I did search for the info I needed but I still have a question.

I changed my oil about 1800 miles ago, I use Mobile 1 & I do mostly highway driving. There's no way I need an oil change.

The formula it uses to determine that it's time to put the light on is based on the driving that's happened since the last time the light was reset, right? Let me rephrase that...It doesn't know (or care) that I've been changing the oil behind it's back so the light is not relevant to my oil changes, it's only relevant to my driving habits since the last light. Is my understanding of how this works correct?
