I've had this sound for a week. didn't exist before that. The sound comes when the engine is warm. It disappears after 2 rpm. My friend said it was an lifter tick and had the same issue on his 328, put mobil1 10w40 oil and the sound was gone. 2,000 km to oil change. what do you think i should do? Is there any harm in using the car like this?

sound like in this video

Not a loose plug noise.
It's Lifter tick.

Three possible solutions:
A different brand of oil often solves (different additive package) the issue.

Liqui Moly Hydraulic lifter additive.

Replace the lifters.

Can this one b shorter than the last...

Which oil should I use? What should the thickness be?

Please do not start a 100 post oil thread.
If it works for your friend, you have proof right in front of you!

I apologize.
However if you use the search function at the top, there are 24+ pages of this very same question.
Try an oil change of brand. Take the car out for a spirited drive and see if that solves your issue.
