what happens when your oil light blinks and
you have oil in your car but then it quits
At lower RPMs the engine isn't pumping oil as fast as it does at higher speeds. On older cars, or higher mileage cars, you can experience very low oil pressure at around idle speed. Could be a defective oil pump or relief valve, or worn bearings. a blinking oil light indicates a serious problem and hyou should have a mechanic diagnose this VERY soon.
