First oil change on my 2016 Sierra was around 6000 miles and it still had 22% left on the OLM, so would have hit 0% around 7700 miles, or ~77 miles per percentage point. That was with a 20 minute commute one way that consisted of five miles of 55-70MPH freeway then 15 miles of ~45MPH two lane roads, in addition to whatever short trips I took around home and some more mixed two-lane driving for work.
With my new job my commute is 3.5 miles one way, temp gauge is usually just hitting 210º as I'm pulling into work's parking lot so far this winter. Oil change I'm on now has 508 miles and already dropped 10%, or 50.8 miles per percentage point. So I'll get slightly over 5K on this change per the monitor if it stays consistent. I'll probably pull it at 4K and send it to Amsoil/Oil Analyzers for a good look at fuel and go from there.
As for what kind of oil... I might go back and use the ACDelco full synthetic again if I happen to have a need for a Rockauto order where I can bundle the shipping. Failing that I'm not picky and it will probably come down to price, current fill is Napa 0W20 because it was $4/quart. When the warranty is up depending how everything looks I might consider going to a different grade or just stick with what's currently working. Heck I still have two five quart jugs of Mobil1 5W-20 and one Supertech 5W-20 in the garage that were for my Hemi Ram and my folks' 3.6L Charger before we both traded in and bought newer/new trucks taking 0W20.
