'03 Chevy Trailblazer service manual says engine oil change light will come on automatically. Apparently they have system that keeps track of how often/long engine is run. Last time I bought new car is about 6 or 7 years ago, and this is new to me.
My immediate feel was you gotta be kidding. I hard for me to trust on these automated engine oil change stuff.
My question: for those who have similar vehicle or similar engine oil change warning system, care to share your story as far as engine oil change goes? Like, what is your average driving and how often engine change light comes on? Do you feel it's reliable eough?
