There is only one thing to do when you see an oil light on: stop driving.
Engine oil is what keeps your engine’s valves, pistons and rods in good working condition. Without that oil, your car can quickly turn into a bundle of junk with a large list of repairs attached to it. So when you see that light, pull off to the side. Stop driving, take your key out of the ignition.
Common reasons for this to happen:
Oil level is low
Your vehicle may be burning or leaking oil.
Oil pressure sensor is malfunctioning
This part measures the oil pressure in your vehicle. If it has become detached, dirty, or has broken, your oil light may stay on. If your car’s oil gauge isn’t showing any oil pressure even though the engine didn’t making any noises, this could be the cause.
Oil pump needs to be replaced
Especially on older vehicles, oil pumps can gradually wear out which will result in a lack of oil pressure. This loss of oil pressure usually happens when a vehicle is idling or at a stop light.
How important is this service?
Neglecting an oil pressure light could lead to severe engine damage, and must be attended to before driving further.
