New AMG 507 approaching 1,000 mi and the dipstick is a tad low when cold. Figure I'll go warm it up and see where it's at.

Anyone know which viscosity would have came in it? Can't find mention of it in manual.

Thanks !

Ingenieur

0w40

But it probably came with 5w40 but that is only available from the dealer in tbe required 229.5 spec

It's in my manual?

Thank you. I'll look in the manual again so I know where it's listed.

My local Walmart stocks 0W-40 Mobil 1.

I've always tried to not mix oils in other vehicles and never ran Mobil 1 before.
Without knowing for certain if it came with 0W-40 or 5W-40 is there any concern in adding 0W if it does contain 5W ?

Ingenieur

No issue

What is the level?
Oil must be hot and check ~5 minutes after shutdown
Do it a few time to get a repeatable level
Insert the dipstick, wiggle it, let set for 10 seconds then read

Just looked at the manual
Can be checked cold as long as the vehicle has been shutdown for > 30 minutes

The cold vs hot levels are close in most cars
When hot it is expaned volume
When cold more has drained into the sump
Pretty much offset each other

Actually, your maintenance booklet says 229.5 or 229.51. Mobil 1 European Formula 0W-40 is the approved 229.5 oil and Mobil 1 ESP Formula M 5W-40 is the approved 229.51 oil. Most dealers use the 5W-40 because it is required by all diesels since 2004 and simplifies stocking. Some people report it also lessens the chance of valve train noise in the M156 engine.

The 5W-40 is most likely what your dealer will be using. I think it's a better choice. Just make sure it's Formula M. (The M stands for Mercedes.) Mobil 1 makes another 5W-40 but most places stock the Formula M so it shouldn't be harder to find than 0W-40 European Formula. If you use 0W-40 make sure it's European Formula (Mobil 1 makes other 0W-40 oils). Look on the back for either 229.5 or 229.51. If it doesn't say that, it's the wrong oil.

The BEVO sheet I linked specs only 229.5 for NA
It is current as of 01/2014

Page 8.

The book calls for it and the dealer only uses it.

Your link allows it in Europe but not the US? Sounds like a typo to me, especially because the documentation that comes with a US car specifies it.

Ingenieur

Not a typo and is the official MB fluids chart
M156 World except western europe only 229.5
Western europe 229.5, 51, 52

The approved 5W40 is the non- esp
It is 229.5 spec this spec is current as of 3/2014
http://www.mobil.com/USA-English/Lub...a_M_5W-40.aspx

229.5 is worldwide except western europe
This tells me the 0w40 is better but the 51/52 is spec'ed in WE due to more stringent emission standards... Not because it is better protection

But in reality makes no difference
One may perform better in some ares, the other in different areas
Net zero sum

At my most recent oil change, my dealer's service department had big drums of 0w-40 and 5w-40. They gave me my choice between them but recommended the 5w-40 (based on the climate, lifters, etc.).

You will be fine with either of those synthetic Mobil 1 oils.

whoover

Your link says, "The prescribed engine oil specifications (MB sheet) are documented in the vehicle´s manual." This is a way of saying that the documentation that comes with the car takes precedence.

And why 229.51 is ok for the engine in Europe but not in the US doesn't sound like an interesting question? 229.51 only works for kms, not miles?

But I don't know a dealer that doesn't use 229.51 oil for this engine, at least in this area. Why don't you take them all to court? It'll give you something to do. "They put oil in my engine according to my manual, but I found a link on the internets that said they can't use that oil if the car's odometer reads miles. I've been damaged."

Ingenieur

When I called MB USA they said use the BEVO site since it is continuously updated where as the manual is not

Western europe emission standards are more stringent
So the 51/52 low ash, etc stuff has been approved for use
Apparently reluctantly since its use is not mandated for the rest of the world though

They are MB specs
Someone should ask them,but I'm sure they have their reasons

whoover

Even though our manual says it's approved and all the dealers use it? OK.

Ingenieur

Not sure what the dealers use
Only know what the BEVO spec lists
My manual does not list 51 only the 5
Does that mean I can't use it?

Imo the 'regular' oil is better that the esp
The esp lubrication performance is compromised in favor of emission performance

For me 0w40 > esp 5w40
Now if you could get the regular 5w40 I would use that

In reality, no difference

Is there any actual evidence that by using or not using MB spec'ed fluids, that it makes any difference? I've seen it mentioned quite a bit, but other than to say "MB says you must, so you must", I haven't seen anything to support using spec'ed fluids only.
Since coming to the MB platform, I've been amazed at the lack of actual technical info generated by someplace other than MB.

whoover

That makes no sense whatsoever. These oils have lower sulfur, phosphorus and ash ("SPAsh"), which in addition to not clogging diesel particulate filters, means less abrasive particles, acids and sludge-forming compounds in the combustion byproducts. Why would any sane person want more ash and sulfur in their engine? The "emission performance" merely means oil that doesn't produce stuff that could clog a filter. You don't have such a filter so that stuff "enriches" your oil. It's yet another reason that dealers use this oil for our engine.

whoover

These engines are very hi-tech (mirror-surface spray of iron instead of liners in the aluminum cylinders, for instance), run very hot and are expensive when they break. Why would you want to ignore AMG's specification as to proper oil? Who would you trust more? The company that has to pay for warranty repairs or a company trying to sell their oil?

Ingenieur

To you...makes no sense 'to you'
Could be construed as you don't understand
Beyond comprehension
Missing the point
Lol
MB says otherwise since their official chart specs the non esp EVERYWHERE EXCEPT western europe

So, since I prefer the regular oil I'm not sane lol
Simmer down lil cowpoke

There have been tests between regular vs esp
The regular lubricates better
Esp helps emissions at the expense of lubrication
It's a 'green' world now

Use whatever you like
Sand and heat activated epoxy, whatever
I'll use what BEVO specs for my region/type

Dealers use drums of the regular non ESP 5w40???

whoover

Care to point me to these tests?

D C

To me, they are one and the same. An oil company selling you stuff, or an oil company selling the MFG stuff (which gets sold to you). If you are using a quality oil, it shouldn't matter if it's MB approved or not. So that's why I'm asking.
Has there been ANY failures or damage attributed to using non MB spec'ed fluids? And not due to some gross negligence on ones part, like running it with no oil or something like that. With the number of M156 engines around the world, there should be some samples.

EDIT: Additional researching has left me without a definitive answer, but even places like BITOG says your an idiot if you don't use MB spec'ed oil especially in an AMG built motor.

Ingenieur

I have my MVI
Oil changes
4308 miles 5w40 july 10
7941 5w40 july 11
10833 5w40 late june 12
14448 0w40 late june 13
All the same dealer
20881 0w40 june 2014
Different dealer
For some reason changed to the 0w40
My guess? No regular 5w40 available
Only ESP

Ingenieur

Using a good non-approved synthetic oil of the same wt/API should not cause 'failure' but may affect longevity and long term wear
But I doubt it as long as the intervals are per the book

But why not use the spec oil?

whoover

Again, I'm not sure why an owner would purposely choose a non-approved oil for their engine, so I suspect there aren't that many samples. And if one did and suffered an engine failure, I don't think he'd announce it to the world.

MB publishes the specific qualities their engineers request and certify oils that have these qualities. I, for one, see no point in using a different oil, especially since doing so will void my warranty.

whoover

Interesting guess, but I'd still like to see the evidence. The spec sheets of the two 5W-40 oil are pretty much the same, except that the non-ESP has 50% more sulfated ash. That's not really conducive to better lubrication.
