I've had my '05 X for a couple of months now. I have noticed that the oil pressure guage moves quite a bit. I will start my X and the needle is right in the middle where it should be. When I get to wherever I am going I look at the guage and the needle is right above the bottom line. It never goes outside the "normal" range but it gets really close. When I check my oil it is full.
Since it has not left the normal range I haven't called the dealer yet. Does this happen to anyone else?
