Mozella, thanks for your staunch advocacy for the right oil.......... snip;.........

Thank you for the compliment; however, I regret to say that I don't know if it's really the best oil or not; simply that it's recommended.

There is so much "green" mumbo-jumbo, politics, marketing, and outright B.S. associated with things like this, that It's impossible to really know what is right. Every time I turn around, I learn that some politician, activist, lawyer, physician, scientist, media talking-head, corporate spokesman, or Hollywood movie star is lying to me.

But until I see something in writing from Porsche I'm gonna' stick to C40 and for me at the moment that means Motul.

Ok, last question, maybe… shop said their bulk oil, Castrol Edge M 5w-40, is a C40 spec. What’s the thoughts on using Castrol, vs Motul/LM? Is it obvious I request one of the other 2 or would you go with that since it’s in-house and doesn’t require a special ask, etc.

I have no clue Re quality/reputation of oils, Blackstone testing results, etc… if I need to be pointed in a direction to better ask my question, please let me know that too, thx!

Any C40 spec, use without hesitation.
The Edge 'M' in C40 is fairly new.
Nothing wrong with Castrol !

It says it meets Porsche C40 so I would feel comfortable using it. However I can't find it for sale in the United States. Do you know of an outlet?

 

[Payman]

I can ask the shop when I visit/make an appt. He said that’s their bulk oil.

 

[BobS]

FYI … Liqui Moly Top Tec 4110 - 5W-40 is German made and readily available via several online retailers, and their own outlets in the US.

 

[Payman]

See, another question

Should I make sure the shop does anything to the service reminder? My curiosity is, considering I’ll will have another oil change before the free dealership service year is due (I’m planning to do oil changes every 4-5k), and I don’t want to introduce unwanted issues/confusion with the dealership before that first “free” service… should the shop
reset anything or leave it alone so the service reminder continues to track to that first year/10k schedule?

Obviously, beyond that free change, I do not plan to use the dealership for maintenance services.

Hopefully I’m making sense. Thx again!

Guys, do a google search of A40 vs C40 and you’ll find out that C40 is designed to be used with particulate filters mandated in Europe. If you have a newer 718 with one installed use C40. If not, you can use A40.

Porsche has not said that A40 is OK for use in my car even though it doesn't have a GPF. Perhaps they will some day or perhaps not.

But it is comforting to know that you have announced that A40 IS OK.

My attorney is drawing up the legal papers so that you can take over the warranty responsibility from Porsche. Please post your mailing address or the mailing address of your legal team so we can send you the documents.

My attorney is still working on how large a bond you should post but it should be in the low seven figures. He wants you to know that I, along with countless other Porsche owners are grateful that we can rest easy knowing that if anything goes wrong, (even in the long term) caused by using A40 oil, you will step up and cover our repair expenses. 🤡

I think what @Mozella is requiring is a link to a source from Porsche describing what @kabob has written. I strongly suspect that American Porsche dealers are using bulk A40 Mobile One, but I have no source. I haven't rummaged through a dealership's dumpster to see if it is filled with individual oil containers, but the idea is intriguing.

 

[BobS]

This guy has a pretty informative take on the situation. One of the better explanations that I’ve found. Unfortunately, it doesn’t really resolve the main question about whether or not A40 is OK in US cars.

New oil for the 4.0 engine

With the advent of the Gas Particulate Filter(GPF)) in Europe, a new oil was necessitated, and Porsche has instituted a new recommendation for the cars over there, calling their specification C40. The oil is not backward compatible with the older A40 recommendation, but since this was Europe I...

I know for certain that my local Porsche dealer was prepared to put bulk A40 into my car which calls for C40. But not because they have a directive from Porsche saying that A40 is OK. The disappointing answer is that neither the service manager, the tech who was servicing the car, nor the guy in the parts department had even heard of C40 and were completely unaware that it was specified for newer cars.

You’re the clown if you honestly think that the differences between the two is going to damage your engine or void warranty 🙄

 

[JazzCatGab]

You know what is interesting, if you go to PorscheUSA oil page and follow it from there, you end up on the Mobile Oil page where I put in my car's info and then for the next year. For my 2019 Porsche base Cayman, it recommends the FS version, which is A40. If you bounce that up to 2020+ you get ESP X3 version, with is C40. So that's the question to ask, IMHO, is your service department using FS for 2019 and older and ESP X3 2020 and newer?

ADDED:
This from the PCA in 2020 about this question:
submitted by Pedro Bonilla [SFL] on Thu 11/05/2020 10:31 pm

Here's the story directly from the prvervial horse's mouth:
C40 spec oil is required, instead of A40 to protect the Gas Particulate Filters. All 2018 and newer Porsches state that in the manual, but those vehicles (model years 2018, 2019 and 2020) did not come to the US and Canada equipped with the gas particulate filter system so they could use the A40 spec oil.
For model year 2021 and newer, every Porsche imported to North America will be equipped with EPS and requires C40 spec oil.
C40 oil is not readily available, as you've found out, so you will have to take it to the dealer for oil changes untill you can find the new oil. Right now, very few dealers have any of the C40 oil at all but they should be well stocked before year's end.
The new oil has a part number VW5100.
That's all I have right now.

 

[Payman]

I found a indy that uses bulk C40, that was their unprompted response when I explained my make/model/year… I’d like to start with the spec oil prescribed by the manual and leave it at that going forward. Porsche hasn’t made this easy in that it’s been super confusing.

However… the timing of oil change to me is most important vs A40/C40 spec and would’ve gone with the A if no other available local option.

Well, I'd like to see Porsche say the same thing in writing.

I know already that Porsche voided the warranty on my back up camera which has never worked properly since brand new because I installed some aftermarket exhaust tips. And yes, they said it in writing.

I wouldn't put anything past them............ but if you say so, I guess I'll just ignore what the manufacturer says and go with your wisdom. Thanks for clearing that up for me.

 

[kabob]

Here guy, a nice press release stating C40 is designed to work with the new gas particulate filter engines and modern emissions. It refers to China market but the engines are global.

Unless during the install of the exhaust tips or due to the install of those exhaust tips you damaged the functionality of the backup camera, that’s a violation of the Magnuson-Moss Warranty Act. Some fancy actual lawyerin’ for ya:

Magnuson-Moss Warranty Act (MMWA)

The Magnuson Moss Warranty Act (MMWA) prevents manufacturers from using disclaimers on warranties in an unfair or misleading manner.

Just ordered a case of 6 quarts of Mobil 1 0w-40 ESP X3 C40 oil for my 2021 Boxster 2.0. It was difficult to find and I had to order a case. I wanted to have some on hand in the event that I needed to add any during the trip to Colorado for the Spring Treffen.

I scheduled my first oil change for when we get back in early May. I did ask that the, hopefully, correct C40 oil be used. Still not sure if they understood what I was talking about. Still not completely clear about what oil is correct. I assume that my car is equipped with the GPF and the C40 is correct. Wow!

 

[Payman]

Question... I just checked my next service due date info, mainly because I had the oil changed around the 2k mile mark.

It said due 11/2023 and/or 17300 miles... car has approx 2700 miles on it now and was put in service 12/21 as a new car. Obviously I'll disregard that info, but was this the result of the Indy oil change? Anything I should do to have it "corrected"? Thx!
