No expert. Been using synthetic for countless years. A lot of cars come with it from the factory. Turbo's should definitely use it because of the heat. Supposed to give you a couple miles per gallon because it allows engine parts to run easier. It isn't subject to extreme heat or cold weather...and finally, you can go a lot further between oil changes, although most of us that use it still change the oil & filter at 3-4,000 anyway.
