Why you dont want to wait 10k miles for your first oil change...
I dont understand why MB insists that you dont need to change the factory break in oil at 1k miles (dont even get me started on the 10k oil change intervals).
If anyone thinks or believes MB when they say an oil change after break in is not necessary check out the pics below.
I just changed my oil after 1112 miles on the odometer, below are pics of a sample of the oil that came out.
All those little sparkle things are tiny specs of metal that are a by product of the break in process, and your oil is full of it after you have broken in your car. You defiantly dont want all those metal particles circulating in your engine for 10k miles.

This has NOTHING to do with the dealer. It has to do with the mfg, aka Daimler AG. Changing the oil less often has nothing to do with the dealer screwing you over.
3-4k OCIs and you are throwing money down the drain and screwing the environment.
People need to study up about oil. One more time to the OP: why don't you do a UOA? It's inexpensive and it will tell you what's going on for certain. Now is a good opportunity to find out.
ps, the shavings are normal, of course. The filter oil will have tons. I do change break-in oil earlier than mfgs recommended and filter, too. Here's a random Blackstone report attached as a .pdf.
I did them (UOAs) every time I changed oil (on my P-car) for a couple of years just to learn the best intervals and what really was happening with my oil.

Although my C63 is still brand new, I have done 4 UOA's on M1 0w-40 in an E39 M5. Without getting into specifics other than to say that the performance fell into the "very good=good enough" category re. wear metals, my recommendations based on those UOA's are:
If your engine consumes little oil between changes, change oil and filter at 6K miles.
If you need say, 3 qts of makeup oil over a 6K miles period, feel free to stretch it out a little, to 8K miles. Do not go the full 10K, though, as I have done it once and did not like the results of that UOA (remember, in a different engine).
IMHO.

ps what were the results you "didn't like" ? Did the TBN drop that low from the original? Or what else?

A UOA after oil has been in an engine for 1k miles will obviously tell you that the oil is still fine...thats not the point I am trying to make. Its the fact that those metal particles are circulating in your engine and can cause damage if left in there for 10k miles like MB recommends.

I dont need to do a UOA on the first oil change because I know whats going on. Compare the oil in my pictures to any oil change after the initial break in and you wont find the oil filled with metal particles like that.

fwiw, I changed my oil just about at 1k because the build date was last summer '08. The car (2009 E63) was sitting on the dealer's lot for almost a year (bought it in late May '09) But my oil didn't look like that. I also didn't bother with a UOA because I knew the TBN would be okay. But I didn't have that kind of obvious visible metal content. I didn't cut up the filter to look, either.
I'm doing another change this weekend (with about 2.5k) and then will go into my usual OCI from that point on.
I'm confused with that(?) What are you saying? That your particles are excessive? That any oil change after 1k won't have the amount that your oil has? Or do you really mean a change at 10K+(?) I don't follow.

When you did the oil change, and I assume you personally did the oil change yourself, what did the oil filter look like? How come the filter didn't catch all these particles. Apparently the filter is doing its job, and the size of the particles do not appear to be a factor, as you put it, circulating through the engine!
Well, maybe those krauts don't know what the hell they're doing after all and only have half the smarts we give them credit for. I sure like the way my car drives and handles. Good luck with the particles.........
