Well yeah, but the 1 second at startup happens a lot less than 7k rpm where the oil turns to froth because it's so thin haha. Plus the difference between 0w and 5w at startup I doubt is going to change much of anything. Both the f10 and f90s were rated for 5w40 with some other weights being acceptable per the owners manual, they changed that in 2020i want to say when they needed to meet stricter emissions standards. If you don't drive your car hard or don't track it I'm sure 0-30 is just fine, but I've seen it turn to bubbles on other people's cars.
But this is the great oil debate and there is no right or wrong answer and honestly it's just subjective and whatever people want to do, at the end of the day oil is oil and as long as you're not doing something ridiculous like 20-60 or 0-16 I'd say you're gonna be fine 🤣🤣🤣
