I do about 4,000 mile change in summer towing my camper with whatever filter and 5-7,000 miles in winter with a Fram Ulta for two changes. Seems to work out fine but the small filter on Nissan's 4.0 V6 makes me nervous!
It is the V6. I had to double check the maintenance schedule to make sure I wasn't remembering wrong. Strange thing is, there is no severe-service oil change interval (if I'm reading that correctly). The only severe service fluid changes are at 20,000 miles for ATF, diffs, and t-case. I'm figuring on splitting the difference with those and do them around 30,000.

By the way if you tow anything run a solid 10w30 or better in that V6 and change it early the VQ40DE timing chains can shear oil like a bad thing at high RPM
My Frontier manual also has 7.5K service intervals for oil, which is what I've run for the 191,000 miles I've had it. Interesting you mention the shear - I've not seen any issues. But I've only done 3-4 UOA's.
