This on all GM vehicles that are equipped with it. A lot of engineering went into the computations that determinie when it comes on. Anyone still changing oil at 3000 mile intervals with modern oil and newer vehicles is throwing money and good oil out. Especially if you are using any kind of synthetic or synthetic blend oil. Even non synthetic oil will go longer than 3K miles today.
I use MS Excel to keep track of the maintenance on all of my vehicles, motorcycles, tractors, etc. Works fairly well

I keep the records in the back of my owners manuals and these stay in the glove box. I can quickly show someone every oil change.
