Ok so i own a 94 honda accord ex and yesterday when i was driving it the oil light started blinking. Immediatley i drove to the gas station and topped it off with about a quart of 5w-30. I started the car back up and the light was off. Later that night i was driving home and the light again came on and was blinking steadily. I dont see any leaks anywhere but its been raining alot and its hard to tell and the engine sounds the same as always no wierd noises or anything. Would this just be a sensor or sludge build up on the screen, or could it be a bad oil pump or switch. The car has 253,000 Miles on it. I believe it was rebuilt around 100k because of an oil problem and the engine siezed up which i believe the manufacture had a recall on. Is there any common problems with these cars that causes this oil light to blink?
