Oil pressure warning light
This warning light looks like a lamp with a drop of oil coming out of the end. But in some cars there is only a text saying just "OIL". This light comes on when the oil pressure of the engine has dropped to a low level.
The main function of engine oil is to lubricate the engine and reduce the friction. Thus it prevents excessive wear of engine parts while keeping the engine cool. It also cleans and engine and protects the engine from corrosion. Thus engine oil is very much important for a vehicle.
Running with low oil pressure can seize up or cause damage to the engine beyond repair.
Reasons for the oil pressure warning light.
- Not enough or worn-out oil
- Engine wear
- Faulty Oil Pressure Gauge
- Clogged or Dirty Air Filter
- High Oil Viscosity
- Engine Overheating
- Faulty Oil Pump
- Worn Out Internal Components
What to do next when the oil pressure warning light comes?
Turn your engine off and don't start again until you fix the problem. Engine oil helps to reduce the friction in moving parts in the engine while keeping those cool. Excessive friction in high temperatures can damage the engine in the worst way.
Check the engine oil levels. - Park the car on a leveled surface and let the engine cool down. Once the engine is cool enough, pull the engine oil dipstick and wipe it off with a clean cloth. Reinsert the dipstick and remove again. The level of oil will be marked at the end of the dipstick. If its too low, you need to top up with recommended oil type. You can find the type of engine oil in the owners manual.
Engine oil sensor faults can also bring up the engine oil pressure warning light. You can get a OBD 2 scanning to find any errors in the oil sensor.
If the oil pressure warning light is still on after topping up engine oils and the sensor is found to be working good, the problem would be in the engine oil pump. It is located at the bottom of the engine and you need to take the car to a garage to get it replaced.
