Attached is a UOA of the Equinox I just sold. Miles were put on almost entirely on a 5 day (2 days down and 2 days back) round trip from central Michigan to Phoenix AZ. Oil used was Mobil1 0W-30 AFE and 1/2 quart of Mobil1 EP 0W-20 just to get it to the full mark. I know the owners manual recommends 0W-20 but that's what I had at the time.
Enjoy!
Enjoy!
