MB originally required oils meeting MB approved 229.51 of which Mobil 1 5w40 ESP Formula M was one and that is what the MB dealers used. Mobil 1 stopped producing Mobil 1 5W40. MB changed their Spec. to MB approved 229.52 which is supposed to be better for the turbo. The dealers now use Mobil 1 0W30 ESP X1 which has MB approved spec 229.52. There are a multitude of oils with that approved spec. that can be used.

I personally like the Mobil 1 products so that is what I use.
The link is to a table of approved MB oils.

I should cry "uncle" but I won't. You left out salient information in your statement. The current oil change interval for MBS engines we are discussing here, is15k (up from 10k). Non-synthetics will not stand up to the increased heat, and recommended duty cycle from the mfg. for that mileage. I'll tell you this, if you decide to run non synthetic, that doesn't meet the 229.52 spec, you will not prevail in any oil related engine failure under the stated warranty periods covered. Oh, and one more thing on that, in addition the 229.52 spec, also incorporates a "low ash" formulation, which is also necessary to limiting potential problems with the DPF, and thus, getting the recommended life cycle from that expensive exhaust system component.

Many of the oils listed are not synthetic, yet they are approved and meet the specifications. I've moved to the approved Amsoil European oil, which is a true full synthetic - in part because I prefer Amsoil and also because I did not know the factory fill was a synthetic.

So it's interesting that MB requires synthetic and installed it at the factory. What is your source for this information?
This came from pg 323 of the 2015 Sprinter Owners Manual:

Miscibility of engine oils!

Mixing oils reduces the benefits of using high grade engine oils. We recommend that you only add engine oil of the same quality grade and SAE class as used when the engine oil was last changed. If, in exceptional cases, oil of the type in the engine is not available, top up using another approved mineral or synthetic engine oil.


Mineral oil?

Any time I talk to a service person and I ask them about Synthetic oils they say don't waste your money. Just keep fresh oil in the engine by doing the changes on a regular basis. When the rig sits over the winter months make sure there is fresh oil in the engine , same applies to my motor cycle.
In the end I think its a matter of personal choice but clean air filters and regular changes are the way to go. More dusty environment, more heavy duty usage of the engine, more changes. The biggest enemy of any engine or transmission is dirt and heat..

I agree with that since most "synthetic" oils are really a blend of petroleum and synthetic oil. Some of the Mobil 1 products are true synthetics. I'm sure there are other brands that are true synthetics, but they are the exceptions. If only for MB warranty purposes, best to stay with their oil specifications. Very expensive engine to replace, especially if you are paying for it.

By "mineral oil", one can assume they are referring to non-synthetic oil (what many of us call dinosaur oil). I don't believe they actually mean mineral oil - which we run in air-cooled piston airplane engines during the first 50 hours or so for rapid wear/seating of the rings and cylinder walls.

I still haven't seen a reference to the requirement to run synthetic, nor that MB used it for the factory fill.

I certainly won't argue with anyone that synthetics are a better all around choice regardless of turbocharged or normally aspirated. I run synthetic oil in all of my internal combustion engines and everywhere else lubricants are required.

I'm currently driving a Super-C Class diesel puller (2015 Dynamax DX3-37RB). It has a Cummins, 9 liter, 350 HP diesel engine. Cummins Service Centers do NOT use synthetic oil in these turbo diesel engines. When I asked about it, I was told that if I wanted synthetic AND brought it in, they would install it BUT, Cummins specs were for traditional petroleum based oil. 2016 is Cummins 101st year in business. I'm sure they know what they're talking about after 100+ years building diesel engines.

You would sure hope so. But then again; "Augsburg, Germany on August 10, 1893, Rudolf Diesel's prime model, a single 10-foot iron cylinder with a flywheel at its base, ran on its own power for the first time. That same year he published a paper describing the internal combustion engine to the world. In 1894, he filed for a patent for his new invention, dubbed the diesel engine." BTW, they, Cummins began putting diesels in cars in the early 1930's. Not there not one of the better diesels now, just that Europe has about 50% of their cars on the road, powered by diesels. So, it would be a safe assuption that more expierence in that theater, transfers to the US market with more technical knowledge. Just an observation.

Cummins makes very good diesels and they have germany to thank for their inovation.

Although it is interesting to know what other manufacturers spec for their diesel engines, this is a Mercedes Benz dedicated sub forum. The number one priority for the Sprinter is to follow MB specs, especially regarding engine oil. I am certain that the oil that is in the new vehicle is synthetic, as the log service intervals they recommend, 10000 to 20000 miles depending on model year, cannot be achieved without synthetic oils. Knowing what Ford, Chevy, or Cummins do is not relevant, and could confuse folks that are new to the MBS chassis. Using out of spec oil will lead to a warranty issue if there is an engine failure. The type of oil in the engine will be the first thing they check.
