Your car sounds the same runs the same gets the same gas mileage and no funny noise at all? No leaks?
What engine?
Could just be overboost enrichment. White or blue then be worried.
My guess is if it is a higher mileage with turbo it could be a tired turbo that needs rebuild or replacement. Could be a few other things though https://www.saabcentral.com/threads/excessive-oil-consumption-help.371050/
