This is commonly asked by many motorists. Globe and Mail Automotive Columnist Rob MacGregor fielded this question from a curious driver.

Hi Rob, I have a 1999 Saab 9.5 station wagon. It only 4000 km on it when I purchased it in 2000. It is a 4 cylinder turbo and has always used regular engine oil, changed every 5000 km or so. I have been advised that I should switch to synthetic oil because of the high heat generated by the turbo. My car has 142,000 km on it and has generally been a good car. Do you think I should use synthetic oil from now on or stay with regular oil? Most of the time I use the car for around town trips.
