Many folks have different opinions about oil, seems most fair to the the car manual, especially since any warranty claim will likely depend on following their schedule.

The toyota maintenance schedule for the Camry specifies every 10,000 miles (16000km). Unless you: are towing, have a car-top carrier, carry heavy loads, drive less then 5 miles when cold, drive on dirt/dusty/muddy roads, drive on melted snow, have excessing idling/low speed drive, etc.

Also the Camry uses a somewhat unusual oil 0w-16, there is a more commonly available variety... but they recommend a full flush, replace the filter, etc when every you switch back to 0w-16.
