Cars require frequent inspection and servicing. As a responsible vehicle owner and motorist, you must be observant with your car’s functioning and performance to avoid accidents and expensive repairs in the future. Recent technological advancements in the automotive industry have made it easier for us to detect whether our car is dealing with a problem. For instance, lights and sensors may tell us that there are problems in specific parts that require speedy resolution. One of the most common issues with cars is low pressure oil. We must have a basic understanding about this specific issue; its causes, symptoms, and how to apply quick fixes as soon as you see its light blinking on your dashboard.
It Pays to Understand Your Vehicle’s Car Oil System
Your car’s engine consists of various moving parts that rub against each other at high speeds. To reduce friction, a thin film is pressurized, which in turn helps in lubricating your vehicle’s various components. The pressure is produced by an oil pump that is connected to the engine. Besides that, oil also helps in cooling the engine and protecting its various metal parts. Typically, the pressure threshold may vary depending on whether your vehicle is at a full stop or moving. However, if the minimum value is not reached, the oil pressure sensor will light up which is then displayed as a warning signal on the dashboard.
The Most Common Signs and Symptoms of Low Engine Oil Pressure
Oil Warning Light
If the oil pressure drops below the ideal level, the sensor will automatically activate the oil warning light on the dashboard. When you see it light up, it is best to park at a safe place to pull over, such as at a petrol station, parking lot, or service station. You may then proceed and check your oil level. If the oil level is at an adequate level, it may be best to have your vehicle towed or repaired as soon as possible. A faulty oil pressure sensor can lead to a larger problem when you delay obtaining the necessary repairs.
Reduced Engine Performance
If your car suddenly loses power, stalls, or burns through a full tank faster than normal, you may be dealing with diminishing engine performance. While this drop may also indicate other car issues, one of its most common causes is low engine oil pressure. In this case, it is recommended to start small and inspect the oil level, to see if you need a simple change in oil, filter, or both.
Burning Oil Smell
The smell of burning oil can cause leaking oil, or the oil may be in contact with a hot surface in one or more components of your car. Burning oil smell typically indicates oil leakage which can lead to reduced oil pressure. If you are smelling burning oil while on the road, make sure to stop at the nearest petrol station or parking lot to check your oil level.
Unusual Engine Noise
When your engine is running low on oil, its components may be low on lubrication. When the engine is low on lubrication, you will notice the sudden appearance of unusual noises, such as knocking, ticking, grinding, and clunking emanating from the engine. In this case, it is best to take your car to your preferred auto mechanic shop in Sydney.
Overheating Engine
Engine oil offers much-needed lubrication to various parts of the car’s engine. Without the right amount of oil pressure, your engine will operate at decreased lubrication and increased friction that can generate heat in the process. Engine overheating is a complicated issue, as it may not point to low engine oil pressure right away. However, if the cause of engine overheating is low oil pressure, you may need to replace some components of your engine.
The Top Causes of Low Oil Pressure
- Malfunctioning Sensor
It is recommended to routinely check the low oil pressure sensor before you inspect and diagnose your car. If the sensor is not working properly in the first place, you are sure to end up reading inaccurate oil pressure levels. The warning light may suddenly turn on even when there is no problem with your engine.
- Oil Pump Failure
The main job of the oil pump is to generate enough pressure, ensuring the oil smoothly moves through various parts of the car’s engine. It carries oil in the pan and directs it to the engine block and cylinder head. When your oil pump fails as a result of old age and other external reasons, it facilitates the entry of bubbles into the oil, resulting in reduced pressure.
- Improper Engine Grade Oil
When buying engine oil, it is best to follow the specifications recommended by your vehicle manufacturer. Oil engine types may vary based on density, viscosity, and time as it breaks down, resulting in reduced lubricating capacity. If the engine oil has turned black, it is best to change it as soon as possible.
Other possible causes of low oil pressure are:
- Oil leaks in the engine
- Low oil levels
- Blocked oil strainer
Regardless of the cause and symptoms that you experience, you must be quick to react and perform the necessary quick fixes on your vehicle.
