Just FYI:
The majority of the people I know that own turbos, regardless of make or model, switch to synthetic oil as soon as they get home from the dealers (if the car was not factory filled with a synthetic oil, like Mobil 1). This is to prevent possible coking in the turbo bearings and seals from regular dino oil, not to mention your rings too. IMHO, to say you need to "break-in" an engine with dino oil before switching doesn't make sense, if cars are coming from the factory filled with a synthetic oil. Would one dump the synthetic oil and put regular oil in it for break-in purposes? The brand of oil you use is up to you. Regular oil and filter changes should follow the manufactorers recommendations to keep your warranty intact. If you want to do an oil analysis and just change filters to stretch your synthetic oil investment, you may find it may be cheaper just to change the oil and filter (Amsoil charges $25). Some dislike the hydrocracked group III oils and prefer only PAO based (group IV) oils like Mobil 1 or the more expensive Amsoil (their higher end products). The latest preference, even at bobtheoilguy site, is ester based synthetic oils like Motul 8100 Ester E-Tech 0W-40 or the available only outside of the states Mobil 1 0w-40, etc. Any of the "Synthetic" oils do have a superior additive package which will help keep your engine clean. I have used/switched immediately to synthetic oils in all my cars since the 80's and have not experienced any problems and the inside of the engine still looks like new with no/minimal deposits and runs great.

It's nice to be important, but it's more important to be nice.
