There are some MB229.5 that are not "approved" by AMG (but okay in other MB motors) http://www.whnet.com/4x4/oil.html
Mercedes only recommends M1. Under warranty you need to use a MB229.5 oil. But sure, if you want to be 'safe' then use what they say to use.
Besides 229.5, the only other thing MB requires with AMG motors is that you use the correct viscosity.
btw, here's what Mobil says about mixing oils:
"Mobil 1 is fully compatible with conventional motor oils, semi-synthetic motor oils and other synthetic motor oils, should it be necessary to mix them. However, it is important to note that the superior performance of Mobil 1 will be reduced by diluting it in any way.'
Every oil mfg say the same thing: "superior performance will be reduced." Primarily because they don't want you using other brands and they have to keep within their own liability parameters.
As far as ESP or not ESP, ESP is a MB229.31 and 229.51 oil which is required by MB for their diesel engines. That has primarily to do with ash content (for particulate reduction.) But it still falls under 'approved' and is not (yet) listed as "unapproved" for AMG motors. I think MB dealers started using ESP to cover all their bases as it is also approved for gasoline engines.
But some say that it has reduced additives. Check the bobtheoilguy.com forums. Most dealers will (should) have both. The dealer here uses M1 and ESP, but I'm guessing a lot of dealers might want to save some $$ and will just stock ESP.
I guess if one is really concerned, then just use reg M1 or Amsoil for peace of mind.
edit: p.s., I just noticed you drive a 2001 E320. I wasn't paying attention. Anyway, you aren't held to using 229.5 and can also use 229.3 which gives you a lot of choices (see link above)

Is the 0w-40 that is sold in stores (in the US) the same as the 0w-40 used in dealerships?
I just called a bunch of dealerships and the Mobil 1 they use varied from 5w-30, 5w-40 to 0w-40.
The Best of Mercedes & AMG

I note that Valvoline offers a 100,000 warranty if you switch to them before you hit the 40,000 mark, but I have no idea if this is worthwhile. I also note that some other segments of the high-performance segment swear by Royal Purple synthetic - but I don't see it in the chart.
I was asking about the break in oil as I'm researching how to best break this car in. Synthetic oil from the factory is probably too slippery for the piston rings to seat properly. Has anyone replaced the factory fill with a break in oil such as Valvoline 30W for the first 500 miles or so, then switched back to a synthetic?
If you track it, it's a different story.

M1 0w/40 is 229.5 MB approved. Best I can tell M1 doesn't have a 5w/40.
So you can use any oil as long as it is one of the two weights above and 229.5 approved.

fwiw, doing a UOA will give you the info you need and peace of mind. It's not expensive. When I used to track my cars (not MBs) oil quality was imperative esp with air cooled dry sump motors (theoretically 'oil cooled' motors.)
Here's some info from someone with whom I have had personal experience. Although it's Porsche-centric, it's still a worthwhile read (and also someone who can do your UOA for you) He is a Northwestern grad engineer and well-known in Porsche motorsports. (LN Engineering mfgs custom cylinders, rods, and pistons all in-house.)

I wondering what my dealership has been using in my AMG since they have been telling me they were using 5w40. Then again, I've only had 1 oil change in a year.
So bottom line is, use the M1 0w40?
