Will Using a 0W-20 Oil Help Reduce Valve Noise During the Winter?

Using 0W-40 Motor Oil Instead of 5W-20
I have a 2004 Honda Accord 2.4L that I recently installed 0W-40 in although Honda recommends 5W-20. With regard to engineering tolerances, I'm skeptical that there could be much difference between Mer...
