A person reached out to me on kijiji, and he mentioned his r-class 2009 R320 bluetec did the same consumption of oil in the past. He mentions his oil consumption started at 195000 km. He kept refilling the oil initially as the issue persisted. He was told he needs a new engine. A mechanic recommended he use thicker oil. He started using Rotella T6 15W-40 oil. He says that his oil consumption stopped. He tells me he has 395,000 km on the vehicle, which is unreal. Is this story too good to be true? Has anyone else used much thicker viscosity oil and had good results? From a mechanistic point of view, it could make sense (if oil is more viscous, less is getting past piston rings or valve stem seals).
Has anyone else run more viscous oil in their OM642 engines, and had success?
Yup using the correct oil for a diesel (15w40) can have dramatic effects on oil consumption. That 0w30 or 5w30 Mercedes is telling you to use is complete nonsense and the root of many problems on this engine.

It was so nice to drive, and loved the torque.

Mercedes does call for a 228.31 oil as acceptable for probably 90% of there truck engines. OM642 is not on the list, that being said 15W40 is both a great diesel oil for most MB and many/most other truck engines and even smaller 4 banger engines (use it in my mini excavator). The ash is <1.0 so acceptable for all current DPFs and SCRs but theres no telling whats in the additive package that MB requires for there car engines vs the truck engines.

500,000 mile sprinter. Guess what oil he's using? Spoiler alert: it's not that low ash 0w30 5w30 229.52 nonsense. https://youtu.be/eOG-Zu5TDx0When you own one of these engines you have to make a choice between your engine or your DPF. Choose wisely.

Take it for what it is, just linking the info for those that cant/wont do research to forumulate there own opinion.

Like stated above just linking information, MB was the ones that put the "spelling errors" in there certified list of lubricants. Dont use that against Americans when its the Germans that wrote it. Understand your annoyed with the above poster but please refrain from insulting your neighbors.

Are we talking about the same muppets brilliant Germans that cheated on emissions, were forced to issue the AEM recall and paid billions in penalties to the owners and governments where they were caught cheating? Remind me again anyone should still believe them?

Easy cowboy... why don't you ask your countryman here first to refrain from insulting his (and your) neighbours? And, I said ignorant Americans, not all Americans. There are plenty of vile little turds that revel in their own ignorance and choose to start hurling ad hominem attacks and insults when they can't substantiate their opinion with facts, and we have plenty of them in Canada as well (as I am actually "there" now in Sebring). I don't have any beef with you or anyone else that can have a respectful conversation and dialogue about something regardless of where they are from, but when the rabid little creatures start to bite, I bite back.
P.S. Und ja, I know it was zee Germans that wrote it, and I don't have any problem with it. Ein Schwaben Bräu bitte makes everything work out just fine.

Spilling the lies again?
MB was not proved to be cheating and there was no recall for emissions.
AEM is voluntary settlement.
Sure the Bluetec technology was disappointment when it come on the market, but MB stands up to it and did it right with AEM.
Just wanted to point out that the 5w40 mobil 1 turbo diesel truck oil is CK-4/CG-4 which is a low ash oil. Its the current certification for diesels in the US with DPFs and SCRs. Basically its not or shouldnt have any effect on a sprinter vans emissions system unless you have excessive oil burn to the point probably need a new engine anyways.

M1 TDT not a low ash oil.
ACEA E7 is full SAPS and E9 is mid SAPS. Notice the bottle has nothing to say about DPF and the only manufacturer endorsing it is Cat for their older non emissions controlled engines. If you want your engine to last 500k miles like the guy in the video, don't use low ash 229.51 or 229.52 oil. Mercedes wants you are sacrificing your engine to save the DPF.
CK-4
SAE J300 viscosity
xW-30, xW-40
D874 Mass fraction sulfated ash, %, max 1.0
D4951 Mass fraction phosphorus, %, max 0.12
D4951 Mass fraction sulfur, %, max 0.4
CK-4 (previously cj-4 I think) is the rating called for by modern cummins/ford/chevy diesels with dpf/scr. Same rating on T6 and delo400 and so on. Not sure if its not a low ash oil how it can hold those certifications. Cat also only has those two certs on the T6 and delo and similar just FYI.
How many kilometres of your w166 bluetec Diabolis?
Have you had oil consumption issues?
On the 2015 I currently have, about 80,000 kms. It doesn't use any appreciable amount of oil and I never have to top it off between oil changes, which I perform every 6,000 kms or so. It has towed a ~5000 lb trailer for about 20,000 of those 80,000 kms, and the rest of them have been as a DD in the city, albeit mostly used on longer commutes lasting over an hour each way.
The Sprinters go considerably longer as they are in constant service and we do regular UOAs on them so they get between 12,000 and 16,000 kms between changes. Even the two high-mileage mules with about 400,000 kms on them get maybe 0.75 liters of oil added after about 8,000 kms when we do a UOA, so they use about a liter and a half per 16,000 km on average. None have any emission control components disabled - in other words, they are the way they came from the factory.
All of them have always used either OEM Mercedes or Motul Specific MB 229.51 - and since it came out, MB 229.52 - oil, always in 5W-30.

API is made up of the oil manufacturers and it merely issues guidelines. If the manufacturer pays it's dues to the API it can put the API stamp on its bottle. It's as simple as that. The API isn't wagging the naughty finger at Exxon if their oil didn't follow their spec to the letter.

OK. Same can be said of alot of things. Like I said the american (ish) manufacturers use that spec as there oil requirements similar to MB requrieing 229.52 in Germany. Everyone pays the same except for some like amsoil, redline (which has great fluids),..... ect.
The 1.0 ash content is generally used fully by manufacturers but it is a limit for the spec that is adhered to. Hence why T6 is/can be used in the various US diesel trucks with the same emissions requirements as the MB or VW or BMW vehicles sold over here. Now they all have there own oil and other fluid specs that they make people pay for but that is common across the board just different specs for each. Like I said the modern cummins/Ram I6 trucks requires either the mopar spec OR CK-4 to uphold the warranty. If it was going to destroy the emissions system (DPF and SCR with DEF injection) it would not be required by the manufacturer.
Its the reason that person can run a CK-4 15w40 in there medium duty van and not clog up the emissions system. Where the issue arises is that some manufacturers may require special additives that are required for that particular engine. The 5 and 0 wieght oils are generally just for fuel mileage gains although really minimal.
Anyways a stamp on a bottle is the same as MB or API or anyone else does if you want to look at it that way.
Oil is cheap compared to these emissions systems, and the engine itself, so, I'll stick with an oil that at least meets the 229.51 spec. I used to use Rotella T6 in everything from my lawn tractor to motorcycles to my Duramax, but I won't be using it in the GLK unless they update the numbers on the bottle. It's just not worth the risk, to me. I can get Pennzoil Euro L that meets 229.51 for about the same price.
Hello. New to this forum but not new to burning oil issue on my 2009 R320 Bluetec. Does anyone know of a "fair" shop in the Toronto area that could look into this issue.
Joe, I would replace the pcv valve which is cheap and easy to DIY. If that does not fix it, sell the car because its probably your piston rings are stuck, which would need a major engine rebuild. If you want to rebuild, maybe check with EP auto in Barrie.
Well this issue never materialized until i had the field measure recall completed. I believe the PCV Valve would have been changed at the time. i have also tried 5-40 (MB 229.52) and it is only marginally better than the 5-30. dumping the car is not much of an option as it is virtually worthess with a bad engine and i can't in good conscience sell it as otherwise.
