Thanks for all the info.I have been running valvoline max life synthetic and a fram high mileage filter.Seems to be a lot of threads about older engine oils but nothing on the newer engines
I have been told the high mileage oils have more zinc and can burn up the cats.I think I switch over to the Mobil 1 and the wix or Mobil 1 filter.
