High Oil Consumption (0W40 Mobil 1)
After EC installed my headers at the end of August, I got the check engine oil at next fillup message three times. I just topped off oil for the third time today.
1st time (+ 1L):
Beginning of September, a few days after headers. I chalked it up to the dyno run burning a lot of oil. Bought another jug of M1 0w40 and added about a litre, checked dipstick and it was at correct level.
2nd time (+ 1L)
Last weekend. I drove the car quite a bit from 1st to 2nd top up (probably 2000-3000 km in mostly Manual shifting), so I added a bit less than a litre but didnt check the dipstick level. Perhaps it wasnt topped up?
3rd time (+ 1L)
This morning. Not that much driving from 2nd top-up to today. Maybe 500km. Topped up and dipstick is now at correct level.
It feels like my 4.5L M1 Jug has about 1/3rd left. So in total, my car has consumed about 2-3 litres of oil to run the last 3000-4000km. Yes, i've been driving the crap out of my car this summer and after the headers install. The car and exhaust sound is intoxicating. Most of the mileage was city driving in manual mode, so revs were definitely a bit higher than if it was in one of the auto modes. Should I be worried? Anything to check?

How many miles on the car? If you have been driving hard, I wouldn’t worry. I needed new valve stem seals at 85k though.

That doesn't sound normal... Have you had a compression/leak down test done?
I had bad oil consumption issues in my PFL C63 and would have a puff of smoke appear during start up after sitting for a few hours. Are you seeing any smoke during startup? Check for leaky gaskets anywhere? I would assume a leak that drastic would show signs pretty easily.

I'll pay some attention to any smoke during startup. I do not recall any.

I know everybody's oil consumption varies, but I haven't ever had to top up this motor between oil changes.
Ton of city/urban driving, all done like I was a 15 year old who just escaped from Juvenile Custody.

It sounds okay, some other members reported about 1 quart per 1000 miles. Im a bit closer to 1 quart 600 miles, especially in September but its stop-go traffic and occasional highway pulls, so maybe the consumption is worse because of this? First three months I had the car was no issue.

Start with the leak down/compression tests and go from there. A visual inspection of the undercarriage wouldn't hurt either as you said you didn't seem to have this problem before the header install... Although I'm not sure how that would have any dramatic effect on consumption.

Is it ok to drive it until the message comes on again? I would like to gather some more evidence and allow a bit more time before spending $$ to hunt down problems... sigh..

From checking my own car log:
I put in 9L of Mobil 1 0W40 in early July (with filter of course)
Headers installed end of August (74xxxkm)
In between the above Install and now, I've had to top off oil three times. The first 5000km I got the car, I had no oil messages. Is there anything about the headers install process or not running the stock manifold/cats/exhaust that can mess with oil consumption?
Just started my car and didn't see any smoke or anything. I've never noticed any on my car and my girlfriend usually rides with me to work, so when I cold start the engine, and she didn't notice any either.
My spark plugs are due for replacement. I don't see how that can affect oil consumption?
Also, just saw a post that gives me a ton of hope:
Engine braking will generally yield higher oil consumption. Id bet that the guys who are burning more oil than others engine brake more than the guys who burn less. My M5 was the same way. Engine braking every opportunity i got netted me a liter of 10w60 every 800kms.. dropped engine braking and i could go about 4-5000K per liter. Mine just loved oil.
Rebuilding engines at a dealership level is not overly common anymore. At the end of the day Warranty will be paying atleast 15 hours to pull the motor and strip it to a short block state. At that point there, it will either go one of two ways, it requires a motor or will require more labour to dissassemble and repair. Even in that case they throw pistons in it, still burns oil, now they have to eat the 20+ hours of labour plus they end up putting a short block in it + labour anyways. This is true for non hand-built engines.
I am personally surprised, i would have figured being an AMG hand built engine they would have a AMG head tech fly down there to do the tear down and inspect. Or at a minimum call for a short block. Personally i wouldnt be happy with anything less than a short block BUT at the end of the day the money is not coming out of your pocket and if it fixes it then its hard to complain really.
Rebuilding a motor isnt for the average DIY. But at the end of the day, this engine isnt something from 100 years in the future, it still follows the same principles as your traditional overhead cam chain driven motor. Sure clearences will be tighter and technology has changed with regard to variable valve timing. But some of you guys are making these things sound like something from nasa. I dont know about your techs in the states, but a 2nd year apprentice in Canada would be "certified' to rebuild your average motor.
Anyways good luck to the OP hopefully it fixed your problem. I am curious to the outcome. If the walls werent scored and they werent out of round, then its very likely the rings were the cause. Was there any mention of the valve stem seals being replaced?

Just some feedback, I used to believe in this. Mine would burned about a quart every 2-3k. Then one day, I decided to check out the plugs and presented my findings to the dealer. Story short, Mercedes replaced my bottom end (thank god for extended warranty). Havent burn anything to the extend of oil warning light since (regardless of 5/40 or 0/40). Though consumption for 0/40 is more (I change my oil every 8K)

My car would puff smoke when taking off from a stop sometimes (not that often) and it drank some oil. I can’t remember the rate which it drank oil but it wasn’t terrible. I had the seal replaced when the heads were off for headbolt replacement. They inspected the heads and found the seals worn.

I pretty much drive in manual all the time, with lots of spirited driving.
And I don't use anywhere near as much oil as you are using. Something doesn't seem quite right.

My oil consumption at 5-6k miles usage:
M1 0W-40 - 4 qts
Motul 8100 Xcess 5W-40 - 1/2 qt
M1 is widely regarded in the enthusiast automotive world as an excellent oil that frequently results in high consumption rates. If that bothers you then try a 5W-40. Little chance that something is suddenly wrong with your motor(s).

Awesome. I did a lot of searching and it seems my consumption is high but still reasonable for my driving!

i have 117k and don't burn any oil...been using Motul Xcess 8100 5w-40 with LiquiMoly MoS2.
when i ran Mobil 1 0w-40 my car would leak oil out of the engine at various points. maybe even consume oil...not sure honestly, but it wasn't fun. probably due to the 0 weight. With Motul much less, very little actually until those seals blew out entirely.

You might just have a valve cover gasket leak...it's not uncommon and can go un-noticed because of the under tray, but moreso because little drips might just get burned off by dropping onto your headers, hence why there isn't much evidence of a leak on the ground.

Notaballer,for what it's worth, backin 2002 -2003 when I drove a Corvette Z06, with about the same size engine as we have in our C63s, the forum members who ran higher rpm like you apparently do seemed to all complain about high oil consumption in the 600 to 1000 miles (not km) per quart range.
GM at the time insisted this was "not a problem".
On the other hand, my own Z06, which I drove like I drive my C63 - pretty conservatively MOST of the time, didn't need any oil at all between 3000 mile oil changes.
Your oil consumption might just be normal for a C63 being revved high and engine braked (to hear that wonderful exhaust sound on decel that you apparently love).

The engine sound is simply addicting!! Never fails to put a huge smile on my face and initiate a complaint from my girlfriend, when shes in the car
