I just aquired a 05 GT from a female at work. she always had oild changed at quick change shop and I am pretty sure she did it regular but I am sure she also used dino oil...and the sticker on the window says something to that effect.. I always used synthetic in my cars but because of the miles I am thinking I am going to have to run regular oil so what is recomended on a 4.6L with that kind of miles ? I dont think it has any leaks but I just got the car yesterday.
