Some oils damp noise better than others. The noisy ones don't lubricate less well, they just transmit sound better. Don't worry.
yeah, no worries. I always let the silverado run 3-5 min before i pull it out of the garage. no real point in hopping in and driving something thats been sitting for a week.
