Ignition light

Would agree with above, needs a wee top up of oil. My oil light used to come on if i gave it a wee bit too much throttle from the off, but went out a couple of miles down the road. A wee top up and oil light stays off.
Sometimes an oil change can help if topping up dose not help.
If you do as darrsi explained you will probably see oil level in check window about half of window. So wee top up and see how it goes.
