Ok. So I changed the oil with synthetic. I used Castrol Syntec 5w30 and a Mobil 1 filter. So, my question is how long can I go until the next oil change. I am assuming that I can't go past 7500 due to warranty issues (I only have 23k on it so far). Also, since this is the first (I think since it was an Enterprise Rent a Car in it's former life) synthetic change, do I need to do it at 3k. Forgive me for all the questions, but this is my first foray into synthetics.
