Okay I have spent the better part of a week reading through old posts and surfing the interwebz trying to figure out which oil to buy. If you have an E63 (only!) I want to know which oil you buy or would buy. I don't want this to turn into another flamefest so keep it simple please. The E55 has a different requirement so that's why I am interested in the E63 owner's opinions. The choices are Mobil 1 0w40 the original recommended oil, Mobil 1 5w40 ESP, the new recommended oil or Amsoil 5w40 European car blend.

The 0w40 is the cheapest, followed by the Mobil 1 ESP and then the Amsoil, although the ESP is much harder to find. If you use a different oil please post up what it is and why. Thanks!

The Amsoil is not approved by MB, the other two are for the M156.

The 0W-40 has more wear inhibitors that the 5W-40.

MB would have you run the 5W-40 because the wear inhibitors could cause the cat to age faster which is under a mandate LoNG warrantee. Someone elsa probably knows how long. The OP should because he has researched this web site.

Motul 8100 X-CESS 5w40 or Amsoil European Car Formula 5w40. Those should be your only choices.

AMG in the Private Lounge discussed at great lengths you should never use oil that wasnt recommended by AMG/MERCEDES.

The reason Mercedes also chose Mobil1 0W40 is cause of its cold viscosity, as cold starts are what ruin motors and the tolerance of Mobil1 0W40 was one of the lowest and still provides lubrication. 5w-40 ESP was recently approved for Mercedes use because of the cat issue as stated above.

In the private lounge someone actually posted all the oils and the specific chemicals and tolerances and nothing was close to Mobil1

Has anybody here actually had a cat fail? If so they are covered for 8-10 years right? And I always thought that the manufacturer "recommendations" often times had more to do with partnerships and money as much as actual performance as the Amsoil meets or far exceeds most other oils.

Right now where I'm at (NJ) Advance Auto parts have oil change special for 5qt plus bosch filter for 30$. And I just bought 20 qt and filter for my daily. Good deal!!!

This is what I got from Mobil 1's website"

Not sure if it's a typo or not, but I have not seen 5w30 ever used elsewhere.

Just got this special promo from following Mobil1 on Facebook. Should save you a bit more

I saw that, but the participating retailers are a bunch of obscure places. No Napa, Autozone etc. Thanks though!

There also a $10 off of 5 quarts at AUTOZONE coupon. It's not a mail in renbate so u get it off at the checkout.

Pushing_Tin

heh, I saw that too, but my local autozone doesn't carry the Euro 0w40.

Mobil has had that erroneous info for some time now. We even pointed it out to the PL AMG guys, but no correction obviously.

Jon2007E63P30

You guys have posted a ton of valuable information. Encouraging those under warrantee to risk voiding that warrantee, is not one of them.

I agree that Amsoil and Motul make good products, but it would be really bad news if someone took your advice and then had an engine failure for some other non- related reason. A crate motor is some $60k.

boschk

Per the Magnuson-Moss Act passed by congress, as long as an oil meets the mfg specifications, they cannot void your warranty b/c it's not an approved brand.

Do you know that Amsoil, Motul and others do not have oils that meet the functional specifications of the oil they have approved?

Pushing_Tin

I stopped by Autozone anyway because I thought the guy I called may have been too stupid or lazy to actually look at the oil, and sure enough they had the Euro 0W40 there, so i was able to buy 10 quarts for $65.
