I don't think @lapsio 's driving conditions are anywhere near needing a heavy racing oil and that it could be worse for the engine in cold weather. This was a mistake made by the guy running the service desk at his dealership. Wouldn't be the first bogus recommendation I've seen by a dealership service advisor.

I would recommend trying a 0w30 or 0w40 euro blend. But I also think you're better with a 0w20 in freezing conditions for cold starts and fuel economy!

@lapsio you should look at BMW M3 bearing failure from that engine running heavy weight oil; this video from savagegeese (former member here) gives a good idea of what you might need to run. His example is in northern climate. Check the video at 10:00.
