How often do you change your oil?

[Dime]

How often do you need to change your oil? I assume that a large majority of us change our oil every 3,000 miles, sticking to a "better safe than sorry approach" as far as mileage, even though the manual (as I recall, I don't have my manual sitting in front of me currently) and oil providers suggest larger intervals.

But what I always wondered was time. Some say every 3,000 miles or three months, which ever comes first. Others say every six months. Others every year. And, the manufacturer of the car and the manufacturers of the oil never mention a time you need to stick to as far as oil changes.

With the little amount of driving that I do in my car personally, and the fact that I allow the engine, oil, and everything to get up to temp, changing my oil every three months sounds to me like big time overkill.

So, what is the general consensus of the ZR-1 gods? That is with normal spirited driving conditions. Ever three months, every six months, every year?
