Oil light flashes after driving for a while
First check that the oil level is appropriate. If the level is in the proper notch in the dipstick, you might have serious problems. Oil is heavy when cold, and produces acceptable pressure. When the oil warms up, it is less dense, and its ability to produce pressure is reduced. If during normal warm up and driving, the pressure drops below what is acceptable for the engine, the oil pressure light will come on, warning you that major engine damage is impending. Stop driving the car, and take it to a shop for inspection.
