As for the engine breaking-in period, I followed what the manual said, and tried not to rev about 4k rpm for the first 1200 miles. In fact, I set the rev limiter light at 4k rpm. Occasionally, it would jump to 5k rpm just because it's impossible to keep it under 4k ALL the time. I did that probably a handful. When I drove on the highways, I downshifted a lot, to pass, etc... so I let SRM do its magic. So the revs were varied throughout. Could I have done this MORE? yes... probably.... but I think for the most part, it was sufficient.

I also downshift when coming to a stop light/sign, so again, SRM does its magic. So I would *think* that my rings are seated pretty well, but since I only have 1800 miles, I'm sure there's still some "seating" going on in there. So I will continue to vary accel and decel / engine load as much as I can, and avoid using cruise control.

Any other suggestions?
Sounds like you did it right.

FWIW, the GM tech that took my car onto the rollers at Bowling Green got it up to 4400rpm, and he wasn't a weenie about getting it there, either. Got it up to 83mph, too, from what I recall (in my manual, some BS about 55mph=max for break-in).

You did all you can do to "do it right" it sounds like.

Don't forget though, perhaps even more than the engine, you are breaking in the axles, wheel-bearings, clutch surfaces, brake surfaces, rotor surfaces, flywheel surface, transmission internals, etc. This is all important, too. Whatever you do, do NOT "shock" the drive-line until it is worn in. My Z06's manual says "No HPDE's until 1500+ miles".

Good advice imo.

If you determine that you are using too much oil for your taste, by all means, begin the process with Nissan.
