Maybe it is different in the 6 cylinder vehicles. I have it in two Tahoes (2007 and 2019) and a 2020 GM sportscar with the 6.2 V8. I cannot even tell when the engine transitions from 8 cylinders to 4 cylinders and back. The only way I know it is happening is the V4 and V8 indicator on the dashboard.
