Change it according to what VW recommends as listed in your owners manual.
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.
It depends on the year.
If you drive normally change the oil/filter every 8,000 miles.

How do I replace a turbo in 2003 vw passat
OFTEN!!! never go over 3000 miles and only use full synthetic 5w40. I personally change my oil every 1500 with synthetic, some say that's crazy but I have close to 100k and have never seen the oil light come on. I have known many who have used regular oil or not changed it enough and the engine and turbo failed at 40000, costing $9000
never
Every 5,000 miles with conventional oil, and every 8,000 with synthetic.
I dodged the bullet on that one by not using synthetic oil in my car. If I did, I would be sure to change it at least as often as my owner's manual stipulates so I don't void my warranty.
Every 5,000 miles with conventional oil and every 8,000 miles with synthetic.
If you use conventional oil then I recommend you change the oil/filter every 5,000 miles. If you use synthetic then change it every 8,000 miles.
If you drive normally and use conventional oil change the oil/filter every 5,000 miles. If you use synthetic change it every 7,500 miles.
