They call for 5w20, 5w30, or 10w30 with 5w20 the car sounds very ticky and loud. With the 10w30 it was very smooth and quiet.
It's not very usefuls to generalize about oil grades when dealing with something subjective like engine noise.
I'd try some different oil chemistries before randomly going with an unnecessary heavier oil. For example I'd try a high moly oil like the Toyota 0W-20 or Subaru 0W-20. Many on this forum have found these oils to be very quite, myself included.
BTW, M1 0W-40 due to it's high VI (185) would actually be lighter on start-up at temp's as high as 80F to the Edge 10W-30 (VI 151). That's one reason why I consider any 10W-30 synthetic to be a waste of money vs the superior 5W-30 grade.
