I'm currently using it in my 08 Jeep Liberty and am pleased with it. Very quiet, in fact the quietest of all the oils I've tried in it, which included Pennzoil Platinum 5w20, Mobil 1 0w20, and Amsoil 0W20. Sound is not very scientific, but if noise is an indication of parts making some kind of contact then quiet is good. I'm hoping to see Pennzoil Ultra 0W20 at some point, I'd like to give it a try.
