The Mobil 1 5w40 oil does not carry the Porsche approval (it is actually made for Mercedes). While it is very likely fine to use, why would they put in an oil that doesn’t carry the appropriate approval?My 2018 Cayman just got serviced up here in Washington State and they put in Mobil 1 5-40. I was using 0-40 for the first 20000 miles. I was a little surprised but this is a highly recommended shop that works on German cars only so I trust them on this.
Given the mileage, Raceready has a MY18 requiring a A40 spec, not a C40. From the Mobil site:The Mobil 1 5w40 oil does not carry the Porsche approval (it is actually made for Mercedes). While it is very likely fine to use, why would they put in an oil that doesn’t carry the appropriate approval?
Aside from a 5w40 specifically for Diesel engines, this is the only 5w40 I see on Mobil 1s site:Given the mileage, Raceready has a MY18 requiring a A40 spec, not a C40. From the Mobil site:

0W-40, 5W-40 and 5W-50 should be OK.
C40 is required for cars w. GPF, I doubt if any of them in the wild has 30k mi.
Interesting. Doesn’t appear to be offered here in the states (can’t find it anywhere on the Mobil 1 website) and the link you provided appears to be for the Chinese/Taiwanese market.![]()

Checked the owners manual and it recommends A-40 ,0-40,5-40 or 5-50. It must be the weather up here for them putting in 5-40.The Mobil 1 5w40 oil does not carry the Porsche approval (it is actually made for Mercedes).

Right I was just saying I was not aware of mobile 1 making an A40 spec 5w40 oil. I know their 0w40 and 5w50 are A40 spec but not the 5w40.Checked the owners manual and it recommends A-40 ,0-40,5-40 or 5-50. It must be the weather up here for them putting in 5-40.
Good find on the 5w40 A40 spec. Makes sense they don’t offer it here since it would just be redundant to the 0w40 offered which covers all the major German brands.I looked into it too! As I showed above, the 5W-40 is described in the Taiwanese site to be specced for the Mercedes, VW and Porsche A40. I believe this is the 'M Formula' or 'European Car Formula' sold in the states. The first link I gave is a US site and talks about Porsche A40, Mercedes etc etc.
However, if you go to sales, the Porsche reference drops out of the picture! If you chase the 0W-40 formulation, you see the Mercedes alongside the Porsche spec. Strange!...
Personally, I wouldn't worry about it, I would tell the mechanic not to do it again and use 0W-40 or else... I can see an indie servicing Mercedes, Porsche and exotics buying 5W-40 by the 55 gallon drum and using it indiscriminately, and I wouldn't bellyache too much. Just see whether they may have a 55 gallon drum of 0W-40...
But... I live in Houston!...0W?
