Condition Based Service question

[thone35]

I noticed that my CBS miles never been changed. E.g. my oil change service is at the next 6000 miles, however, I has shown 6000 miles since the last 2000 miles. I wonder if this is normal for CBS? How do CBS miles change overtime?

Thank You

Yes and No, i.e. depends on how you drive, it adjusts constantly, and if you drive in a mellow way them maybe it adjusts in a way that keeps your remaining miles constant. In other words at first it assumed you needed your oil changed based on your initial driving but then figured your driving doesn't necessitate such an early oil change and adjusted.
