That is a possibility. We have to keep in mind, though, that today's
engines are WAY more sophisticated and capable than yesterday's. Just
think, a 3.5 liter V6 pushing out 300 HP. That was freaking un-heard of
from even a 5.0 liter V8 back in the day. Because these engines work
much harder, get hotter, are built to tighter tolerances, and a host of
other reasons, a little more oil consumption may be a small, even
miniscule trade-off for the incredible bang for the buck we're getting
with today's motor. They do all this AND get better feul economy AND
burn with cleaner emissions. Gotta luv it.
1 quart every 1000 miles? I'll live with that.
By the way, considering 1129's problem, the oil consumption may be OK
since its about 1 qt every 1000 miles. Bear in mind that synthetic tends
to burn off or leak out quicker than dyno oil, so you'd expect synthetic
oil to go down faster if your dyno oil was going down a bit already.

Think were all that oil is going... think catalytic converter?

If these newer engines are built to tighter tolerances they should use LESS
oil!!!

In general that's true, but there are tolerances in every manufacturing
operation. It doesn't take much to consume a qt every 1K miles. It
doesn't effect the life of the engine and the oil is burned in the
converter. You can complain to Nissan, but you won't get very far.

The oil will clog the converter.

Not if it's working correctly, it will be burned. We're talking about a
very small amount of oil over a long time.

What is the source of your information? Experience? literature? Not
being offensive, just curious.

If the OP hasn't discovered a solution yet, check/clean/replace the PCV valve.
