So I was driving my car home the other day and the oil light started flashing and a terrible beeping noise came from the dash. My first thought was the oil pump but now I think otherwise. I've continued to drive it like this for over a month now, the car still runs great, but after about 30 mins of driving, that beeping/alarm oil light thing goes off again. Any suggestions?
