David, If you're asking about not changing the oil AND filter at the same time, then yes you may be able to get away with longer service intervals. If you are asking about changing the oil but not the filter then I would say that that is a misrepresentation of the advice provided here. On the other hand, changing the filter but not the oil might be an acceptable strategy if you knowingly have a poor quality filter but exceptional oil. In some circumstances there are oil filter d/p gages and changing the filter conservatively based on d/p would be appropriate.
