On my '95 850 it is every 10,000 miles.
On my '01 XC70 it is every 7,500 miles.
On turbos it is more often.
There are 2 different lights:
Service light indicates routine service. It is triggered by the
odometer. It is predictable and can be anticipated.
Check Engine light indicates the computer has detected an abnormality.
It usually has a sense of urgency connected with it.
