I think that the rule of thumb is to change the oil in a car every 3,000 miles or every three months, whichever comes first. Until recently I had always driven more than 3,000 miles per three months, so I changed the oil every 3,000 miles. I'm now only driving about 2,000 miles in three months, so I'm wondering whether it's any better for the car to change the oil after three months than, say, every four months, without driving 3,000 miles.
