Recall cls 63
O.k took my 63 in for the "A" service. The service writer said there is a v belt recall. I also asked to see the service records. Well looks like my car has been in twice before. The tech states that there is excesive oil usage on both visits, once at 4900 mile and again at 7600 miles, now with 9100 miles I have the same problem with the oil being used. I told them, three times in for oil usage sound like a major problem. As always the techs state that the 63's will use one quart of oil every 1000 mile.. WTF? I own a used car dealership and if I sold a car that used a quart of oil every 1000 miles a full refund would be in hand. I smell a LEMON LAW brewing.. any in put ?

So maybe you just need to beat on the car a bit to make it seal. The shop foreman did say that the ultra hard metal used to line the pistons in the new generation of engines takes quite some time to break in and seal. There is a TSB for this issue on the new V6 and V8's. Maybe the AMG motor is similar.
If compression is spot on and the car makes power I think its just a matter of time until it goes away.

My M5 burns at least that. High revs break down oil like crazy. Plus it uses a very special lightweight oil that doesn't like the abuse. What kind of oil are you putting in that thing? Mine takes 10w60.

thanks for the wisdom "tranferred" but what does that have to do with this topic 
but thanks any how.. Guys, thanks for the helpful input. I will keep an I on the oil. The car has 9100 mile on it. I would think it is broken in. So looks like I will beat on the car for the next 1000 mile to see how it does...

Off Topic
If you truly have 1969 Porsche 911 RS you would know that every 500 miles you must add 1 quart of oil. That is what the factory clearly states is normal in the owners manual. Aditionaly that is for an engine that is broken in.
My Berg-spyder 2.2 twin plug, slide throttles, MFI will easly burn 1 quart in one round trip Avon CO. to Aspen via Leadville @7000 rpm.

Get a load on that engine

You just have some glazed cylinders
We run in our aircraft engines @ 90% load, real hard to do in an E 63 in the USA.
Reprint from Textron Lycoming
For those who still think that running the engine hard during break-in falls into the category of cruel and unusual punishment, there is one more argument for high power settings during engine break-in. The use of low power settings does not expand the piston rings enough, and a film of oil is left on the cylinder walls. The high temperatures in the combustion chamber will oxidize this oil film so that it creates a condition commonly known as glazing of the cylinder walls. When this happens, the ring break-in process stops, and excessive oil consumption frequently occurs. The bad news is that extensive glazing can only be corrected by removing the cylinders and re honing the walls. An expense that can be avoided by proper break in procedures.
Now I don't know if our rings are pressure back or not, but if they are you must load the engine to make them seal/seat.

I don't follow your reasoning that that would prevent glazing, if anything it helps to promote it. I am not trying to be confrontational. I am sure that larger Mercedes dealerships have bore scopes to assess cylinder wall damage. That is the only way to tell what is going on plain and simple.

All V8 Mercedes for the past 30 years have had a "special silicon coating ".

This is brand new technology in the 63 engine my friend.
Unique process for cylinder wall coating
The engine block and cylinder heads are of cast aluminium-silicon alloys (AlSi7 and AlSi17) which represent the state of the art in terms of weight, thermal and mechanical resistance and long-term strength. The engine specialists at Mercedes-AMG use a particularly advanced process for the eight cylinder walls to produce a tribologically optimal surface, namely a coating applied by twin wire arc spraying (TWAS). The advantages of this technology are extremely low friction and wear accompanied by outstanding long-term durability. A considerably harder surface is achieved compared to conventionally coated cylinder walls. In fact the cylinder walls of the new AMG V8 engine are twice as hard as conventional cast iron liners – a quantum leap for engine specialists.
No other series-production engine apart from the new AMG 6.3-litre V8 unit can boast such sophisticated technology - which means that once again, Mercedes-AMG has underlined its pioneering role in the development and production of innovative high-performance engines.
During the TWAS process, two metallic wires and an atomising gas are brought together in a coating unit. Passing a high voltage through the tips of the wires breaks the gas molecules down to form a plasma, and the wire tips begin to melt. The atomising gas removes molten metal from the wire tips and sprays these particles onto the cylinder walls to be coated, where they solidify. This is preceded by a high-pressure water jet which roughens the cylinder walls so that the individual sprayed particles adhere to the surface during the TWAS coating process.
The cylinder walls are then honed to achieve a perfect surface structure. During this process the micro-pores in the sprayed coating are partially exposed, which enables them to retain oil when the engine is running and ensure tribologically favourable lubrication of the pistons and piston rings.
This trailblazing process was developed in close collaboration between the DaimlerChrysler process engineering department and Mercedes-AMG, and has been brought to series production maturity for the first time in the AMG V8 engine.

What the article states 1.>>>"micro-pores in the sprayed coating are partially exposed, which enables them to retain oil "<<< this condition helps promote glazing. 2. >>>"The advantages of this technology are extremely low friction and wear "<<< the improved coating provides low friction, this too is conducive to glazing, and further prevents piston rings to run in.
Additionally the oil that is retained on and in the cylinder wall will oxidize on power stroke this is the first condition of glazing.
Once this condition starts the piston rings may never seat/seal properly. The engine will still make power, idle smooth and seem to be problem free. The reality is that oil consumption will be excessive as will be the contamination of that oil, (black oil) you may also experience larger amounts of crankcases blowby and fouling of the cats.
Hey this is just an educated guess seems more than one 63 is using more oil than any of us expected. If you have a better explanation, have at it. Further more if you have a 63 time to use that dip stick every 100 miles and start your log.

2010 RRS ; BMW K1200R; 14 E350 ; 14 RRS on order
I just added a quart to mine at ~ 4000 miles and it had an oil change at 1200. So somehow between 1200 and 4000 I burnt 1 quart. And let me tell you, I didn't break this engine in at all. I drove it like an AMG from day one.
Another thing to consider is that the W0-40 oil is a high performance oil ... don't know what that means exactly but it might be a factor.
Personally I don't mind having to add some oil from time to time to the car. I like being in the habit of checking it anyway.

Thank you for taking the time to post the article. Mercedes has been running aluminum bores that have specialized coatings for years. Now if you can explain how this prevents glazing, I am all ears.

Sounds like this 63 is going to be one bullet proof engine, as hard as it is to break in.

I had oil problems...burned quite a bit...they did some fixing and I haven't had any problems since...knock on wood...said it was due to the fact that the engine was hand built and things just needed to be tightened a bit more...
