My oil pressure light, and sometimes buzzer, are coming on when I go around a big turn like a highway exit ramp, or slow way down from 65 MPH.  I replaced the sensors to no avail. I dont know what grade oil I have but I will change that tommorrow, along with the filter which is currently BOSCHE. It otherwise runs ok, even during these oil light episodes. 

THere is an intermittent high pitched whistling noise that also appeared on the scene around the same time, and does not change in tone, pitch or volume with the speed of the car, or the engine, but only occurs at speeds over 50 MPH. It sounds like the noise brakes make when they are wearing in or out, but it never happens when I step on the brake. I'm not too freaked out by the noise like I am the oil light, but I include it here because it make be a clue. My mechanic thought it was the water pump and $360 later, the car still works the same.
