So if your Z used "some" oil (or no oil at all), consider yourself lucky.

That's the general rule of thumb for most manufacturers. My 2010 roadster started out consuming oil (got it with 2.4K on its ticker, probably with factory fill still and it was > 1qt low when I first checked it). Based on my driving conditions, I run 6m OCIs and by 20K consumption had fallen to 1 qt between changes of about 5K miles.

I have run up to 7500 mi on a OC (always using 5/30 Pennzoil Ultra to date). 38K now, added .5 qt after about 4K miles

This is completely normal for any car IMHO.
