229.52 or 229.51???




Great oil for older diesels, but I think it can be bad for newer DPF..
If you really want to be Guinea Pig, there is Valvoline oil with great reviews on Fords.

another option is Pento II High Performance 5W-40. beside, if you compare both spec sheets (229.51 and 229.52) you will find few same oils on both, which to me means that they just override each other and is another MB twist in the specs to make some extra cash selling MB oil until more oils are approved and added. or this German synthetic oil (at least is full synthetic) Ravenol RUP 5W-40, just my two cents, vs oils made in USA.
if you go to Walmart and pick Castrol 0W-40 5 quart jug (made in Belgium) and 1 quart bottle and check the label you will see that the quart jug is labeled "Not for sale outside USA" while the 5 quart jug does not carry it.

Why the costly part wears so fast? I had MAF and Ox sensor failures, but after replacing them I had the car smog and it come with 3% of allowable in NV emissions, what shows good working engine, beside that even with clog DPF I am getting better mpg than average.
Coming to labeling in USA - most of us are familiar with Smirnoff vodka? It is manufactured on the recepie of Smirnoff brothers, who used to live in city of Lwow. That city has quite "ownership" records and the bottles sold in USA 20 years ago would say
"Smirnoff brothers, Lwow, Poland" later labels would say
"Smirnoff brothers, Lwow Russia" did not buy the vodka in last years, but I guess not it says
"Smirnoff brothers, Lwow Ukraine"
Strange how big politics affect small things in our life - can't even have shoot of vodka without entering global politics.

Mechanics and shops are the worst source of lube info. Separate subject, but yeah.

[Edit] Never mind, I followed the link and found that they don't list MB228.51. Poked around and found that MB228.51 is now called DTRF 15C110 and isn't considered "Passenger car" oil any longer. C'est la Vie

They don't really directly compare HD to PC oils, but once you know how recent the spec is, or it's origin, you can infer how good a spec it is.
Mostly we look at C3 oils for light duty diesels / DPF. VW 504 (507) is the top spec in the industry, it surpasses MB 229.51/2, both are C3 rated too. This graph is more VW-oriented, but yeah.

The red cells are worst for a given spec; green is best. Not all properties are included in both specs, hence the "-" in some cells.
I assumed that an oil meeting both CK-4 and 228.51 would score as high as the higher of the two and those numbers are shown in the right most column. LSPI Protection is not relevant for Diesel engines. In the end, the only property where the 229.5x oils may score higher than the CK-4/228.51 oils is Sludge. We don't know for sure as the truck oils are not rated for Sludge.
Based on this information, I'm thinking that the CK-4/228.51 combo oils are the best choice. I run 5,000 mile OCI, so I'm not too concerned about sludge.
TMSAISTI! YMMV, Batteries not included.
Question: is "Soot" in the auto specs the same as "Soot Thickening" in the truck specs?
Here is the graph for the truck oils:
