If you change the oil filter and use full synthetic you can go 10k. Been doing that since new with my 2017 VW Alltrack. Burns zero oil at almost 100k miles. Some people do prefer shorter intervals like 7-8k. IMHO - changing full synthetic and filter every 5k is unnecessary. Full synthetic can actually go more than 10k between changes but I don’t push it.

However, you might consider using a shorter interval like 5k for your first synthetic change. It will probably be dirty if conventional oil was used by the previous owner.

I used to go 5k between changes using conventional oil on my 95 850. Then switched to longer intervals when I started using synthetic.
