Diesel engine oil just have more detergents right?

That is true. However, I think there are other differences. Supposedly It can help clean sludge and other crap from your engine.

put it in my 530 and seems quieter but then again against dead old synthetic conventional oil would have probably done the job. Seems good so far and picked up almost 1 MPG with it.
