AFAIK, in good faith, this is how I determine if the oil to buy is recommended by Porsche
  • Go to Recalls | NHTSA. Click on the Vehicle Tab and enter your vehicle, like 2018 Porsche Macan
  • A new screen comes up with all the models available. Follow the row of your trim level to the column Manufacturers Communications. In this example lets pick Porsche Macan. Click the number. There will be alot that comes up.
  • Now you got to go through them and find the communications about oil. Scroll down for things like Engine and Engine Cooling.
    • In the example pick 8/22/22, thats not it :(
    • 7/30/22 Click on Associated Document.
      • Click on Associated products and you will see if your car is there. It should be because you chose the right row above, right?
      • Click on PDF and its Overview of Approved Porsche C40 Engine Oils (31/22)
    • You're not done. Keep going back in time you will See C30, C20, and A40 each with their own communications.
  • I would not presume this is forever. They can change. Its not like there wasn't approved oils in 2014. These appear to be the latest in the NHTSA data base.

Will be doing the first oil change in my '23 S and noticed there are not many options when it comes to Porsche C30 oil as called for by the manual. The 3 that I am currently trying to decide between are Mobil 1 European Car Formula 0w-30, LiquiMolly top tech 0W-30, or Pennzoil Platinum Euro LX 0W-30. Curious if anyone has good experience with any of these oils.

What if you don't have the particulate filters? Do you still use the C spec oil?
It seems like from what I've been reading the C spec oil reduces the friction modifiers so as not to hurt the particulate filters, but in the US we don't have those filters so wouldn't you want to use the oil with more friction modifiers? (The older A spec oil)

Good morning all, piggy backing on this thread, I am a bit confused

Noticed that my oil level is a tad low while driving the past week, sitting at the mid-point between Full and Low. As a preventative measure, with a few lengthy road trips coming up over the next few weeks, I plan to keep a quart of oil on hand, to top up (a little at a time) only if/when needed.

Here is where I am confused
  • Model is 2021 GTS (Canada), picked up in December 2020
  • My first oil change in December 2021, dealership used 5W30 Mobil 1
  • Second oil change in December 2022, dealership used 0W30ESP

Available to purchase at my local auto supply store is Mobil 1 ESP 0W30, which shows as Porsche C30 approved

Is this the correct oil to pick up ?
Why did the viscosity change between 2021 and 2022 oil changes, both done in winter ?

Thanks

new owner of CPO 2020 gts. reading through the manual, this thing eats oil. ive watched my oil level slightly go down over a few k miles - i am going to have to top up at some point before my next service.

according to the manual, spec is C30 is 0w30 or 5w30. there is a sticker on the engine cover noting mobil 1, but not viscosity.. so i got the euro mobil 1 part.

but how do i know what viscosity to top up with till the next change? there is no sticker or marking anywhere noting what is in there now.

thanks for any input.
 
#67 ·
yes thanks for this.

after reading through this thread, it appears the mobil euro formula for c30 is only available in 0w30, even though the manual lists 0w30 and 5w30. i am going to assume (hopefully correctly) that a top up with 0w30 mobil 1 euro spec adds to exactly what is int he car already (cpo purchased, but no reciept on the change prior to sale. only a stamp of the service in the manual).

im glad this was nice and simple.

thx for the link to this thread.

I recently had my first annual service, which was basically the first oil change.

Looking at the invoice, I noticed the oil used was Liqui Moly. If I remember correctly Porsche says to use Mobil 1 in the manual as well as the sticker under the hood.

Shoul I be concerned or is this normal? Should I ask the dealer to change the oil again?

Liqui Moly is just fine. It is a German oil. I’ve used it in my past Macan.

Mobil 1 is readily available in the US at your local store. Liqui Moly I always had to order online.

Is there any real difference in using ESP
0w-30, Vs 5w-30? If you don’t live in an area with temperature extremes? (2018 Macan)
In theory the 0 weight oil will pump to the engine faster at any temperature. (Compared to a 5 weight oil) Most engine wear occurs at startup where there is no oil for a moment.
I want the oil to pump as fast as possible when I do a dry start to minimize any additional wear...

How much additional wear is being induced? that's any bodies [sic] guess, it may not be enough to make a difference if you're the type of person that is trading the car in at the 5 year mark.
I'm not sure I'd want to own any Porsche vehicle that had over 100k miles on them, but some people do and I'd want to take every advantage I can get no matter how small.

To answer the ESP question, the ESP formula was designed to protect the gas particulate filters that are fitted to most Porsches (And other manufactures) in Europe. The Macan in the US does not have these filters so it provides no benefit other than to potentially satisfy a warranty claim (Dealer could potentially say you used the wrong oil)

At the end of the day, it's not really going to matter much what you put in to be honest. Full Synthetic oil in 0W-30, 5W-30, 0W-40, 5W-40 from any brand. I know we all like to obsess about special oils and what not (I certainly do) but let's be honest, as long as the oil is clean and changed regularly the engine isn't going to care one bit.
^^ Ignorant statement.
Modern direct injected (DI), high pressure turbo charged (or super charged) engines have specific engine oil requirements. Perform an internet search for - LSPI piston damage. This is just one example of what can happen if one uses the incorrect engine oil. It is not just about viscosity.
Over on the Alfa Romeo Giulia forum, there is an engine autopsy thread showing what happened when a fellow had an indy shop change his engine oil. They used an older spec Liqui-Moly oil that was not API SN+ or SP rated. The engine suffered broken ring lands on one piston, caused by LSPI. The rest of the engine, the tops of all the pistons, no problems. Heed this warning and use only Porsche approved-rated lubricants and other engine fluids. You don't know better than the engineers.

We don't have a Alfa though... Any of these modern oils today are fine in our Macan, there hasn't been 1 case where someone damaged their Macan from using the wrong brand of a quality oil...
Low oil, yes. too much oil, yes. Leaving the oil in too long, yes... Wrong brand? no...

EDIT, I checked the Walmart super-tech oil (Not that anyone here would use that) but it is even SP rated....

I said nothing about choosing an oil by brand.

My point is, Porsche, and most other manufactures advise using an engine oil with certain specifications, not just viscosity, for very good reasons.

You stated, "At the end of the day, it's not really going to matter much what you put in to be honest. Full Synthetic oil in 0W-30, 5W-30, 0W-40, 5W-40 from any brand.

I stand by my response, that your above statement is ignorant.

Porsche and other manufactures also make decisions about oil specifications for not good reasons. But thank you for your opinion.

Hello Macan Forum. I am new to the forum, but not new to the Porsche brand. That said, I went waaaay down the rabbit hole on selecting the best oil for me to use in my brand new 2024 Macan GTS that meets the C30 specifications as outlined in the owners manual and the sticker under the hood. There is a very knowledgeable gentleman named Lake Speed Jr. (no I am not making this up), who spoke at a recent PCA event, and there are two reasons why Porsche made the switch from A20,A30,A40 to C20,C30,C40. One only impacts European cars with GPF (gas particulate filters), but the other reason impacts all direct injection Porsche's, is a phenomenom known as LSPI (low speed pre ignition) (see: lugging the motor at low speeds, or when carrying larger payloads). So I reached out to him and asked him what is the best oil I can use during the warranty period (I want to use a Porsche approved C30 oil)? Mobil 1, LiquiMoly, etc. He flat out said the best oil based on his research for our cars is the Motul 8100 x-clean+ , C30 approved.
Here is his YouTube channel. All his work is research based and tested. Hope this is found helpful to the community.
His video on Mobil 1 re: LSPI issues

EDIT EDIT EDIT w/ UPDATE
Hello - Additional research between Mobil 1 ESP 5W-30 (Porsche C30 Approved) and Motul 8100 x-clean+ (Porsche C30 Approved) has been performed, and looking across the Porsche C30 Approved oils, the updated Mobil 1 ESP 5W-30 has the required API SP standard.
"API SP is the new minimum engine oil standard developed to address the critical needs of today's engines; including chain wear, Low Speed Pre-Ignition (LSPI), and deposit formation. API SP is the foundation for the ILSAC GF-6 specification but does not include fuel economy. API SP is available for different viscosity grades."

Well, I suspect, based on his scientific review of the Mobil 1 products and their high Calcium content (around 3800ppm), which has a direct correlation to LSPI failures based on his extensive research. Motul has a low Calcium content (around 1500 ppm). BTW, with Motul meeting Porsche standards (C30 designation), they do recognize and approve it as well. Again, my question to him was very clear.... I said I want the best available oil within the approved warranty parameters, and his response was Motul. (which wasn't even on my radar screen prior to asking the question)
 
#85 ·
You then have a 2.0 Macan. So you will want to use a C20 oil. I'm sorry I cannot comment on the calcium levels of Mobil 1 0W-20ESP, as I am unsure. I do know that the C40 oil from Mobil 1, as stated in the review is almost 3X the recommended calcium levels. If it is important to you, you could send off to get a Blackstone test performed on your oil and if the Calcium is any higher than +/- 1,500ppm, then you will want to switch out to protect the motor from LSPI. I looked it up for you, and Motul makes a C20 oil. Again, this is not a recommendation or advice, but here it is for your reference.

Hello - New to the forum and my original post above has been updated to reflect corrected and updated research and information rewgarding the best C30 oil for 2024 Macan GTS. This information has been validated by my original resource, Mr. Lake Speed at Speed Diagnostix. He can also be found on YouTube as The Oil Geek.
I am sorry for any confusion my original post may have caused and hope that this corrects that.

I’ve used Mobil 1 since new every 5k miles. I just did an oil/filter change at 75k. In those 5,000 miles I lost 1/2cup oil.

Hi and thank you all for great info in this thread, appreciate it as a new(er) forum user. I have a 2022 Macan base 2.0 engine and ESP X2 0W-20 is the recommended oil with Porsche C20 approval.

I need to do a second oil change (car only has like 10k miles on it, working from home and all), first one was at Dealership (included) last year, and this year nice dealership is asking $750 for an oil change (called and asked twice, yes $750 for an oil change for what seems to be an Audi / Golf engine in Porsche clothing.)

Called the highly respected independent shop and asked and they charge $280 or so, but given I have done all my oil changes myself in the last many cars (BMWs, etc.) I have owned, I thought I should do this myself anyway. But was going to get the independent to do the work, you know, for paper work and all in case I have a warranty claim at some point. But the independent on the phone said 'oh the new standard is C40'... and that concerned me.

From what I am seeing , difference in C40 to C20 (or C30) seems to be the weight 0w40, 0w20, 0w30 (plus other probable changes as noted in this chat)... but I have not seen a C40 that is 0w20.

I think I am just going to go ahead and do the oil change myself with locally purchased (Autozone has them) Mobil1 ESP X2 0W-20 oil and 06L115562B filter.

re: Fazmoto - You are correct in stating that your car will need C20 oil. In your engine bay there will be a sticker that clearly states this. C20 = OW-20 or 5W-20 oil. The indy shop that you are speaking with is referring to C40 = 0W-40 or 5W-40 oil, which is the Porsche oil used in V8 Porsche cars like the Cayenne, and maybe some of the GT cars like GT3 and GT3RS. The V6 Macan's require C30 oil, either 0W-30 or 5w-30. In looking at the correct C20 oil for your Macan, the Mobil 1 ESP 0W-20 is one of the approved oils that will protect from LSPI (low speed pre-ignition).

Greetings all,

I recently bought a brand new 2024 Porsche Macan S, which is a great car, to say the least. I'm a DIYer and I change the oil myself, I only visit the car dealer for the service. However, I live in KSA and the weather here is extremely hot and the owner's manual says that I can only use C30 oil 0W-30. Usually in other car brands, the user manual would recommend a variety of oil viscosities that can used which gives you wider options and choices. The real challenge with this C3O type of oil is that it's hard to be found and even the car dealers here in KSA don't sell it, they use large barrels for service only instead. My question is, can I use other viscosities such as 5W-30 or OW-40? As far as I know, there were some 5W-30 oils were classified as C30 oils but Porsche updated their list of approved oils to have only 0W-30 oils.
