I read a post a while back 10W-30 oil ran quieter and better. I ran 5W-20, then 5W-30 Winter and 5W-40 Summer as it's pretty hot down here in the South.
I ran 3,000 miles with 10W-30. Yes, it runs a bit quieter and seems smoother, but my GT felt like lost power. Just changed oil and filter and now running 5W-40 (for the Summer) and I can feel the difference. The exhilarating acceleration is back and feel the power of 5.0L GT. The get up and go is awesome with any of the 5W-xx weight, but not with 10W-30.
