All,

I recall a recent thread on oil for our AMGs.

This past weekend I looked for the above oil, and came up empty handed at Auto Zone, O'Reily's Auto parts (sp?) and Walmart. These stores all carried 0W-40 but no 5W-40...

I finally located 5W-40 at Pep Boys which cost $12.95 or $3.00 more than 0W-40...

The oil I purchased was Mobil 1 5W-40 Emission System Protection (ESP) Formula M. Is this the correct oil for our AMGs?

The ESP and Formula M threw me off.

This container says the oil meets MB 229.1 standards...tks/Cheers,

BB

Hello,

Please be sure to look at the current 223.2 spec document. I was incorrect regarding the "fact" that 229.51 is the current spec. In reality, 229.5 is the current for all cars outside Western Europe. Per the 229.5, you're looking at 0W-40 and 5W-40 as the only choices. So, technically the new ESP formula is not approved.

Just an FYI for everyone.
In all 3 of the M156's i have owned, i have always used Mobil 1- 5W40 ESP Formula M

On the C63, the last oil change, i thought i would try the Mobil 1- 5W30 ESP Formula [NOT "M"]

Both are 229.51 Approved.

Anyhow, with the 5W40 over 10,000kms i would typically have to top up about 1L (a shade of 1 Quart) give or take.

With the 5W30, i had to top up about 2 Litres (Shade over 2 Quarts) . And over the 10,000kms that i had the 5W30 in, it was EASY EASY Motorway driving. 90% Motorway LITERALLY. I dare say, if it was city driving/ harder driving i would have topped of 3L (Just over 3 Quarts)

So today, i dropped the oil, and switched back to 5W40 ESP Formula M, and will be sticking with it.

Oil temps on both are consistently 102 Deg C (215F) Water always 92Deg (197F)
Under spirited driving Oil is 112 Deg C (233F)

Would like to get oil temps down, but dont know what oil would reduce oil temp thats MB Approved.

Ambient temp usually always 20-25 Deg C (68F-77F)

Sydney- Australia.

Also, for Aussie guys looking for ESP Formula M, GL Lubricants in Revesby sell it for $11 per quart.

I filled 10 Quarts EXACTLY (dropped the sump + cooler oil)
Dropped the oil while it was at about 80Deg C

CHEAP OIL and they overnight deliver with Fastway
(im not associated with them)

They also sell PlastiDip for $17 can (unheard of on Australia- its $30 a can everywhere)

Mobil 1 esp formula M 5w40 is not 229.5 approved? Only 229.51
Mobil 1 formula M 5w40 is 229.5 approved

They are 2 different products and afaik you can only get the approved one from the dealer in the US?

Non esp approved 229.5 http://www.mobil.com/USA-English/Lub...a_M_5W-40.aspx

ESP not 229.5 approved http://www.mobil.com/USA-English/Lub...a_M_5W-40.aspx
It is 229.51 approved

rentzington

any real benefit to using 5w40M over 0w40? I know there was a big debate in another thread...i recently topped off mine with 0w40

Valvestud

Great info, but as a reminder, 5W-30 while on 229.5 is not approved for the M156.

^^^ That about cleared it up for me. Appreciate the links!

Imo no
The weight is the same at 212 f which is the operating point
The 0 is thinner at 32 f which helps at cold start-up
But in reality no difference as long as oil is changed per schedule and allowed to get hot before applying heavy loads

The dealer has put both in mine
The first few changes were 5w40
The last few 0w40

I have 0 concerns

Yanks are advised per Affalterbach edict fwiw to use no viscosity thinner than xW-40 in AMG engines, 229.5 approval notwithstanding. :nix:

Ingenieur

Not only 'yanks'
Western europe 229.5, 51, 52 0w40 or 5w40 ONLY
Rest of world 229.5 0w40 or 5w40 ONLY
30 wt is not spec'ed for the m156 anywhere

The link to the MB oil chart was posted, current as of sept 2014

Here's the chart, no debate, clear as day
http://bevo.mercedes-benz.com/d/d/en/Spec_223_2.pdf

Note for m156, western europe and RoW
2) Restriction: Only SAE 0W-40 und SAE 5W-40 engine oils are allowed !

Not sure 'edict' applies, you can do what you want
Since they designed & built the engine they spec'ed that oil based on technical considerations
Why do people think they know more than the engineers who built the thing lol

The oil not only lubricates/cools the engine, it is used as the medium in its hydraulic control systems like the cam phasors (diaphram actuator), lifters ( oriface size), etc

AMG893

This is 229.31 & 229.51 Approval
http://www.mobil.com/USA-English/Lub...ula_5W-30.aspx



This is also 229.31 & 229.51
http://www.mobil.com/USA-English/Lub...a_M_5W-40.aspx

Checked both against Mobil 1 website (see links)

I edited my post. Sorry, forgot to put the "1". My typo

AMG893

Was simply posting up my real world experience. Didint want to start another oil war thread.
Enough of that going on in the world without bringing it to the foums

http://www.ecstuning.com/Mercedes_Be...ice/ES2575992/

These are also 229.5 (NOT 229.51) approved.

Interesting BEVO pdf.
This whole time i have been putting the wrong oil (unless i lived in western europe!)
LOL
Im happy though. Car seems happy.

This is the one i will buy next time. Correct>
229.5 Approval. Correct for Australia.

Just dont like the idea of running 0W for the startup.

Ingenieur

Other than western europe, in other words the rest of the world, only 229.5 0w40 and 5w40 are approved for the m156
