I want to personally thank you guys for your input thus far...I am still kind of confused but still leaning more to the cheaper Mobil1 which my local MB dealer said 5W40 is the current version used for MBs instead of 0W40...but I may try RP once to see if engine runs smoother not for the HP claims.

Gentlemen:
The BIG debate is/was that Mobil 1 reduced their phosphorous levels, in PPM. Note: This was a US LAW requirement so ALL oils sold in the US now have this reduced phosphorous level due to the requirment of Catalitic convertors clogging on HIGH levels. Anyway, ALL oils have been reduced that are sold in the US. Run whatever synthetic you like, I have been using Mobil 1 for over 20 years now, and my ex crew chief worked at a local research comapany, OIL research that is. After all his tests, Mobil 1 was JUST as good, or better than ALL the other brands. Did I mention that it is ALOT cheaper
Oh yeah, some other brands were a tad better in high temperature breakdown issues, however we are talking about 5 degrees here. REAL world results NO DIFFERENCE, IE 535 vs 540 farenheit.
Oh well, I will be staying with Mobil 1, suit yourself, after all its your money.
See yeah

I've run Mobil 1 for 20 years and something like a 400,000 total miles without a single oil-related problem. When I did the timing chain on my M5, a more highly tuned engine than a big lazy AMG C55 V-8, it looked virtually brand new up top and in the crankcase at 165,000 miles.

For me the biggest difference is that if I frag the motor on my CPO car I don't have to worry about proving to MB that a non-approved weight or type of oil didn't cause it.

Guys I use RP with NO PROBLEMS on my C55. You need to look at sm and sl rated oils. If you look mobile still has the good stuff but its bottled under 40W diesel app. I used Rp and have no ticking at all. With mobile1 I had a ticking at idle. Please read up on this.

When
you gall a cam or spin a bearing then tell us about you had no problems with the RP in your c55,better yet like I always say have the nads to put in the ad when you sell the car someday. That you always maintained it with non spec,non mb rated non 229.5 non approved oil.I always look over the ads when searching out cars for forum members and it is funny how when it comes to maintaining mb's the owners all seem to have used factory spec mobil1 0w40 even though members like you don't and think that's okay.If your engine was ticking it was not the mobil 1 that did it,it was poor maintenance.
So please come selling day tell everyone up front what oil you used,that way they can make an informed decision whether to purchase your car or not.
do you see RP?
http://www.whnet.com/4x4/oil.html
if you call them they will tell you it is not approved 229.3 or 229.5
and you trust that jewel of an engine to it?
I bet you run k/n filters and a sprintbooster also.

AMSOIL is not on that list either, and it has been independently verified as the best synthetic for overall wear protection. Just curious as to what is wrong with either K&N filters or the Sprint Booster? The filters offer superior air flow, and yes I am full aware of the MAF issues, which are caused not by the filters themselves but instead by the owners over oiling them after 50K miles. The Sprint Booster is a bad choice because it improves throttle response and virtually eliminates the downshift delay? C'mon my friend, just because it isn't "MB approved" does not in any way automatically mean the product itself is detrimental. In all fairness, there is a ton of garbage out there...but some exceptional products exist as well.

The 0W-40 Mobil 1 meets 229.5, the latest gasoline-spec oil, and it is one of very few (perhaps the only) 229.5 oil approved for AMG. 229.X oils are gasoline rated (vs.above.)
I have done a lot of research on motor oil, and have considered switching to RedLine and RP many times, but the fact remains that they do not meet any MB spec. If these companies do not care to meet the standard or apply for the rating, they do not deserve my business, not to mention, it would void any warranty.

Please know what you are doing before making comments
You forgot that I have BBS wheels and coilovers too
Before you make comments such as the ones you make please read up on the matter.
The reason why mobil reformulated thier oils is to spare the cats on our cars the bad side it will toast your motor over time. you see the new oils have less phosphorus along with a bunch of vital components needs to keep things in check.

If you do go to this oil please change it every 4500 miles or so. Guys this is not the oil you used to think you had. I used royal purple 10w40 and it works great. If you want to stay with mobil then try the 10w40 diesle its still a sl rated oil.
So when i sell my car i will give them this to read.

Clearly, there are oil formulations that are approved by MB and some that are not. Strategic business relationships between disparate companies often play an important role in what oils are 'recommended' by an auto manufacturer.
That said, oil formulations should be (and ARE) tested empirically by the likes of MB, etc.
The question to ask here should be directed to those who track/flog their cars and those who have significant mileage on their cars.
Of course, one variable not being addressed here is the frequency at which oil changes are performed. Another important thing to consider is that very few motor 'tear-downs' have been conducted (or at least they aren't reported on MBWorld!).
Assuming 'non-trackers' change their oil every 3-7K miles and 'trackers' change it more frequently, how are your motors holding up? Let's ask M112K owners with high mileage (e.g. 90+-150+K miles).
What does your oil look like when you change it? (Not particularly scientific, but color and odor are sometimes useful). Any evidence of aberrant metal particles?
Who goes to the trouble of analyzing waste oil upon changing? This is expensive and arguably not necessary; however, if I were going to switch to a brand of oil that were not necessarily 'recommended' by MBZ, I (personally) would analyze it for the first couple of changes.

Define for me: "More highly tuned." Are you saying that the C55 engine is put out in a less tuned (i.e. lower state of tune?) than the M5?? Big Lazy C55 V-8??? Define for me a "Big Lazy engine??"

This sucks
I just found out that the oil extractor I ordered from Harbor Freight is on backorder...Why can't the site say so when the order was placed I only got an invoice number and thats it. Anyone in the Chitown area has an oil extractor I can use once? I still have to buy the oil filter so I have time.

Watched the "Royal Purple Challenge" performed right in front of me ON A DYNO. Guy from Katech (GM modding place in Detroit) was on with a Caddy putting down 423whp. That was before Royal purple, they swapped out the oil and dyno'd it.......car lost 1hp.
After sitting around wondering what the heck happened we came to the conclusion that swapping synthetic to RP gains near nothing while I bet going from regular oil to Royal Purple gives the gains they brag about.
Pretty cool watching it happen right in front of you.
I would say no to on going Mobil 1 to RP.
