Oil & Filter had 5100 miles. OLM = 51% remaining.
07 Denali w/6.2L L92 w/195k miles
Use is 70% hwy (18+ mpg) and 30% local/rural (15 mpg)
Oil was a mix of the two (see pic).
Engine didn't need any makeup.
Catch can caught 2 ounces in this 5k mile oil change interval.
Filter has some carbon in the bottom of the pleats.
The Valvoline "RESTORE" oil is no longer available but I have a stash of it. Its designed to "CLEAN". The insides of this ole engine needs cleaning. It had been road hard and hungup wet before I bought it 65K miles ago.
