Low Oil Light
I think like two quarts maybe? Definitely more than one. As long as you have oil pressure you will be fine. The oil pickup is so low you can have fine oil pressure with only two quarts, but hard turns, braking, and acceleration may starve the pump.
2 quarts or when your wires fray on the end of the sensor. which ever comes first. mine came on and off sparatically with no loss in oil. i had to replace the wires and conncetor to the sensor in the pan.
based on where the sensor is at on the pan you can tell it would come on when it was 2 quarts low like everone else is saying...its slightly higher than halfway from the bottom of your pan
