Mobil 1 ESP Formula M 5w40 - Discontinued
 

Mobil 1 ESP Formula M 5W-40 is being replaced by Mobil 1™ ESP X1 0W-30.

5W-40 Synthetic Oil | Mobil 1™ ESP Formula M 5W-40

0W-30 Synthetic Oil | Mobil 1™ ESP X1 0W-30


For those who still want the MB 229.51 specification 5w-40 version, time to use another brand....


.

Interesting. I checked Bevo and the list both oils as approved under 229.51. But one is 0W30 and the other 5W40. So if you want or need the heavier oil, then, I guess, you would have to buy something other than Mobil 1.

My GLK250 is going in for first service in a week or so. I must ask them what oil they are using for refill.

The Mobil 1 ESP 0W30 has the 229.51 spec listed on the back along with a couple other 229.5x specs. I just completed service on an 09 Bluetec using it. I am thinking through the winter the 0W30 will be fine. Will have to look for some ESP 5W40 next spring when it returns for service.

This is what it says on the back of the ESP 0W30 bottle. I am thinking you should probably still follow proper viscosity requirements.

ugh

Well, you could always switch to Mobil 1 Turbo Diesel Truck Formula. 5W-40. I haven't checked, but I would be willing to bet it exceeds the spec.

Then you lose the emission system protection? Got to protect that expensive arse exhaust system.

Yeah the regular 5w40 TDT Mobil 1 does not have spec for the modern exhaust systems on the new vehicles.

Just oil shopped yesterday for my 09' BlueTec. Is always such a pain to find something that meets spec. Went to 4 different stores with a long list of approved oils and no joy. Found 5 qts of ESP Formula m 5W/40 but no more. Finally came home and just ordered oil online.

Went with M1 ESP X1 0W/30, my preference is 0W/40 but is isn't made in that product.

Too darn many choices and too much for a typical store to stock.

From the MB fluid sheet on Startek

Diesels older than 1997 can use 229.3 or 229.5 (or API CF-4 or CG-4) which is what M1 Turbo Diesel Truck meets.

Diesels 1998 and newer need 229.51 oil. The only Mobil product that meets that is the now discontinued M1 Formula M ESP 5W-40, or the replacement ESP X1 0W-30.

From 1998-2004 the need is due to proper operation of the FSS/FSS+.
From 2007+ the need is due to to the low SPAsh content of the oil so it doesn't kill the DPF. Doesn't hurt to have this in the 1998+, they have a catalytic converter.

According to the viscosity chart in that document, both 0W-30 and 5W-40 are approved for all temperature ranges.

Mobil 1 for 2005 e320 CDI?
 

M1 0w40 was factory fill for subject vehicle I think. Based on the service history, Mercedes dealers switched to 5w40 ESP when servicing the vehicle probably because that type could be used for newer vehicles with particulate filters.

I will probably go back to 0w40 for my next oil change.

I have been using m1 5w40 turbo truck in my 1995 e300 but it is not MB approved for the later self-monitoring technology so I am not sure it would be OK to use in the newer vehicles.

How would using TDT, for example, adversely affect the accuracy of the FSS?

FYI on both my 98 and 99, I'm being told I can go around 16k....but I doubt I'll let it go longer than 12k.

There is a dielectric sensor that measure capacitance of oil. This is apparently a proxy for oil quality. I am guessing that the earlier oils produce a higher amount of contaminants that then throw off the sensors.

FWIW the TDT 5w40 and Euro 0w40 seem to behave comparably in this respect. I think the driving patterns of my 98 and 99 are pretty similar. The 99 had 0w40 in it from PO. Both cars were on track for 16k or so.

But certainly confirms my leaning to go with somewhat shorter intervals....and especially on the chip-tuned 98, were oil changes should be somewhat more frequent anyway.

My memory says that diesel cars did not have this sensor, only gasoline motors got it. Both gas and diesel cars received the FSS system, but the inputs and algorithms were different between them.

Probably should look for it now, because in the spring there may not be any Mobil 1 ESP 5w40 left.


If you wait until spring for a 5w40, you may have to consider using these excellent oils..
Pentosin High Performance II 5w40
Castrol Edge Turbo Diesel 5w40

There have been folks using TDT in their 2005-2006 CDI with great success. It's when the model change over in 2007 to a DPF is when you can't use TDT.

I am sure you are right, at least on the W210s when FSS first appeared. Makes sense not to put the quality sensor on diesels if it wouldn't work!

I am working under the impression you got to have that ESP designation to protect the emission system. Application I am currently working with is an 09 E class Bluetec.

Yes ESP (Emission System Protection), is Mobil 1's own brand. These have special low ash formulations that are designed with lower levels of phosphorus and sulfur to protect vehicles with the diesel particulate filters. For the 09 CDI, that is very important.

Any approved MB 229.51 spec oil will meet this requirement.


.

Even if it does not have the ESP rating?

Yes. ESP is just a Mobil 1 name.

Here is a list of MB approved 229.51 spec oils.

Good information, thanks for the link:).

5w40 TDT will work well in 05 06 e320 cdi
 

Is it consensus that M1 5w40 TDT will work well in 05 06 e320 cdi which do not have the particulate filters? The oil does not have MB approval but does have a lot of other approvals.

Would M1 0w40 be a better choice since it is MB approved?

Not sure on the consensus, but M1 ESP 0w40 would work.

Your e320 CDI came with the OM648 engine. That engine can also use MB spec 229.31.

Another oil option that is readily available and meets the 229.31 spec is Shell Rotella T6 5w40 and Delo 400 LE synthetic 5w40.

Do you mean M1 0w40 (European formula)? I have not seen M1 ESP 0w40.

Though 5w40 TDT is not specifically approved by MB, it looks like it meets requirements of the Heavy Duty truck industry and therefore should be useful for the non-PDF vehicles......ie all pre-2007 MB diesels delivered to US.

That is my working assumption these days. Something that's not always brought up in these discussions: there are likely all sorts of factors that come into play affecting how different oils are spec'd. Marketing considerations and fuel economy come to mind. On the twin issues of engine reliability and longevity, I have a very difficult time believing that TDT (and some other oils, for that matter) are not perfectly fine for pre 2007 MB diesels.

I did mean ESP looking at the 229.51 spec sheet. But the 5w40 European Formula meets 229.3 and 229.5 spec, so based on the MB 223.2 sheet, it should be OK.

Agreed ..

Ash?
 

Funny I just dumped nine quarts of that into the Treg yesterday. I use it in all three cars - two diesel, one gas.

So what are you going to use? Pentosin? Fuchs? I wonder if maybe we are paying too much attention to the DPF/sulphated ash stuff and should all just use Delvac 1 or something like this dude:

Lubrication Engineers 8854 in 2011 3.0L VW Touareg | Used Oil Analysis - Diesel | Bob Is The Oil Guy

0W-30 Synthetic Oil | Mobil 1™ ESP X1 0W-30

Definitely good for an 84 grease car :)

I suspect for most here, having 5W40 discontinued is a non-event. Mobil Turbo Diesel Truck 5W40 has higher ZDDP than most and I use it my 300D. Because it is a summer car, I tend to use High Mileage 10W40 in my '72 R107. Up until now, I have used euro 0W40 in my 98 E320, but can't always get it.

BTW, saw this article about ZDDP recentlyThe Truth About Zinc & Motor Oil | Driven Racing Oil

When I now go to either one of those links, I get this site:

https://mobiloil.com/en/motor-oils/mobil-1/mobil-1-esp.

Nothing about 5W-40 being replaced.

It says that ESP 0W-30, ESP 5W-30 and ESP 5W-40 are the current ESP line of products. It also confirms the MB specs for each.

Can anyone explain this?

Interestingly, the Mobil Canada site does not include ESP 5W-40 but still has M 5W-40 and 0W-40
http://www.mobil.ca/Canada-English-LCW/carengineoils_products_mobil-1.aspx

For, say, a 98/99, how would the FSS likely be skewed using M1 TDT? I play it safe and change the oil at just over 10k mi even though FSS says I can go 15k.

According to the Mobil1 link above, there is a product selector.
https://mobiloil.com/en/product-selector

For a 1998 MB E300D,

"Based on what you've told us, your vehicle manufacturer recommends a 0W-30, 0W-40, 5W-30, 5W-40 or 5W-50 viscosity and synthetic oil that meets MB-Approval 229.3, MB-Approval 229.5 or MB-Approval 229.51. We offer these motor oils to help protect your vehicle."

The oils are: Mobil1 0W-40 European Car Formula

Mobil1 5W-50 Full Synthetic

Mobil1 5W-50 Full Synthetic
 

When did Mobil 1 come out with this MB approved grade? This might be a good alternative for summer driving on older MB diesels. Thoughts?

Who can possibly keep up with Mobil's ever-changing formulations and recommendations? It's almost comical....

They have had that for some time, but you seldom see it at retail outlets. I used to use 15W50 (still have one jug) which could be found, but on my 85 300D I now use Mobil TDT 5W40.

I also use TDT or their High Mileage grade in 72 SL (V-8 gasser). Depends on what Walmart have when I am in USA! W210 gets Euro 0W-40 or High Mileage. I guess these oils are about the same for our older cars. By the way, TDT costs C$47 (US$42) for 4.4L at Walmart Canada vs US$26.83 for 3.78L at Walmart USA.

I seem to recall Marshall (der dieseling Doktor) saying he used Delvac on his old diesels. I have never been able to figure out what is different about Delvac and other Mobil diesel oils. Because of low mileage now between changes, I am 'thinking' of going to non synthetic Delvac or Rotella for 300D.
