Which 0W-40 are you planning to use? Why 0W-40 and not 0W-30?

Right now Castrol Edge Syntec European Formula SAE 0w-40 A3/B4. It is API SN, and a BMW long life-01 oil.
I was planning to use the 40 because of how hot it gets here in Texas, and it is readily available here (would have to amazon order the 0W-30). Nicely, I can use this in my wife's car as well. I will just need to let it warm up a bit in my car to reach optimum flow.
Of the many, many oil explanation threads, I like this one best:

On a good note, my M5 hasn't burned a drop of oil in 1800 miles. I think the 5500RPM and less break-in for the first 20 miles may have helped. I stayed in compliance with BMW's break-in rules, but still let it rev under demand through the first 4 gears right off from the Welt.
