Thanks Jim,
I have been using mobil 1 truck and suv 5w30. do you know if the '06's are now being ok'ed to use the 5w20 (still under warranty)? Thanks for the info...I have used gtx in the past - great oil...good to know of the UOA's with gtx. It does get cold here, so that is why I really want a syn with a low pour point, but i guess what is really important is the UOA results. Thanks much
