today my dad went to get an oil change for his nissan quest at the dealer. I was with him, and of course after being on this site I just have the urge to ask what oil and filter they use. They told me nissan filter and Quaker State Synthetic Blend. As I have never seen the oil before I came home and did a search on BITOG. Nothing came up for it. So what is this oil? Any good? Can it be compared to or exceed Pennzoil dino? thanks
