Every 15k for an oil change on an SUV? Isn't that a bit extreme? When I asked my mechanic about taking longer intervals to change oil using synthetic instead of non-synthetic, he told me that oil should be changed at normal intervals because it gets dirty. I use synthetic for easier starting in the winter (in my cars) and in my motorcycles because they turn at higher rpm's. But I never go longer than 3-5k intervals.
