Wich oil to use
 
Im going crazy
Manual says 642 engines that means ml (164) bluetec 350 4matic
Should use 229.51 oil but says restriction: use only 0w40 or 5w40 when at mercedes they give u 5w30 for 229.51 specs
What the hell should i use

The updated oil. 229.52.

Confused yet?

Riki986 03-14-2019 08:43 AM

There have been many many revisions for oil for diesel models.

Are you in the USA?

Any 229.52 or 229.51 oil will be fine. It's about the spec, not the weight.

Going into summer you would the 5w40 or 5w30.

The reason mb has 5w30 for 229.52 is because diesel gets into the crankcase oil and affects the lubriciity properties of the oil, essentially cutting it. With the old 0w40 oil any diesel in the oil made it essentially useless as oil under the xntended oil intervals. The switch to thicker 5w30 oil was meant to fix that.

I live in warm area 40įC here in summer is 5w30 good by ur opinion ?

P.s. I see from your posts youre having issues with you heating element.

If you are in the US these are the least of your issues.

I highly recommend a tune to tune out the diesel emissions to keep your vehicle reliable.

Also a full engine flush and ceratec coating to get rid of any crud, dropping your belly pans and 5k mi oil changes to get rid of any sludge that might have accumulated.

If you're serious about oil getting hhe upgraded aftermaket spin on oil filter adaptor will help against some of the problems too.

Dealer near me has only 229.51 5w30
I read in internet for bluetec it would be better to use 229.52 do u think its okay to stick with 229.51

I live in eu now and imported my car from us
I heard in eu there are no strong regulations about bluetec and there are some workshops that can turn it of at all do you think that would be a wise thing to do ?

Yes! Immediately!

You're going to be in a lot of trouble if you don't. Usa diesel cars are hampered by stringent emissions requirements that ruined the engines that eu diesels didn't have. Us mb diesels got sludge, extreme heat soak melting mounts seals and everything that could go wrong that euro mb diesels didn't.

I hear good things from green diesel engineering or something like that.

If you want mb oil 229.51 it will be fine, just do 10k km oil changes since you have a us diesel.

I like Liqui molly. Might be easier to find for you two in eu. https://www.fcpeuro.com/products/5w3...ui-moly-lm2011

For a gasoline car you would want something else. But because the diesel has issues with hhe fuel washing into the oil, diluting it and making the oil thinner you want 5w30 to stop it.

Ow40 with diesel in it turn into a 0w50/60

5w30 should be OK if you also Do 10k km oil changes for 5k mi

These are all the 229.52 oils approved by mb

As you can see everything is 5w30 except for shell which also has 0w30. And the 1 manufacturer who has 0w40 is mobil 1. Stay away from it!

Eu 642 diesels didn't have those issues. In the family we've had 5-6 of the eu 642 without major issues really. The US ones are riddled with probl ms.


No I haven't

Riki986 03-14-2019 10:45 AM

I have an w203 c220 cdi 2005 300000km on it and jts a fkin tank lol but this bluetec is driving me nuts
I read there is a bypass module and some guys can turn it of by programing but this programing thing doesnt sound very legit lol

Riki986 03-14-2019 11:52 AM

Do u have any information about EGR/DPF/SCR/ADBLUE Delete

Plenty of places if you search for bluetec tune or dpf delete or bluetec emulator

Riki986 03-14-2019 12:41 PM

U think it can pass emission regulations here in eu if egr dpf delete
Spoke with a guy he said i wont remove the exhaust ill only drill some holes in it so it wont get blocked
I hope it wont produce to much black smoke lol like a tractor if i delete egr and dpf

Ooof. I don't know about that. I would ask the owners in the diesel forum who've had the tune done.

Riki986 03-14-2019 01:51 PM

In my state the limit is 3.00m i dont know what the hell is that lol mg of co or what
But the car in the last test did 0.78 so it passed
The test it says
Smoke 0.78m passes
Limit 3.00 m

Specification 229.51 is essentially obsolete and is replaced by 229.52.

This is a fuel economy measure, as by definition .52 is 30W.

If you want to read about it, find API FA-4 here

Riki986 03-14-2019 07:19 PM

if you had yourMercedes dealer change your oil,thatís what they would use because thatís all they have. Mercedessays itís ok.

and, of course, outside temp makes no difference because your engine temperature is regulated by thermostat and there is plenty cooling capacity to keep it under control
