Eoin, If you do any kind of stop and go driving or do short runs of a few miles that prevents the car from warming up completely, then you are in severe service. If you make any trips into a city you qualify. As for the 10,000 miles intervals, I believe after years of denial, Saab as been talking synthetic oil in the crankcase, so that may account for the the change in the late 900 and current 9-3 models. I would still rather do a shorter interval 3500 to 5000 miles. Ken Washington 87 9000S 87 900S 83 900T
