Re: Burning oil in my 2009 Silverado

i know the fram filter sucks compared to others. I have a 07 Tahoe LTZ that has 139k on it and it used 2qts every 6k miles until i went to purolator filter which dropped back to 1 qt loss. the oil i always use is Mobil 1 full synthetic 5w-30. i only change oil until 10% left per the vehicle computer.
