Just had a weird occurance earlier today. Dropped my g/f off to work, she was only going to be there for an hour or so. Parked the car and read a magazine for the next hour. Anyway started the car up, and the oil light comes on and the car gives me 4 beeps. Low oil? says I. I'd only checked it a couple of weeks ago. Stopped the car, popped the bonnet and checked the oil, and theres still plenty there. Started the car again, and the light is gone! Drove it round carefully for a while, didnt notice anything out of the ordinary. Should I be worried?

Nah.
