quote:The page you got this from needs to be updated. MB is putting Mobil 1 0w40 in some of its non-AMG models. Example: in a recent road test I saw of the S600 (twin turbo V12), the Mobil 1 sticker was clearly visible under the hood in the photo of the engine bay. The AMG engines are MB's "cream of the crop" top performance engines. They are hand assembled in their own section of the plant and every single one of them gets Mobil 1 0w40 as the factory fill. Commons sense would dictate that MB is going to put what it considers to be the "best" oil available in those engines.
Originally posted by pscholte: Depending on the model, M-B (not AMG models) first fills are: Aral SuperTronic M Elf Excellium 229.5 5W30 Fuchs Titan Supersyn SL MB HiTec Sythetic Motorenöl (DC itself) Mobil SHC Formula MB Motorex Profil M-XL Shell Helix Ultra AB Shell Helix Ultra DC 229.5 Total Quartz 229.5 5W30 Many of these are especially for MB and notice Mobil 1 is not among them
quote:What does it mean? It means nothing more than these oils are not DESIGNED to meet those specs. The base line for MB 229.3 and 229.5 is ACEA A3. All Mobil 1 Xw30 oils are designed to be A5 oils, and that's a bandwagaon that MB hasn't jumped on yet. But with the exception of the HT/HS requirements, A5 is just as tough a spec as A3.

quote:ACEA A2-96 is a 1996 spec and the lowest spec of the lot. ACEA A1-02 is a higher spec is some regards. Here's more info from ACEA: Gasoline Sequences A1--Oil intended for use in gasoline engines specifically designed to be capable of using low friction, low viscosity oils with a High Temperature / High Shear Rate Viscosity of 2.6 to 3.5 mPa.s. These oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt. A2--General purpose oil intended for use in most gasoline engines with normal drain intervals, although it may not be suitable for some high performance engines. A3--Stable, stay-in-grade oil intended for use in high performance gasoline engines and / or for extended drain intervals where specified by the engine manufacturer, and / or for year-round use of low viscosity oils, and/or for severe operating conditions as defined by the engine manufacturer. A4--Reserved for future use for gasoline direct injection engines. A5--Stable, stay-in-grade oil intended for use at extended drain intervals in high performance gasoline engines designed to be capable of using low friction, low viscosity oils with a HT/HS of 2.9 to 3.5 mPa.s. These oils may be unsuitable for use in some engines. Consult owner manual or handbook if in doubt. --end quote-- So, European oils are made more expensively to a higher spec when needed, A5 is the tough energy conserving spec, A3 is the toughest spec, and Mobil 1 0W-40 and 15W-40 are different formulations than the Mobil 1 xW-30 line of oils, not just different viscosities. Roughly speaking, ACEA A2-96 oil probably compares to the lowest quality API-SL oil on our shelves, with ACEA A1-02 comparing to API-SL "energy conserving" oil. Ken

I was browsing the shelves of the local Super Wal-Mart in Landau, Germany, just last week and I was amazed that even their cheapy oils were at least ACEA A2 rated. Wally sold a 5 liter container of 15W-40 for 5.89 euro and also offered the full line of Pentosin oils and even had the STP oil treatment (made in the UK though). ....

quote:My last 3 Mercedes have decreased in quality and reliability. My last ( 1997 factory order ) had to have the following items replaced under waranty in the first 4 years. Power steering box. Front crank oil seal ( 4 times till they got it to stop leaking ) All oil seals in rear end. Climate controll computer. Auto trans valve body ( 3 times under waranty ) The trans finally blew up at 60,000 miles and needed replacing out of waranty. The rear end started wining. Now ten years ago, Mercedes would have looked after these sort of problems with great concern. Today they don't rally care and never batted an eyelid when they quoted me $4,700 for the transmission. I use Mobil 1 0w-40 in my new car because I like it , not because Mercedes gets it from Mobil cheap.

Just my humble opinion.
quote:I couldn't agree more on that. All the problems with my car (Audi A4), were caused by poor or incompetent maintenance by a dealer/independent shop. Ever since I've been doing this stuff myself, I haven't had any problems. That incudes fixing the stuff the dealer and independent mechanic couldn't (or didn't want to) fix.
I think you need a new garage/mechanic...and I've seen all kinds of garbage work out there....dealer or otherwise.
