A question for the car geeks

[giza]

When I worked in the suburbs, I would put around 2,500 miles on my car every 3 months, so I would get an oil change every 3 months.

Now that I work in Center City, I'm lucky if I drive my car once a WEEK, so that means I'm going to be getting far less than 2,500 miles per 3 months. In fact, I suspect I'll be seeing less than 1,000 miles per 3 months.

So, my question for the car geeks out there is: do I still need to go in for an oil change every 3 months? Or can I stretch that out for a long period of time? Keep in mind that I'm not much of a car geek, so I don't do any maintenance on the car myself.

Comments appreciated.
