I´m running 5w40 motul 8100 excess -
https://www.motul.com/br/en/products/8100-x-cess-5w40 - on my 130i since i got it, in 2017, and changed it twice a year.
Already did 6 trackdays, no issue at all, the oil temperature usually maxes at 266°F, and the highest was 275°F on a really hot day.
Is it ok?
