Oil Consumption Question
My 09 seems to be burning about 1.5qts every 1000 miles or so. It has about 19,000 miles on it. I took into the dealer today to top off because I was getting the check oil warning, and the SA seemed to think that it was burning a bit more oil than normal. He said he would like to do what he called a "consumption test" where they top off the oil and run the car for 60 miles and measure how much oil is burned. He claimed that if it was below a certain level there is a serious issue with the engine and that more than likely it would be replaced under warranty.
Has anyone ever heard of this?
If the engine is replaced does anyone know if this would have a negative effect on my resale value?

How hard are you driving it? I'd say most of us keep bottles of oil handy to dump in there every now and then but 1.5qt every 1k is a lot imo.

Does seem a little high especially as at 19000miles the motor should be fully run in.
Sounds like the dealer is working with you on this which is a good thing (though I would question the accuracy of their consumption test after just 60 miles of driving).

This is a normal procedure that the dealership does, to evaluate oil consumption. This will tell them, whether there's an issue or not.

AMG has stated that it's not uncommon for their engines to burn 1qt for every 1000 miles. 
Porsche's are worse than us. 
But 1.5 qts is a bit much, I think. Both my C63 and E63 use about 1/2 - 3/4 qt between oil changes, so I'm very fortunate. I just added 1/2 qt to my C63 last week, and I'm due for a oil service in 1700 miles.

I had a similar problem where my oil light came on 1500 miles after getting an oil change done. They topped it off and the oil light came on again a month later (about 1000 miles) and so i took it into service and turns out the oil sensor that read the oil level went bad, so they replaced it under warranty. Maybe thats what could be happening here?

So after two consumption tests (because the dealership did not have the MB certified measuring tool for the first test) it was determined that my car burns ALOT of oil. For the 600 miles it burned 2 quarts of oil. So the dealership has been authorized to replace pistons and bearings. Do you guys think I should be worried? I also asked to see if they might give me a extra year on the warranty. I know its a long shot but I thought I would give it a try.
Thanks for the advice!

Now your car is 1 engine 2 men lol. Doesnt that go against AMGs philosophy?
I'd say F that and ask them for a brand new complete bottom end from the factory...
You really want some mb techs rebuilding your engine that are used to doing everyday maintainence?

Get it fixed right the first time! New complete bottom end from factory or a new engine.

Yeah that is what I tried and the dealership was turned down by MB. The SA said the cylinder walls were fine and MB would not authorize the short block to be replaced. Also it was my understanding they would need to stamp a new block to match my VIN so that would take time I guess. I just came back from the dealership and saw my car in pieces so I am freaking out a bit!

If the cylinder walls are fine why is it burning oil then?? Why didn't the rings seal properly the first time the engine was assembled??
at 19,000 miles the cylinder hone may look good to the naked eye, but its worn down. Both the cylinder and rings wear into each other during beak in. How is this supposed to happen if the cylinders are already worn down?
The idea behind the hone is it creates an abrasive surface that wears smooth as the rings come in contact with it. The rings I believe are tapered so that they also wear nice and flat against the cylinder wall.
Without a good ring/cylinder seal, blow by creates excessive pressure in the block which pumps more oil into your intake to be burned off. Also, excessive oil is left on the cylinder walls being burned off too.
I'd drive the **** out of it as soon as you get it back. Break it in nice and hard. If that doesn't work, new engine time.

My thoughts exactly, if you are trying to sell this car private and the buyer does service history at a dealer.. This info would be a dealer breaker for most buyers.. Unless you plan on trading this car into the dealer or its a lease return.

Lol i keep a quart of oil in my trunk all the time just in case since they do tend to consume a lot of oil i heard it gets better with time, though 1 quart per 1000 miles is a lot unless you tracked for 500 out of 1000 miles. My car puffs blue smoke on startups some days and some days it doesnt. Runs like a champ though.

Well, only knowing what's written here, I wouldn't be happy with pistons , rings & bearings either....particularly on such an expensive engine. BUT, if that's all M.B. will do...well, they'd be a big company to argue against wouldn't they?
So, what does the Dealer say is wrong, why is it using oil, are the rings worn, is the bore glazed, are there any marks in the bore, what has caused the problem?
If the O.P. could be supplied with answers to these sorts of questions, then maybe he would be better placed to know whether what M.B. is offereing will do the job.
What sort of relationship do you have with the Service Manager?...Do you think he's "on your side" & looking after you?
I must say, that at this stage, a new set of pistons, in simply a honed bore, does seem a little "light on" for this type of engine?
But maybe a good chat with your service manager can ease your concerns.
Cheers, Pickles.

DKubicki: Can you update us on this thread as things progress with your car and what they are doing to fix it, etc..
Im interested to see what comes out of this and how MB handles this.. AND if replacing these parts is going to ultimately be the answer to your oil consumption. Thanks
