SIDE NOTE: The last time I took my 2015 Denali for an oil change, i inquired about the Oil Life display. The technician at the dealership told me that this particular display is more on the "Fancy" side of information than a reliable guide for oil change. He said that I could drive this vehicle on the Interstate for 80-100 miles and the display would show about 90-95% of life left; whereas if I drove it in the city, with all the stop and go, it would start showing 80-85%.... So, simply put, he suggested I'd follow the next recommended oil change mileage / date versus the oil life indicator....
