2019 Chevy Trax LT AWD
I just changed the oil, and in < 1 week and 30 miles the DIC shows the oil life percentage down to 94%. WTF! I’ve put on 5,800 miles since I last changed it (displaying 19% life remaining). Does anybody know how the oil life percentage is calculated? Clearly it must be more that simply time and/or milage. I do know that the percentage decreases substantially when I usually let in idle after remote start(s) during the winter. But this time it decrease by 6% with no R/S and hardly any miles.
