Reviewing the specs, Mercedes has changed the recommended oils for the new M264 engine. Digging into it a bit further, they are recommending oils that are MB-Approved 229.51, 229.52, 229.61, 229.71. There are no weight recommendations as these range from 0w-20 to 5w-40. What they do all share in common is low SPash (Sulfur, Phosphorus, Ash) in order to protect the emissions components. Usually, low SPash oils are reserved for cars with particulate filters. Now, coming from the United States, I've read that our version of the M264 will not be equipped with a particulate filter. First, am I correct that the US versions do not have a particulate filter? Second, if that's the case, am I correct to assume we can use 229.5 oils that are medium SPash? I'm not even sure what the dealers stock although they likely have low SPash for the prior diesel cars.

It's been mentioned on here that Dealerships stock only one bulk oil... 5-40 to satisfied the blueTec models... so... they use and recommend the 5-40 in ALL MB engines... from what I can gather from Mobile 1. Their 0-40w European formula meets and or exceeds MB 229.5 recommendations . I'm no chemists . but I've had no issues using the 0-40 w Mobile 1 the past serval years..

OP ~ re your PM request. Times have changed since 2016. At that time I would not put 229.51 product anywhere near a gasoline engine of the time. It provided inadequate protection for those designs with it's low additive treat. (sorry for late response ~ just had an op)
The M264 & engines of it's ilk are designed to operate on low SAPS oils. Earlier gas engines are not. (less aggressive cams now etc. etc.) Low SAPS oils are still a bit of a compromise. They sacrifice a little engine protection for the sake of the emissions system. The M264 series engines should run on MB-Approved 229.51, 229.52, 229.61, 229.71. products. (229.5 products would give better engine protection but be hard on the emissions gear)
With the huge new listing of different category low SAPS oils from ACEA plus US Dexos 1, Dexos1 Series 2 & Dexos 2 describing the products would do nothing but confuse people that are not tribologists to no avail whatever. Finding the correct products on the shelf is difficult enough.
While under warranty it is crucial that you let the dealer service the vehicle with the correct oil. Don't want any arguments about potential claims.
What us oil company types are recommending for maximum engine life with low SAPS products is that you don't go for the manufacturer's extended drain interval. No need to change the oil filter at half distance but just change the oil at half the recommended interval.
This is an example of the product you should use & is available and at a fair price. Trust this helps
I have a 2019 GLC 300 4matic (274 engine) with 22,000 miles. Driven on average 3 times a week.each time over 100 miles mostly "interstate" in CT and MA. I do the oil changes myself.
What oil(s) and oci do you recommend. I hope to keep car "forever".
Thank you,
This oil can potentially void your warranty on a US 2020 model with the M264 engine as it's a 229.5 oil that has moderate SPAsh but as Glyn said, it works for 2019 and earlier models.
I have 2018 GLC 4 MATIC bought certified with 6K now 14K. Before this guy I had ML 2014 BluTec and used only 5W-30 229.52 Spec
There are so many scary stories when dealers didn't change or used wrong type oil on OM642 BT and engines were seized,
owners had no luck proofing dealers fault. and cars were last for good.
So I decided to do it myself (keep receipts) by using OM filter and recommended spec for oil, used Liqui Moly 2331 Leichtlauf High Tech 5W-40 Engine Oil which is 229.5
Attaching the oil report after 4.3K. Looks like engine is well protected and oil can go longer, next time I'm planning to change it at 5.5K and do another test.
This is the one(maybe only one) that I can find in big stores, e.g Canadian Tire, that is Mobile 1 brand and meets 229.51 or 229.52 requirement.
Mobile 1 ESP 5W-30.
Is that good for Canada? is 5W-30 the best SAE grade?
As for the manual, it says use lowest SAE viscosity, so is that saying to use smaller number SAE grade? like grade 30(e.g. 5w30) is better than 40(e.g 0W40). My understanding is that oil with bigger number is thicker, so smaller number is thinner so that can achieve better fuel consumption.
Copying from the 2020 GLC manual(USA & Canada):
All models 229.51, 229.52, 229.61, 229.71*
*Recommended for lowest possible fuel consumption (lowest SAE viscosity class in each case; observe possible restrictions of the approved SAE viscosity classes).
To achieve the lowest possible fuel consumption, it is recommended to use the engine oil specifications marked in the table for the lowest SAE viscosity class. Possible restrictions of the approved SAE viscosity classes must be observed.

Without getting into the nitty gritty, in your example 5w30, the 5w is the viscosity of the oil at cold temperatures. When it's cold it'll act like a 5 weight. The 30 is the viscosity at high temp, where it'll act like a 30 weight oil. Note, this does not mean it is thicker at high temperatures but that it acts like a thicker oil would at high temperatures.
So to compare the two oils, the 0w40 will flow better at lower temperature and will protect better at high temperature. However, due to its thicker viscosity at high temperature you will have more pumping loss making the car overall slightly less fuel efficient. I don't remember the exact numbers but I think they are within the margin of 1% to 2%. I believe the 0W-20 is also MB approved if you really want to be as fuel efficient as possible. However, I would take the hit on fuel economy and use higher viscosity oil for better protection as long as it meets requirements.
For the above list, https://bevo.mercedes-benz.com/bevol...229.52_de.html, it seems Mobil 1 ESP x3 0W-40 is better comparing to ESP 5W-30
- it flows better when the engine is cold, especially in Canada winter
- anti wear is better when engine is running at regular temperature
I prefer engine protection over fuel efficiency of coz. However, Mobil 1 ESP x3 0W-40 seems only available in Europe?
Looks like Mobile 1 ESP 5W-30 is the only one available here.
Could anyone confirm that this oil is good for 2020 GLC300 M264?
I received my 2020 GLC300 in May and checked with the dealer what the car came with from the factory - 5W30 229.52 - it can be purchased from the dealer, and the thinking ( read Internet posts ) seems to be that for the Canadian market it is made by Mobil-1 - Mercedes has a marketing deal for their F1 team with Petronas, and they could be supplying some of the Asian markets - in Europe they might have another brand making it.
In the end as long as the oil is on the bevo page ( and yes Mobile-1 ESP 5W30 is there ) they can't claim any warranty issues - still it would be nice to find the best oil for our climate - in my previous C300 I used Mobil-1 0W40, and never had any issues.

Thank you for the info.
I called the dealer part department, what they are using and selling is Mobil 1 5w40, 229.5 (NOT 229.52), they said one oil fit all Mercedes cars including AMG models regardless new and old. It is 1 litre per container. I will go and check it out when purchase the oil filter and drain washer there. But I do not think I will get the oil from dealership as it is not 229.52.

When I was at the dealer a month ago to pick up touch-up paint, I talked to the parts department, and just like you found they only had 5W40 229.5, and which point I made an observation that since 2019 C300 has M264, and those had to have oil changes by now, either they were using wrong oil and entering wrong data ( since they have to say which oil was used ), or the parts person had no clue - at that point I really wanted to know what was in my car and got to meet the service manager - he informed me that the car had 229.52 and that they have it in stock, and the parts person had no clue what they were talking about - I plan to call them on Fri. to see if 229.52 is in stock as told by the manager and see how much it is.
Right now the Mobile-1 ESP is on sale at $35 for 4.8l till end of today - may order it on-line and pick up in store on Fri. and return it if I end up selecting something else ( thinking of Motul 8100 X-Clean+ that I might be able to pickup locally ).
Here is a link to a video of a fellow that has done some
When I was at the dealer a month ago parts told me the same thing - only 5W40 229.5 in stock - since 2019 C300 was the first to use the M264 I wanted to find out what they were putting into those - exchanged e-mails with the service manager and was told that they use 5W30 229.52 and that it is in stock - plan to call the service department on Fri. to find out if that is the case. I am thinking of using Motul 8001 X-clean+ and might be able to source it locally - here is a link to some comparisons including the Benz 229.51
On a related topic, I have not found any videos of people doing the oil changes on the 264 - some on 274 and that involves disconnecting the air intake - in 264 looks like there are pull pins on the turbo intake that need to be removed to get to the oil filter. Have spoken to a friend mechanic and he suggested that there are O-rings there, and his recommendation was to change them when doing the oil change - since the 2020 are under warranty I suspect very few people are doing their own oil changes - if one knows of a video or some good pictures please let me know.

I did try to remove the air intake plastic. Yes, it is different than 274 GLC: it is from left to right and it has two elbows.
However, it is pretty easy and almost the same as 274 GLC, although I spent a few hours to figure it out. Fun fun. I will post some pictures in my thread about this.
using this, same I have been using for years on all the Mercedes vehicles I have owned or still do
and did the oil change and filter on the new one at 1400Km on our own about a week ago
2020 GLC 43 has same new oil requirement/spec as GLC300 though, the 229.5 old school 0W40 Mobil 1 is not on the list anymore.

I didn’t get the car for fuel economy, both oils are just as good, they will work just fine, maybe the new stuff will get me an extra bit of savings in fuel economy, but it will not be detrimental in how it lubricates.
Called the dealer and they do have the Mercedes branded 5W30 229.52 in stock - was told that only 1L containers are available ($16.80 cdn) , so the pricing is not as good if they could sell 5L. I think the price is in line with Mobil-1 ESP when not on sale at CT.
P.S. Sorry for the double post above - it looked like my first post was not submitted - not sure if that happens often.

.
I also believe that no harm to the engine, but I am not an expert on this, I can only follow the manual and the official spec. There is different between "it should be okay" and "it is absolutely okay"
I bought the same oil as yours and planned to use it. Until seeing this thread and did some research, I returned those oil.
One of my theory(it might be wrong) is that as it is turbo engine, the exhaust air would go back into the engine, so Mobil 1 ESP, cleaner oil, maybe good for the engine.
I just went to my local dealer, went to the parts counter, said I want to do an oil change and I need oil, hands me a bottle of oil, it’s packaged as Mercedes oil, has the 229.5 on the front of the label, I tell them no that’s not what my manual says to use it says use 229.51, looks at me and says, well this is what we use, take it or leave it.
seems even this dealership don’t know or don’t care, if it’s .5 or .51
I at least changed it at around 1500Km, not the 5 or 10 thousand mark as they suggest for the first oil change, and I am leasing this thing....lol
