VQ35HR cold start noise?? Video inside

My 09 FX35 on a cold start in below freezing temps makes this weird knock like noise. It started noticing it when the temps dropped down to 18 degrees with 5 degree wind chills outside. I was wondering if its normal or not? I figured its normal because the cold weather temps outside making the oil thicker.

here is the cold start noise:

Notice at the end of the video it's gone away after the engine has warmed up. Motor oil is fine I replaced it a few weeks ago. All normal??
 
yea, its fine.. its just the engine oil viscocity is thicker because of the cold weather, once the oil warms up a little it thins up and flows smoother.. happens to all cars

That's why they say u really shouldn't drive right away when u start ur car in the cold.. U should let it warm up a little and then go
 
Yeah, sounds just like mine these past few days. Mobil 1.
