postage-free, so that we can inform the present owner of the vehicle accordingly.





Yours sincerely,

Porsche Norge
