"DrBoost", a former Saab engine designer/engineer wrote some time ago that he considered the Castrol Edge 0W-40 oil to probably be the best oil for the B2x4 engines. But any good quality 0W-40 would most likely be just fine, as long as you don't go too far between changes (~10,000 kms).
Personally I wouldn't use a 5W-40, as most of the wear occurs during cold starts and a good 0W-40 will stay in grade for at least 10,000 kms. Also, it's not an advantage to have too thick an oil at working temp (and yes, the 100 Celcius viscosity of a 5W-40 oil will typically be higher than a 0W-40) since oil flow is just as important as - if not more than - the oil pressure.
