Has the level in the Engine Oil Changed?

If AT, check it also.  Drive for about 10 mile's or so at moderate speed, Stop, leave engine running, move shift through all the gears, put in Park, leave engine running and check the dipstick;

Is the level correct for Hot Range, what does the Fluid look like?

Might want to try a different company for analysis.

You could take it to Nissan and have them do a pressure test on the Coolant System. 

If it were me,, I might just keep a close watch on the Oil & Level,, as well at the Coolant and AT Fluid.

I've never done an Oil Analysis,, but I kept my '93 KC AT 2wd for 20 year's, and it was running good after I bought a '13 KC AT 2wd and sold it.

Good Luck

Dawg,

Just a suggestion;  I've alway's been told to use a Nissan Oil Filter, and that's what I've alway's done.  Be wary of Fram.

Sounds like you have a good plan.
