What are the optimal oil change intervals for the BMW Z4?

I recently bought a BMW Z4 and I'm wondering how often I should change the oil to keep the engine running smoothly. I drive about 10,000 miles a year, mostly in city traffic. Do I need to change the oil more often than the recommended intervals?

As an experienced BMW owner, I can tell you that the recommended oil change interval for the Z4 is every 10,000 miles or once a year, whichever comes first. However, city driving can be more taxing on the engine compared to highway driving, so it's always a good idea to check your oil level and condition more frequently.
