so i was driving along the road and the oil light came on. ok so i drove back to my house and opened the bonnet to dip it for oil. it read that i was completely dry and as my car was heated up i opened the oil cap and obviously there was a bit of smoke from it. i put 2L into it and when i turned my car on again the light flashed up again although when i dipped it again it read that it was at good level? do i have to like reset the warning thing or what have you?
