Switched my Bimmer from GC to M1 high mileage

[Audi Junkie]

In Texas, I'd run 15w-40 HD and be done with it.

Why not give a BMW the good stuff?

Redline

GC

M1

Delvac 1

I like GC 0w-30 but there's nothing wrong with a 0W-40 , 5W-40 or 10W-40 in a high quality synthetic from Redline, Mobil even Shell Rotella 5W-40 15W-40 HDEO seems like its ofr a beater BMW in hot weather, or for cleaning, or high oil consumption.
