Lighter oil will definitely help.

I had been using 10W-40 for many years and until recently switched to synthetic 5W-30.

With 10W-40, I always heard that noise before oil pressure was up after a cold start. Now with 5W-30 synthetic, the noise is gone.

I have always been afraid of the thin 5W-30 oil but I am now sold on this thin oil, only with synthetic, though.
