- Update
So, I bought the car, and with a turbo failure and engine rebuild later. My car is running fine, and I know this sounds silly, but with it being under warranty (Engine AND turbo), I'm going to stick with going to the dealership for the oil changes until the warranty runs out. This way, if there is another turbo failure (or worse), they'll honor their warranty. I'll pay a little bit more, but if the car runs great and still does outside the warranty, then I'll go ahead and change the oil myself.
