Mercedes Benz M276.8 oil choice process

[Daytona]

That's a recipe for engine trouble. Seen it a few times. Stick to the correct approvals and HTHS.

A statement so vague, as to have no meaning at all.

Engine "trouble"? Which kind of engine, a lawn mower?

"Correct Approvals"? Which exact ones? A few different maybe apply, even generic or equivalent.... How about ones that didnt' even exist when the engine was made? You know for sure for sure that VW 511 would kill it in an instant, Dexos specs too? HDEO?

Not many oil fall outside of the viscometric "requirements"

As well as Mercedes even allowing "Standard Oil" OCI indicator reset options.

So exactly what "engines problems" you personally documented with M276 and Mobil 1 10w-40, or was that just a general caution based on not knowing?

 

[Daytona]

I really don’t understand this. Numerous MB229.5 oils available in Wal Mart, exceptional oils, but yet, lets use oil that has additives to swell your gaskets etc.

I guess it comes down to experience. That's why you "don't understand".

Trollolololol, You cant explain it yourself even.

Experience? Please, enlighten us with that experience!

One of the deadliest thing is lack of basic knowledge combined with confidence.

 

[FranklinJL]

how often do you run it in the quarter mile?

I track it about 20 times a year, temps get alot higher than anything you're doing in a 1/4 mile. Temps will get into the 230s low 240s. Your 3.0 V6 will never get that hot in a 1/4 mile

have you ever done a UOA?

VW 511 will not, neither will a 502/505, but we are again talking about approvals that were not present when these engines came out. I've seen multiple M272 and M276 knocking, intake manifold getting stuck and disintegrating in the engine in the case of a M272, overheating an M272 due to bad lubrication, multiple adjuster issues in M276, timing chain stretch and noise in M278.

 

[Daytona]

Those are completely different architecture engines, a 90 degree w/balance shaft and a 60 degree DI engine

I'm not buying it.

 

[edyvw]

Are you typing for exercise, because you're sure not using your brain. Here goes another "expert" who never really has anything tangible to add. Anyone who spent two days here could compare M1 10w-40 basic specs to ACEA and understand how it's applicable.

Like I said, though I watered down original expression.

There are M272 variants with DI. You don't have to buy anything since I am not trying to sell anything. What does their architecture have anything to do with it? It is a free country and you are free to use what you want though.

 

[Daytona]

No, apparently I can't just "use what I want" because when I said so it was really important for you to contradict me with baseless claims of "engine trouble" with my oil. Then when asked, you cited a bunch of random Mercedes engines with minor sensor issues to back up your bold claim. None of it was related to Mobil 1 High Miles with it's 4.1 cP HT/HS anyway....not even in theory.

So the nitpickers here who dwell almost entirely in theory, seem to NOT have one in regards to how poor of a choice this oil is in these engines, ALL of which I currently own. No theory, no data, not even a PDS or VOA or UOA. What have you posted to earn any esteem?

I'll be waiting on that DI M272 variant. https://www.fcpeuro.com/blog/the-definitive-guide-to-the-mercedes-m272-and-m273-engines

You are constantly bringing up KV100 and HTHS. Approvals are much, much more than that.
No one gives a crap what you use. They responded so other people know.
The problem for you is that you are looking confirmation bias. By saying “my oil,” your insecurity just comes out.
As far as people are concerned here, you can use olive oil on sale at Dollar store.

Does anyone have a valid reason Mobil 1 HM 10w-40 wouldn't pass ACEA A3 sequence? Anyone? It used to carry A3 when it was self-reported, what has changed? Why can't members with such a vast posting history come up with a technical argument against this oil? They claim to know all about mfg test sequences, but really only know they exist, not any of the details that they think are so relevant. No, all they can do is criticize, attack and show how weak their game is in the process.

What a sad situation, for a technical forum to be dominated by ignorance and bullyism. These veteran members are anything but an asset to the site.

Break the cycle of sadness yourself then. Why don’t you answer the question and be an asset?

 

[nthach]

Dragsters use stupid thin oil, it never reaches high temp.

And so do Hondas and Toyotas.

The only way to find the answer is to ask Mobil. Why don't you go ahead and do that?

It used to carry A3 when it was self-reported, what has changed?

Again, ask Mobil.

Nobody here knows why Mobil dropped ACEA A3, but you expect someone here to tell you why Mobil dropped the cert?

 

[Kalle.J]

Currently yes. But they realized "the issue" / negative aspects.
JASO GLV-2 0w16 and 0w20 releasing 2025 will replace GLV-1 0w8 and 0w12.

Wow. What a dumpster fire. What I do not understand is that Mercedes is pretty open in terms of approvals, meaning there are lots of good oils on the shelf at your local auto store or Walmart that meet the spec. These oils are good for street use and even HPDE use. Drag use is actually harder on the transmission and driveline than the motor, in terms of temperature and force. Personally, unless you are aware of the replacement cost for a Mercedes automatic, I think it is nuts to drag race that car. Unless you simply have money to piss away, then good for you, seriously,

I use 15w50 in the two old BMWs in my sig. Per the original owners manual that viscosity is within spec for those cars, so I have no issue with M1 15w50. But I would never use it in an application where it is not specified. To name one thing, cylinder to wall clearances on the newer motors are much tighter for environmental / emissions reasons and I have no idea - and why would you risk it given the plethora of really good 229.5 oils out there. - if there will be issues with the rings using an oil that is so much heavier than specified. We are not talking about going from 5w20 to 5w30 here. We (wife) had three MBs over the years, a C240 sedan, and two E wagons, one a 210, the other a 211. The typical viscosity was something like 5w40 under the 229.5 spec. That is a robust oil.


As far as heavy duty use, that is a fair concern, but more of a concern if you are running that little Toyo or Subie coupe with the flat four that uses vegetable oil (0w20) and loses oil pressure in sharp turns. There I would think of a change - probably more is needed than just oil selection- but Euro cars are pretty conservative on the spec and even with drag racing you are not putting sustained heat into the oil.

Meanwhile it is your car so use what you want. You don’t need permission and this is the internet, so there is an ass for every seat.

Have a good weekend.

Petty bickering lock.

It's simple ask questions share answers. However asking a question only the manufacturer can answer just wastes everyone's time.
