Correct grade 0w40 mobil oil for $37.46 case - Page 3 - PeachParts Mercedes-Benz Forum

chronometers · #31 10-09-2012, 10:53 PM

Mobil 1 0w40 meets MB229.3 and MB229.5 specs. When I put my Mercedes 1995 E300 in Mobil 1 web site's "What is the right oil and filter for my car" database, 0W40 comes back as the recommended oil.

Even though this type of oil was not available when my car was produced, I still believe it to be the best type of oil easily available to me. I like the fact I can extend oil changes to the original frequency of 7500 miles.

The fact that the price is good and the product is delivered to my door is a nice bonus:

In this link it shows that diesel engine and gasoline engines have different approved oils. BOTH gasoline engines and diesel engine are listed in the 229.3- which showed approved oils- but that does not mean all oils are approved for all engines. Nowhere does it say that nor imply it. Quite to the contrary.

So where specifically does it say that they are NOT approved for all engines? Sheet 229.3, which you linked to clearly states

Quote:

For use in vehicles/engines refer to Sheet 223.2

. That should be end of story for you. Engines that sheet 223.2 (which I gave an image of in an older post) tell you what specs are relevant for what engines. That's it.

In Sheet 223.2 from MB, shown above, it clearly states that for all other OM6xx engines, 228.x and 229.x oils are suitable for the engines. MB states the spec number and gives a viscosity vs temperature chart to guide selection. This sheet shows which MB sheet specification should be selected for all engine models that are current. The MB sheet number is all that is required to select an oil, and they can be used interchangably according to temperature.

That should be it. Period. API, ACEA, etc are governing bodies, and some manufacturers ONLY go by those. MB has long had their own sheet, and each variant has its own test criteria results that it must meet. What do you think 229.3, 229.5, etc are? Just approvals for some non-descript use?

Take a look, this is one part of exactly how Daimler specifies acceptable oils wrt the other licensing bodies. Note that there is actually NO API license requirement stated, going back to what I said above about it being third best.

And just so you can be absolutely sure that there are diesel engine tests as part of the sequence:

Again, see above in the sheet that defines oil specs for engines, and in the actual definition of ACEA and API in the approval of an MB 229 oil. It doesnt mean much.

In the document you link to for approved oils for 97 and earlier, it clearly states that

Quote:

Mecedes-Benz recommends the use of MB-approved engine oils listed in the Mercedes-Benz specification sheet 229.3 or 229.5 which also meet ACEA and/or API classifications listed below. If a MB-approved or ACEA quality engine oil is not available, then an API quality engine oil meeting the below listed API classification can be used.

They are stating here that MB approval is issue #1, and ACEA is an acceptable second. API is a distant third in how hey rank oils as acceptable. This mirrors why in the spec requirements I showed above, there is no stated requirement for any API category to be met.

Note also on the subscript on the page you linked to. ACEA and API clearly show there that they should only be criteria if 229.3 or 229.5 cannot be found. They are alternates and MB has stated which is more important.

Now, the gas engines show ACEA A3 (Gas) and B3 (diesel) as acceptable specs. The Diesel engines show only ACEA B2, B3 and B4 as acceptable. This is due to the differences in add packs for gas and diesel, and the specifics needed for the diesel. A gas can run on a diesel oil, which is why HDEOs are often called "universal" oils and typically do carry an API "S" designation. The reverse is not always true.

So that is the hierarchy. Its all here to see. MB states what sheets are acceptable, they state what oil specs should be used, and they provide their identification of the hierarchy of relevance for passenger vehicles.

But again, since when sheet 223.2 identified OM6xx engines as being allowed to run a 228.x oil, and since the 228.x oils also carry the latest API "C" ratings, this is what should be used.

What is your basis that you can extend out OCIs? Have you run UOA? IF not, then you dont have any real idea unfortunately.

I know it can be done, as Ive backed my results up with UOA. YMMV. But I also run the latest diesel additive chemistry technology, which M1 0w-40 is not. If you like M1, which is great, TDT 5w-40 would be a more suitable choice, IMO.

Thank you for posting that 2006 version of 223.2. You have succeeded in persuading me that I could safely use Mobil Delvac 1 ESP 5W-40 in my 1983 300D. Good to know, 'cause it's cheap at WallyWorld, and I'm on my last two cases of Mobil 1 0W-40.

Yeah Ive advocated the latest APC "C" oils for the MB IDI engines since I started with MB diesels back in 02. Why not have the latest diesel-specific oil technology?

My 300D only sees about 4-5,000 miles a year at the present time, mostly all city driving. I have been using Mobil 1 0-40 and was just getting ready to buy more from Costco with their $10 off per case this weekend, but this thread has me wondering now. What are you guys using in a car that doesn't get driven a lot?

JHZR2 · #37 10-10-2012, 09:43 PM

Honestly for that I would just run Delo 400. Youre in tuscon, so the cold start issue is a bit less prominent, and given the power output, I dont see oxidation of a good Group II+ basestock of an HDEO like that to be an issue at 4-5k miles.

Im a huge syn advocate, and personally run syn in all our 7 cars, including our w123 cars (Rotella and Schaeffer's syns, 5w-40), but your use profile just doesnt really fit. Even on my low-mileage 240D, I extend OCI to three years, based upon used oil analysis.

If youre set on syn (I wont argue!), Id run M1 TDT 5w-40 or else Rotella Synthetic 5w-40.
