Low Oil Pressure When Driving

Almost every motorist understands that engine(Motor) oil plays an important role in running your vehicle smoothly and efficiently. It lubricates all moving parts of the engine and reduces wear. However, low oil pressure negligence will permanently damage the engine within no time.  

This article provides information on low oil pressure symptoms, their causes, how to measure engine oil levels and more.

Symptoms of Low Oil Pressure

Engine oil pressure drops due to multiple reasons. Most cars are smart enough to identify rising issues, but your engine itself gives you signs that something is going wrong. Below are details that will guide you.

1. Illuminated Oil Pressure Light on the Dashboard

When you notice a low-pressure warning sign on your car dashboard, it means something regarding the oil level. In some cases, it blinks when the engine is idle or warm, which means the oil pressure sensor is probably faulty. But take it seriously; go through the other signs. If you are not sure, assist any mechanic. However, modern vehicles have safety features that shut down the engine when there is low oil Pressure.

2. Noise (Clunking sound) from the Engine

If the crankcase oil level is low, it may fail to provide adequate lubrication to critical parts, rubbing metal against metal. As a result, you will hear clunking, knocking, ticking, and grinding noises from the engine, and the engine temperature will also rise. 

You will immediately get professional help.

3. Overheated Engine

Engine oil provides lubrication to moving parts. If there is not sufficient oil pressure, your vehicle engine will run with decreased lubrication, whereas increased friction will cause heat. However, low oil pressure is not the only cause of overheating.

4. Burning Smell

If oil leaks on a hot surface or exhaust pipe, causing a burning smell, this could be a failed gasket or valve seal. It will reduce oil pressure, so it is better to take maintenance service.

Causes of Low Oil Pressure

If you see a warning light of low oil pressure, you can face a serious problem. Level, pressure, and the right type of oil are essential to running the engine optimally. If the engine runs continuously with an oil pressure drop, it will damage the engine in a few minutes.

Understanding the guidance below can help avoid expenses and additional headaches if the engine is seized. It provides Information about the importance of oil pressure, its causes, and the best strategy for an emergency.

1. Wrong type of Engine Oil (Incorrect Oil Viscosity)

If the wrong viscosity is specifically not recommended in the car’s owner manual, the low viscosity has less resistance to flow, hence the oil pressure drop; this will trigger the oil pressure indicator. Follow only manufacturer recommendation; higher viscosity creates resistance to flow and causes poor engine lubrication.

2. Irregular Oil Changes

It will occur when there is negligence in following the recommended oil change schedule because it’s normal that the oil level will decrease with vehicle usage.

3. Bad Oil Pump or Oil Pressure Sensor

If the engine does not have sufficient oil pressure, it could be an issue with the oil pump (wearing out). It will show an oil pressure light or a low-pressure gauge reading. If the oil pressure sensor malfunctions, it will appear as a false pressure reading. In both cases, vehicle services are concerned.

4. Oil Leak

As your vehicle ages, it is more susceptible to oil leaks, which can cause low oil pressure. It is better to diagnose the problem with a mechanic before fixing it.

5. Clogged Oil Filter

The oil filters are usually clogged due to dirty (overused) oil, which will reduce oil pressure.

6. Lack of Oil

Older cars evenly consume more oil with the passage of time because of the wearing of piston rings and other parts. This Lack of oil can damage your vehicle.

Conclusion

Maintaining proper oil pressure is essential for the life and performance of your engine. By recognizing the signs of low oil pressure and addressing issues promptly, you can prevent costly repairs and ensure the longevity of your vehicle’s engine.
