I have had my car for about 2 years now, bought it at around 50k miles and currently have 65k. It is a 2009 4.6 with tech package. So far I have just done 2 oil changes with Mobil 1 Synthetic oil changes. Somewhat expensive around $70. I have not done anything else to the car other than these and when I bought it, the dealership told me they changed the coolant and filters before I received it. Just wondering what else do you guys do every 1-5 years?
