So i was at my dealer today getting my oil change. They offer free lifetime oil change and they have this policy "100% engine life warranty." But that is only if you get all your maintenance done through them. So i'm at the 9000 mile mark and after i got it done, the tech guy says my upcoming oil change is almost at my 15,000k engine warranty maintenance which has oil, air cabin filter, radiator conidtioner, etc..... and its $200. Does anyone know if this is a good price or above average or average? Or is this guy trying to rip me off because the car dealership is trying to reel me in using their "100% ENGINE LIFE WARRANTY!" ?
