What is Engine Oil Pressure?
Engine oil pressure is the measure of the force exerted by the oil pump to push oil through the engine’s lubrication system. The oil pressure is typically measured in pounds per square inch (PSI) and is usually displayed on the dashboard as a gauge. The recommended oil pressure for most vehicles is between 30-60 PSI, although some vehicles may require higher or lower pressures.
What Causes the Engine Oil Pressure Light to Come On?
The engine oil pressure light can come on due to a variety of reasons, including:
Low Oil Level
One of the most common causes of the engine oil pressure light coming on is a low oil level. If the oil level in your engine is too low, the oil pump may not be able to generate enough pressure to properly lubricate the engine, causing the light to come on. It’s essential to check the oil level regularly and top it off as needed to prevent this issue.
How to Check Oil Level:
To check the oil level, follow these steps:
- Make sure the engine is turned off and the car is parked on a level surface.
- Locate the oil dipstick under the hood.
- Pull out the dipstick and wipe it clean with a rag.
- Insert the dipstick back into the oil reservoir and pull it out again.
- Check the oil level against the markings on the dipstick.
- If the level is low, add the recommended type and amount of oil.
Oil Pump Failure
The oil pump is responsible for generating the pressure needed to circulate oil throughout the engine. If the oil pump fails, the engine oil pressure light will come on. Oil pump failure can be caused by worn-out seals, clogged oil passages, or excessive wear and tear.
Symptoms of Oil Pump Failure:
The symptoms of oil pump failure may include: (See Also: Will a Car Overheat Without Oil? What You Need to Know)
- Low oil pressure
- Oil leaks
- Engine noise or knocking
- Difficulty starting the engine
Clogged Oil Filter
A clogged oil filter can restrict oil flow and cause the engine oil pressure light to come on. The oil filter should be replaced every 5,000 to 7,500 miles or as recommended by the manufacturer.
Symptoms of a Clogged Oil Filter:
The symptoms of a clogged oil filter may include:
- Low oil pressure
- Oil leaks
- Engine noise or knocking
- Difficulty starting the engine
Worn-Out Engine Bearings
Worn-out engine bearings can cause the engine oil pressure light to come on. Engine bearings are responsible for supporting the engine’s moving parts and should be replaced every 50,000 to 100,000 miles or as recommended by the manufacturer.
Symptoms of Worn-Out Engine Bearings:
The symptoms of worn-out engine bearings may include:
- Low oil pressure
- Engine noise or knocking
- Difficulty starting the engine
- Vibrations or shaking
What to Do if the Engine Oil Pressure Light Comes On?
If the engine oil pressure light comes on, it’s essential to take immediate action to prevent further damage to your engine. Here are some steps to follow:
Check the Oil Level
First, check the oil level to ensure it’s at the recommended level. If it’s low, add the recommended type and amount of oil.
Turn Off the Engine
