"quick" oil changes

Two cars using the same oil and change interval could have completely different results based on driving habits and weather.
The sludge has nothing to do with using "quick" oil change chains. The sludge forms over time, so if you change conventional oil more often, you are giving it less time to go bad.
Using synthetic oil may make a difference, but nobody knows exactly why the deposits are forming in the engine, or if they do they are not telling. Some combined effect of crank case ventilation/emissions control, plus driving in cold weather (like northern European countries) plus short trips that do not allow the engine to warm up completely before you turn it off.
Saab is not the only car make from this period that has the problem, so it is not the same kind of issue like the loose head bolts, or failing DI's.
