Not to start another oil debate, just an FYI ... came across this article at Hagerty.com that anybody with a "small, direct-injected, turbocharged engine" should be aware of Low Speed Pre-Ignition (LPSI) aka detonation. Looks like the latest oil classifications are designed to remedy the problem. I would assume MB oils are the latest spec (can anyone confirm it addresses the concerns in this article?) and would certainly use MB oil while under warranty. Here's a quick summary:

"The specifications that owners of these engines might find in their manuals are SN Plus, SP, or GF6. SN Plus was the first interim solution to LSPI and an improvement over the SN standard. The detergents and additives in that specification are based on the earliest LSPI tests completed against a Ford EcoBoost engine. GF6, an improvement on SN Plus, is the latest and greatest specification from ILSAC when it comes to LSPI prevention. It includes all of the previous LSPI testing as well as a new chain wear test from Ford, better deposit requirements, and better fuel economy requirements. The GF6 specification was only released in the last month, so it may not be on the shelves yet, but Warholic expects that GF60-rated oils should be on the shelf sometime this summer. SP is the latest specification from API and mostly mirrors the GF6 specification.
Any of these three specifications should help to prevent LSPI, but SP and GF6 are the latest versions owners should look for when making a purchase to ensure that they are getting the best for their engine. According to Warholic, Valovline will spread the GF6 and SP specification to essentially its entire line. GF6 will be used for oils up to a 10W30 weight, as that is the maximum ILSAC grade, but API SP will be in use for their heavier oils. In short order, the rest of the industry is likely to follow the same path for oil formulation."

Here's a link to the entire article for those wanting more detail. Merely sharing info, I have no interest in any of these parties, use at your own risk, etc, etc. I have also asked Blackstone oil lab for their thoughts/findings on the subject.

I see this didn't draw a lot of interest. Do we know anything more 3-4 years later? Interested in finding an API SP + 229.5 in 0W-40 (and 5W-40). Does such an oil exist and is it recommended?

 

So far, I found Valvoline 5W-40 meeting the SP and 229.5 ratings. 0W-40 meets only 229.5.

 

Mobil 1 0W-40 meets only SN specification. It also seems Castrol Edge 5W-40 meets SP and 0W-40 meets SN. Conclusion: 5W-40 meets the SP specification, while 0W-40 does not. Curious if the new Benzes have the Mobil 1 0W-40 sticker under the hood.

 

I kinda go by this.

 

Lastly, Mobil 1 5W-40 meets all of the specs.

Interesting. The 5W-40 would be for my E63. My S550 has the M273 so perhaps the lame M1 0W-40 euro is still acceptable in that one...which is what I run, and it "likes" it.

For 0W-40, Pennzoil Platinum Euro in 0W-40 meets 229.5 and API SP.

This may increase slowly over time.

 

I believe that went away at some point.

 

Pennzoil! I knew I was missing one.

So, I'm thinking 0W-40 for winter and 5W-40 for summer.

 

I do 0W-40 year-round in the S550. And 5W-40 year-round for AMG applications.

 

Well, it looks like I may be going to Pennzoil, if I can find it at Walmart. I have a stockpile of Mobil 1 to use. But I also have the C350 that uses Mobile 1 0W-40.

 

Pennzoil Ultra Platinum (NOT what the euro stuff is) might be the best oil on the market, FWIW.

Anecdotally I've heard that PP can have higher consumption but I would really love more data on that.

 

You can currently find "approved" MB oil here: https://bevo.mercedes-benz.com/

A while back and based on reading oil mfg labels it appeared most of the oils are (were?) mostly lighter weight oils (0-20, 5-30 etc). At the time, I found Mobil 1 and Pennzoil fit the requirements for my 5-30 spec. It is puzzling why LSPI hasn't had more discussion, maybe because of modern knock sensors, a longer term problem? I have not heard or seen anything from Blackstone.

 

Yeah the approved list is pretty much useless for me. Why? Because I am not interested in the list of all 229.5 oils. Pretty much every euro oil on the market will list 229.5 on the bottle. Not hard to find, at all. What I was after is API SP with the 229.5 approval. And right now there aren't many that have that, but there are a few. The presumption I was making is 229.5 + API SP would be the best oil you could get (at least by spec) for our vehicles, particularly those of us with direct injection.

Basically it brings in the goodness of GF-6 timing chain protection plus this LSPI business (which is from API SN Plus), in an oil that otherwise meets MB specs.

 

Interesting that Mobil 1 does not show up at all, unless I looked at the wrong document. 🤔

Click on sheet 223.2 for the specs but 229.5 is what I care about and probably most others with gas MB engines.

 

I swear that I looked at the 229.5 sheet multiple times and Mobil 1 was not there. Hmmmm, these new glasses are a pain!!!
