the trend from many manufactures is to spec out lower viscosity oils in the interest of better fuel economy - but on a turbo or a gdi engine I think that may not be the best.
I think on my 1986 9000T I would run 20w-50 in the summer months. That engine was like new when the car was totaled with 230k miles - it used hardly any oil and compression was high and even in all cylinders. Not so with the 2004 9-5 as it will burn a quart or so between changes.
