i got a free engine oil change on november for annual change, but my CBS still had few thousand miles left.
fast forward 2 month, i now have 2000miles left on my CBS, and my free maintenance was over just last month.
what do i have to do in this case? reset CBS? i know i don't have to change engine oil, but i also don't want to disrupt CBS. won't CBS kinda pointless in my case?
