Makes no difference
It does not matter.
If you follow MB's recommendations on weight of oil (which you are) the brand makes no difference. None. Don't let the "oil Nazis" or clever marketing/branding fool you. Oil is oil. If you change it hot and change it often it does not matter what brand you use. FYI - I use Rotella as well. It is cheap and readily available at WalMart. I pick up two gallon jugs there every couple months.

Brands mean nothing...........but advertising.
The only thing you need to look for is an oil with diesel rating: CH-4, CI, etc....
(I believe I have read that turbos should use at least CH-4.) I have read that the diesel rating shows that there is an additive for soot suspension. So yes, the Rotella is fine, as are many, many other brands. Many of which, probably come off the same factory bottling lines.

I don't agree that there is no difference, but any oil of the correct weight with a diesel rating will meet the minimum requirements. Rotella 15W40 is fine.

X2. Some of the API diesel oils have much higher NOACK values compared to a 229.5 oil. They're not all the same.

As long as the oil has a Diesel Engine API rating it should be fine (ie.CI-4, CH-4, CG-4, CF & CF-4. The 15W40 weight oil was developed for diesels....I don't think there is a single brand out there in this weight that does not meet the API Diesel Service Requirement which is backed up by all the diesel truck,tractor, marine engine and diesel auto makers.
Rotella is a brand thats readily available in the US and Canada and its reasonably priced. For winter I like blending Rotella 15W40 with their 5W40 synthetic which is also Diesel Rated. Having some 5w-40 synthetic in there helps with cold starts in winter conditions.....just a little better cold flow characteristics. Cheers,

What about the True synthetic vs part synthetic blends?
Rotella synthetic is really a blend right? Mobil 1 5W40 and 15w50 are true full synthetic oils right? this makes them better at handling shear loads and soot control...
as long as the oil meets the requirements of the motor, and is changed frequently enough, with filter changes, the MB will outlast you. John

Saying oil is oil is giving sloppy advice. Oils are rated differently, have different soot protection levels, different lubricity levels, different additive packages and TBNs, different shear numbers, etc. This data adds up to tell you whether the oil is going to go the distance for you or not. They're not all the same. I use the best I can get so I can extend the drain intervals a little bit while providing my car with the most advanced protection possible as I look toward taking the car to 500k and hopefully beyond. I care about my car. I drive the crap out of it but I maintain it very well and good oil is one of the things it always gets without question. If you are religious about the 3k interval, any CH-4 rated oil of your choice will provide at least the minimum amount of protection however.

My data is from mid 80's, Agricultural Engineering. Most of the major engine Mfg. attended the annual convention and all said that the then 'modern' oils where far better than the past oils except paraffin-based oils. Granted this includes gasoline burners. But the point that struck me is that all oils where only 1/3rd oil & the rest was additives! So the synthetic vs. regular oil question is a bit gray or blurry.
If you talk to Cat, Cummings, Mack, ... they all say use rated oil suited to the climate, check level often and FILTER, FILTER, FILTER. I like Mobile 1 in pricey car engines and manual trany, but for my WVO MB Volks-Panzer, Rotilla. Diesel oil needs a more aggressive cleaning action than gasser oil.
