If it is the synthetic blend, you should change the oil every 3,000 miles. If it is a full synthetic, you should change the oil every 5,000 miles.
Change it every 5,000 miles if you use conventional oil or every 7,500 if you use synthetic oil. Also change the filter at every oil change.
If you drive normally change the oil/filter every 8,000 miles.
Every 5k with conventional oil. Every 10k with synthetic oil.

Synthetic. Turbos should always be synthetic.
This depends on the oil that goes into the car. If it is synthetic you need to change it every 10,000 miles if it is regular than it needs to be every 3000-3500 miles.
5k with Mineral or 7.5k with synthetic.
Neither. I would recommend you change it every 8,000 miles.
