I just get the Mobil 1 0w40 FS European car formula since its easy to source from Walmart here and the Mann filter every time. I live in southern california and it NEVER gets below 45F here, therefore I don't really need a 0 weight oil, but I do like that in theory it should flow slightly better when cold. In reality it probably doesn't make that big of a difference depending on your weather.
Like others have said, just go with a good quality oil that is 5w30, 0w40, or 5w40 and don't worry too much about it.
Some brands that make an appearence here on the regular are(in no particular oil):
Mobil 1
Motul
Genuine BMW
Castrol euro
Liqui Moly
Ravenol
Pennzoil Platinum
Any of those should protect your engine just fine. I actually had to send my wife to the store to pickup oil for me once... she got the Valvoline Euro 5w40 formula... guess what, engine was still fine
I think the most important thing here is to not beat on your engine until it comes up to temp. I personally don't really get on it until engine oil temps are above 180F.
