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.

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.
