Car dealers (at least here) dont really mind if you have your oil done somewhere (even the cheapest gas station service) as long as you use their recommended oil and they will still honor your engine warranty. So for me, i would rather do it somewhere cheaper using the recommended oil (in my case, Mobil 1) than paying the dealer to do it (thing is, my service is free, including oil change. LOL)
