Especially with equipment that tends to get pushed hard.


I guess that all depends on one's definition of "unnecessary". I think the little bit of extra I spend on changing more frequently than recommended is money well-spent in the long run. YMMV.

FWIW: I think the 3750 oil change interval that Nissan recommends is on the conservative side and, for many drivers, could be extended to 5-6k with no problems. But, once again, that's just my opinion.
