I have the same engine and dont find the TGMO to be quietest..my experience has the M1 AFE 0w20 keeps this thing the quietest..so maybe this is our own opinion based on how we hear things? I find TGMO to be one of the noisier oils.
I noticed Mobil 1 AFE 0w20 to be quieter in my 08 Liberty than Amsoil ASM 0W20, and Edge 0W20. Next OCI I will be using a 30 grade oil, probably either PU 5W30 or AFE 0W30 I have both in my stash.
I recently learned that Chrysler changed their position regarding viscosity for the 08 Liberty. They originally spec'd only 5W20 for the 2008-2012 Liberty, now they gave 5W30 the nod as well. So 30 grade it is!
