It might seem like an inconvenience but it is important to take the time to find out what has caused your oil light to come one in your car. You may just be low on oil or you may have a more serious problem but ignoring the warning will only lead to further damage.
When the oil pressure warning light comes on in your vehicle, you should immediately investigate the cause.
You Will Need
* A safe place to stop
* An oil filter
* An auto mechanic
* Diagnostic check
Step 1: Stop driving the vehicle
Stop driving the vehicle when the oil pressure warning light comes on and pull over to a safe place. Failure to stop can cause serious mechanical damage to your car.
Step 2: Check the oil level
Check the oil level on the dipstick, making sure the level is in the proper range.
Step 3: Add oil
Add oil if the indicated level is too low. Make sure the oil conforms to the manufacturer's recommended viscosity.
If the engine is burning oil, adding oil will only temporarily turn off the oil light.
Step 4: Check the oil filter
Check the oil filter to see if it is plugged up with gunk. A clogged oil filter can also result in low oil pressure.
Step 5: Check for oil leaks
Observe whether the engine is leaking oil if the problem has still not been solved. If there is a leak, have an auto mechanic replace any problematic gaskets or oil seals.
Most leaky gaskets and seals can be replaced without major expense.
Step 6: Check the warning light
Have a mechanic check whether the warning light remains on after it's disconnected from the oil-sending unit. If the light remains on, there is probably a short in the warning light circuit.
Step 7: Take your vehicle to a mechanic for additional tests
Have the mechanic perform diagnostic tests if the oil light remains on. Other possible reasons include problems with the oil pump, rod and main bearing clearances, camshaft end play, or cam bearings and lifters.
