How offten should you change the oil in your Volvo S60?

it depends on the car and driver. i drive my Volvo hard, and its turbo charged so i replace the oil every 3000 miles with full synthetic, if its a turbo i would replace it with only full synthetic and at most every 5000 miles.

if it is a regular one, any kind of oil will do and change it between 5000 miles and 7500 miles only if you drive very lightly on the car.
