I know that oil anecdotes are a dime a dozen... "runs smoother" after switching oils is a laughable cliche, and rightly so.
But I swear on anything that there is a real, true, noticeable, auditory difference between 5W20 Pennzoil Platinum and 5W20 Pennzoil Ultra Platinum in my 2016 Wrangler. For the ~5000 miles that my 3.L6 Pentastar had 5W20 Pennzoil Platinum in it I'd hear the lifters clatter for a few seconds at start up. After going to 5W20 Pennzoil Ultra Platinum the noise disappeared immediately.
I there that much of a difference between the oils? What could it be that eliminated the lifter clatter?
