3 of our 4 cars are turbocharged, and they have all received Ye Olde Mobil 1 and a good filter - often - from Day One.
No offense but mobil 1 is way too expensive for an oil that is primarily group III base. When they used to use PAO as the main stock it was a bargain but now........not so much. Delvac 1 and rotella t synthetic are a much better bargain from the same oil stock as mobil 1, but without the extra cat saving and energy saving (mpg) junk. Besides that when your driving a car with 12+ quarts of oil between changes, i would try and get the most out of it i can.
