5w30 and 0w30 have been discussed many times.
Mainly looking at this picture, the content displayed by my bmw app when making an appointment for maintenance and oil change is a bit interesting:

Initial installation of vehicles produced before October 2021 5w
Initial installation of vehicles produced after October 2021 0w

Fuck, do your app also have this kind of reminder for maintenance appointments? Is that a reliable statement?
