Has MB changed recommendation from MB1 0w-40 to 5w-40 for w210 2001?
I bought my 1rst MB (2001 E320) in Jan 07. It has done about 5K miles since last oil change. I would like to continue to change at 5K intervals. I have searched these and other forums and most everyone says to use Mobil1 0W-40. Mobile website suggests the same for this car. Only few here and there on the forums recommend 5W-40. One person stated that his dealer used 5W-40 and told him they used to use 0W-40 but changed to 5W-40 due to a new bulletin they received from MB.
I just called a dealer near me and they said the same thing. They now use 5W-40 for this car. They said if I want 0W-40 they can put it, but they recommend 5W-40.
Has anyone heard of this new bulletin change from MB? What is the difference between the 2 grades of oil? What grade should I use?
I appreciate your input.
I also called another dealer, and he confirmed. He said they used 0W-40 on AMG only, and the rest they use 5W-40 for 1998 or later models.
Is there much difference between them? Would there be much differece in the gas mileage? I currently do about 20-21, but most of my driving is in city.
The new oil addressed by the service bulletin is dealer-only. It's the low-SAPS oil mandatory for the new diesels...it's not Delvac 1 or equivalent. This is a brand-new product prepared for MBz. i don't think it is certified against any other OE specs. Again, dealer-only.

Are you saying this is a different oil than the 5w-40 available at most stores (wal-mart, autozone ...etc, which is set for turbo diesel engines), and is only available at dealer shops?
If so, I am not sure what marketing strategy Mobile1 has, but losing the market with other oil change shops makes it hard to understand why "dealer only"?
I think I found the answer; those are 2 different oils and are described here:
Mobil 1 Turbo Diesel Truck 5W-40 is here http://www.mobil.com/USA-English/Lub...ruck_5W-40.asp
Mobil 1 ESP Formula M 5W-40 is here http://www.mobil.com/USA-English/Lub...la_M_5W-40.asp
I just hope the new one will be available at stores, and won't be limited to dealerships.
Thanks again.

The API oils have a high level of additization and that ultimately would poison the exhaust after-treatment devices of the newest cars. That's why the new product is labeled low-SAPS indicating it will work with the BLUETEC vehicles.
In general, the API specs and the Euro oil specs are mutually exclusive. Proper MBz oils carry a 229.xx designation.

MBz seeks to have only one bulk oil and this is the direction they've taken. This newest oil is NOT required in earlier cars whether gas or diesel.

Can any one tell me the recommended oil to be used for 1996 E320 with 130,000 Km on it? I live in Montreal, Canada where the general concept is to use different kind of oils in winter and summer. I am more interested to use some synthetic oil but I read a lot of problems occuring while switiching from conventional to synthetic oil. Can any one help me figure out this problem. Thanks
Nobody here will know if you are going to suffer leaks when making the change from petro-based oil to syn oils.
229.51 indicates low-SAPS suitable for use in diesels with specialized exhaust after-treatment. It will also be applied to the gas engines.
I don't know what kind of car you have and won't comment on its oil requirement.
There's no reason folks can't continue using M1 0W40 (unless you're operating an '07 diesel auto) since it's widely available and meets the required spec(s).
Here's the direct quote from
http://www.whnet.com/4x4/oil.html
" MB sheet 229.51 approved oils; low ash long life
Mercedes pioneered this new spec for passenger cars with diesel engines with EURO 4 or Bluetec exhaust particle filters and longer service life than the 229.31 oils. The spec was introduced in 2005. Change intervals increased to 20,000 kilometers. Based on ACEA A3 B4 and C3"
However, I believe you as the earlier quote say it works for both diesel and gasoline engine. By the way, I have the 98 E-320 and has been using Mobil1 0w40. As I said earlier, It shouldn't make that much of a difference as 0w40 is still an approved 229.5.
What's strange is that 229.5 (0w40) can go up to 30000km while 229.51 (5w40) goes to 20000km so is 229.51 (5w40) really a better oil?

Again, 229.XX is the standard for both gas and diesel autos.

Using any of the 229.xx oils in your 1998 gas car is fine and "approved". M1 0W40 certainly is a well-suited choice.
The 229.51 spec represents the latest in engine lube oil technology. Is it "better"? Dunno. The jury is still out and we'll have to wait and see what wear levels look like.

I appreciate your input.
See uberwgn's replies above, 5w-40 is an formula M type (not the same as teh 5w-40 for diesel available at stores) and is dealer only. This is not available in stores for those who want to change their own oil (unless you buy from dealer, in which case probably it is not worth changing it yourself).
I think this only leaves the 0w-40 for those who want to use Mobil 1.
