Oil pressure gauge -> ignition cut off?

[jondee86]

The oil warning light is a pressure operated switch that takes the
place of the oil pressure gauge in more "sporting" model cars

It is sometimes considered to be an "Oil Low" light, since it usually
only starts to turn on when the oil level is so low that the pickup is
uncovered on hills or around corners

Shutting down a race car engine when the oil pressure drops is a
good idea. So is pushing in the clutch and pulling to the side of the
track But if you are leading the race and there is only half a
lap to go... maybe you don't want to ????
