I sure do look into my radiator,transmission and diff when i change the fluids.
If you lived in Germany you should well understand the American mentality about wanting visual proof.
Germans are much worse,we not only want visual proof but all the data that goes with it i.e. sludge reduced by 2.7 mm in the head area and 3mm in the oil pan,a sludged engine would need to be taken apart by the TUV or Dekra and documented to satisfy most Germans.This can clearly be seen with liqui Moly products.
