My 7.3 Powerstroke was run most of its life on dino oils and I sold it with 300,000 miles, running perfect in truck, who was hauling over 30,000 lb quite often. The fuel it burned on those 300k miles, would power my Bluetec sedan for couple millions. miles.
Still after reading about seized OM642 engines, what points to using older generation oils, I am religious about using 229.52 category only
If 229.52 is somehow a superior diesel API CK-4, why doesn't it have a CK-4 rating? It would open up the market to a lot more applications.
It already fits all applications it needs to; Mercedes.
If Mercedes didn't spec an oil that is CK-4 rated, its because they determined it doesn't need to be.
Simple as that!
Should/could it be used in non-mercedes diesels? Absolutely not unless they specifically list 229.52 oils.
I was/am very interested in oils and such - although I don't have nearly the background education that some (maybe all?) of the guys here on the forum do about oils. But I read through this thread to gain more info.
One thing I always "thought" was true about oil ratings was that the oil company had to pay to get it tested to achieve the rating? IF that's true, then maybe Mobil hasn't just paid to get the CK-4 rating?
But... back to why I quoted your post, Tjts. I read through the post you linked to and I think you have your info confused. He did NOT say he used Mercedes spec oil... he said he used "Mobil 1 0W30 or 5W30". He did NOT say he used ESP or even an MB approved oil. Later on he said (after using Seafoam... which may help) he used the "recommended Mobil 1 5W-30 ESP" and currently has (had) about 90 miles on it.
Nowhere did he say he previously used the recommended oil. And nowhere did he say he is still having issues. Maybe he did and maybe he does - but HE didn't mention that - so what you're saying about this instance is only an assumption at this point.
I'm not saying any of that to knock you - just that it's good to NOT make assumptions. More info from the OP would be needed.

This is the whole point of my post. Many people don't take the time to see there's a HUGE difference between "Mobil 1 5W30" and "Mobil 1 5W30 ESP" for a diesel engine. "Mobil 1 5W30" is not designed for a diesel engine, but a lot of people out there don't take the time to see there is a difference. Then they blame the car when they don't use the proper oil.

Logic and reason are not going to get you anywhere when talking to ****. It's not worth your time and effort to keep explaining something to someone who either actively refuses to listen to what you're saying or doesn't have the mental capacity to understand it. We've been down this road before with him.
ESP is a gasoline engine oil that MB decided was also ok to use in diesel engines because it simplifies inventory for dealer service dept and ensures that your engine will grenade before the DPF. Mission accomplished. It lacks the diesel engine oil additives that would otherwise be necessary to meet the industry standard API CK-4 for diesel engines. Mobil makes a 5w30 API CK-4 diesel oil. It is not the 229.52 ESP gasoline oil you love so much.
Only Mercedes is telling it's customers to put 229.52 ESP gasoline oil in diesel engines.

Please provide documentation to justify this statement.
(I suspect it is a Russian hoax...)
You are a fück!ng moron. You've been using pure biodiesel and you have the audacity to whine about how the engine oil is somehow responsible for your engine failures?
Have you ever heard of a property called diesel lubricity and do you know what it is? In a nutshell, it indicates how "slippery" the fuel is, and thus how much fuel slips past the piston rings and ends up in the crankcase where it dilutes and oxidizes the oil.

What a tool.
/end thread.
Your reading comprehension not your strongest quality but I find your unresolved anger issues more concerning. I feel sorry for your family and anyone that has to interact with you on a regular basis. Please get help. If not for your sake, for their sake.
I'm very glad I saw this post. I'm a new owner of a 2009 e320 bluetec and was so close to changing my oil with 229.51. Can you recommend a specific oil to me? I can't seem to find reference to API CJ-4 or CK-4 anywhere after a quick search.
Don't listen to the guy who is telling you to use the big rig truck oil in your car. Use what the owner's manual says to use.

Don't worry. This thread is full of dumb comments.
If any of this concerns you, use Chevron Delo XLE 10W-30 or Shell Rotella part 550046251 T6 Full Synthetic Multi-Vehicle 5W-30. Both meet the CK-4 spec as well as MB 228.51, which I expect is one of the specs listed for your engine.

Sure, if you enjoy catastrophic engine failure.
Newbie here so risk of being flamed by comments. I've been maintaining my cars and motorcycles for over 30 years and have never had maintenance issues until my 2014 Mercedes GL350 Bluetec OM642 which I bought new. I maintain everything by the book including the little things like brake fluid. My cars and motorcycles run forever until this Mercedes Bluetec. My timing chain stretched at 50k miles (had it replaced at 60k miles) using that Mercedes recommended 229.51 Mobil 1 ESP oil every 10k miles. (one extra change at 5k miles when the car was new) Now the car was recalled and the entire emissions system has been replaced: new DOC and DPF, new SCR & catalytic converter new NOx sensors and a 4yr 48k mile warranty on a bunch of stuff. (including turbo, timing chain and most of the top end) This is all part of the EPA settlement against Mercedes for cheating the emissions similar to VW/Audi/Porsche. The Mercedes and BMW Diesel oil is API SN so a gasoline engine oil. (without the appropriate protection for soot...etc) I started using Shell Rotella T6 at 80k miles with ACI CK-4 and ACEA E9 (also motorcycle JASO MA/MA2) and will do an oil analysis now. The car is beautiful and runs perfect again after the timing chain replacement which was done at 70k miles. Keep it or sell it? Run the Mercedes recommended 229.51/52 oil or an approved API CK4/ACEA E9 oil. I don't trust Mercedes. Worst ownership experience.
