New M340i oil changes

Hi everyone. I just bought a new 2021 M340i. I see mixed opinions on here about oil change intervals. Some say to do what BMW says and change every 10k miles (or whenever the sensor says to do it) and other say to do every 5k.

The new car maintenance coverage comes with 3 years/36k free oil changes, which is basically three of them.

My plan is to do them myself at 5k and then go get the free one at the dealer at 10k, and repeat the process.

Do you guys think this is reasonable?

Also I am concerned about how the oil sensor lets me know that it's time to go to the dealer for an oil change.

For example, right now it says "next service in 9800 miles". If I change the oil at 5k, is it going to extend the service notice or is that pre-programmed?

Also, will the dealer know that I changed it at 5k based on the oil sensor. I'm sure the oil will be black in color.
