There are 3 types of dust issue. Most dust is removed by having sensor clean operate each time the camera is switched on. "Sticky dust" (usually pollen grains) and dust with high static charge may need a special clean - and neither dust type is likely to come from camera internal parts.

There are 2 types of oil issue. The first is sensor cleaning swab contact touching an oiled part close to the sensor. The second is oil spatter from a moving part close to the sensor such as the mirror lift mechanism or sub mirror, and perhaps the more distant aperture stop down mechanism.

I have had swab contamination when first cleaning my D3. Many quickly learn not to repeat this mistake as further cleans are needed to get a good finish.

Perhaps a reason oil/dust is perceived as a D600 issue is many are trading up from 12 MP. Then the extra 100% magnification shows up any sensor marks more easily.

Another possible cause is trading up from DX to FX. The larger FX mirror disturbs more air - and any dust on the rear lens element.

Many problems turn out to be a lack of intimate knowledge of complex modern camera equipment.
