If your Saab has a turbo, use synthetic. I've owned second-hand classic 900s and the first thing I did with them was a good engine flush and oil change, using Castrol GTX Magnatex 10W40. I've used this oil on two turbos and an injection. On older cars where the oil used by previous owners is not known, there is a risk that synthetic oil will clean away mineral deposits and slight leaks may occur, but I've been lucky. I use Magnatex because I belive the advertising hype that there are magnetic compounds in the oil that cling to the engine protecting it from cold start fire-ups :) I usually change the oil around 3000-5000 miles depending on how hard the cars have been driven and what the oil looks like from my weekly checks. I think for a 2000 model 9-5, a synthetic oil would make good sense. Paul 1985 900i 16V 1989 900 Turbo S http://pjgh.go.dyndns.org/saab/index.html
