Z Broke Down :(

Exactly.....As I said in yet another thread on this, Very few manufacturers will give you the time of day if you're not burning more than a quart/1000 miles. Chevy (for the Corvette) even has a published bulletin that says 1 qt per 500 miles is acceptable if used in an aggressive manner (aggressive being defined as operation above 3000RPM's...LOL). A quart between changes, or even 2 in a 3700 mile change interval would not be considered excessive enough to warrant correction with most all companies...
When you get into the serious usage area (exceeding a Qt/thousand) they will do a monitored test by documenting miles and sealing your oil fill to determine true usage.

Very few cars on this forum are even fully broken in yet, so this discussion is all a bit of an overreaction..

Maybe Lou could let us in on Nissan's guidelines on oil usage if they have any..
