If you value your turbo you will switch. My personl experience with turbo's and dino oil taught me that. My first turbo was a Saab turbo. It only ran for 40K miles before the "coking" of the oil on the hot bearings ground them up. The warranty covered a new turbo and a friend recommended synth oil. I ran that turbo to 150K and sold it still in good shape. My next turbo was a Volvo turbo. I got over 220K miles on the turbo with synth oil before I sold it still running great.
I worked in oil refineries summers during college and remember the "coking units" that were like huge ovens that baked what I guess were leftovers from refining and formed a coal-like material, but in huge chuncks. This is basically what is happening on a small scale on the super hot turbo bearings. Even if you let it run for a couple minutes when you park it still happens. Synth does not do this. It is REALLY cheap insurance.
