Will low oil cause overheating? Motor oil is an important part of any machine, it plays an important role in the operation and functionality of your vehicle, and an abnormal oil level can lead to severe issues in your car. Weather low oil can cause overheating, and how you can efficiently address such situations will be explained in detail in this article.

Purpose of motor oil: overview
Motor oil is one of the fundamental elements in your vehicle, its primary purpose is to lubricate all necessary parts of the vehicle. This engine oil serves as a cleaning agent in the vehicle’s engine, it removes all unwanted debris that can disrupt the car’s operation.
Frequent oil changes are vital responsibilities for automobile owners, it helps ensure that the car oil remains clean, effective, and free of impurities.
During car operation, some metal components generate friction, this increased friction generates more heat which can lead to the premature wear of these components, motor oil forms a layer between these components to reduce friction and guarantee an amazing engine performance.
The operation of the engine produces an immense amount of heat, this heat is absorbed as oil circulates, and the heat is then dissipated through the oil pan and cooling system. The primary reason for this distribution is to prevent the remaining oil from doing extra work and to maintain sufficient oil pressure.
Motor oil also forms a barrier on the engine’s components to prevent corrosion, oil contains additives that inhibit the oxidation of metal components, preventing them from corroding.
Signs of low oil pressure
- Burning smell. A burning smell in a vehicle is usually caused by an oil leak, and oil leaks are common scenarios that can lead to low oil pressure.
- Weird noises. Abnormal noises coming from your vehicle can be an indication that you have low pressure, check your oil immediately if you notice weird sounds you couldn’t hear before.
- Overheating. Engine oil provides lubrication for several engine parts and overheating is a sign that there isn’t enough oil in the engine.
Causes of low oil pressure
There are numerous causes of low oil pressure in a vehicle, these causes are explained below.
A damaged engine
Engine damage is a very likely cause of low oil pressure, malfunctioning parts can cause mechanical damage in the car engine, leading to low oil pressure.
Contaminants can also accelerate tear in car components and cause faulty engines.
Good oil helps in reducing friction, if there isn’t proper lubrication or if low-quality oil is used in your car, it can affect friction and ultimately lead to low oil pressure.
Cracks or fractures in the engine can cause an oil leak and a significant decrease in the oil level leading to a low oil pressure. Damaged components will certainly not function correctly causing inefficient circulation and compromising the sufficient oil pressure in your car.
Blocked or dirty oil filter
The oil filter is a very underrated part of a vehicle, it traps all substances that pose a threat to the internal components of your automobile. The filter traps all impurities present in the oil before they reach the components.
Checking the filter is equally vital as an oil change, if the oil filter is not checked regularly, unwanted substances will pile up on the surface of the filter affecting the oil line and disrupting proper oil flow.
The oil flow is affected when the filter is blocked, this will ultimately lead to a decrease in the oil level. If the filter is blocked for long, the pressure relief valves will let the oil bypass it and flow freely again, this can be very disastrous for your vehicle.
Some vehicles sometimes have a bypass valve installed in the oil filter, allowing unfiltered oil to flow through the engine during oil changes and decreasing oil pressure and contamination risk. You should check if your vehicle has this valve during your next oil change.
Coolant contamination
Contamination occurs when engine coolant infiltrates the oil system. The oil pressure might reduce when there is less barrier to flow from lower viscosity.
However, you shouldn’t have the impression that an oil with a higher viscosity is always safer.
The owner’s manual should contain detailed instructions on oil viscosity, if it is higher than the recommendation, it may cause resistance.
Low engine oil
External or internal oil leaks in your car can cause a decrease in the car’s oil level over time, some engines might consume more oil than usual due to improper installation or worn gaskets. Engines like this have a higher chance of having a low engine oil.
If an oil change is not made frequently it can deplete the engine oil supply and significantly affect oil levels. You should check your engine oil level during every oil change to prevent abnormal oil pressure levels.
Bad oil pump
The regular flow of oil throughout the system is controlled by the oil pump and low oil pressure might also occur when the oil pump is faulty and fails to operate normally.
A considerable drop in oil pressure is to be expected if it is unable to supply oil to the system.
What should you do if you have a low oil pressure?
Upon confirming the issue you should check for leaks and other possible issues in your car, if there are any deal with them swiftly, and if there are not you should replace the oil in your vehicle with a fresh one.
FAQ
Will adding oil stop overheating?
A low engine oil is a very common cause of overheating and adding oil to your car can stop overheating and prevent more complicated issues.
Can low oil cause overheating?
Yes, a low engine oil level can easily result in your engine overheating, you should check oil levels regularly to prevent scenarios like this.
What are the symptoms of low oil in a car?
