A: no one can give a good answer, so I change mine every 5k miles. Why 5k you might ask? well its super easy to remember to change at 5, 10, 15, 20, 25 etc. no computer or sticker needed. just look at your odometer and know exactly where you are at. 5k is conservative but that's okay by me.

A lot of variables involved The only accurate way to tell is with UOA. Your 5K intervals are fine for most DDs. I'm sticking to Nissan's 3750, at least until the warranty runs out.

For most DDs, any high-quality oil will do the job.

I don't know of an engine that doesn't burn some oil. Every car I've owned burned at least a little. I don't get too worried as long as it's less than about a half-quart between oil changes.
I don't put a whole lot of miles on my Z (~7K/year) and don't have to fillup very often so I check my oil every week or two. While I'm under the hood, I check other fluid levels, belts, &c and then check tire condition/pressures.

Amen. I hate to see any equipment abused but the Z was made to be driven. If you feel like you need to baby it, maybe it's not the car for you.
I like my 370Z. A lot. The best all-around car I've owned - plenty of power, great handling, nice interior, and a sexy exterior. But it's just a car.
