Oil Pressure Low Stop Engine Comes On And Off (Causes And Solution)

Oil pressure is one of the most critical indicators of the health of your engine. It ensures that all of the moving parts in your engine are lubricated and functioning properly.

However, sometimes the warning light may come on and then go off again. This can be a confusing and potentially concerning situation for drivers. It’s important to understand the reasons why this may happen and what actions you should take if you experience this issue. 

In this article, we’ll dive into the causes of an oil pressure low warning and what you can do to prevent engine damage and keep your vehicle running smoothly.

Oil Pressure Low Stop Engine Comes On And Off

What Is Oil Pressure Low Stop Engine?

Oil pressure low stop engine is a warning message that appears on the dashboard of your vehicle. It happens when the oil pressure in the engine falls below the minimum level required for safe operation. 

The warning light is designed to alert you that the engine’s oil pressure has dropped. And that it’s necessary to take action to prevent serious damage to the engine.

The engine oil pressure is what lubricates and cools the engine components, and if the pressure drops too low, the engine can become damaged. If the warning light comes on and stays on, it’s important to stop the vehicle as soon as it is safe to do so. 

Symptoms Of Oil Pressure Low Stop Engine

The symptoms of low oil pressure can vary depending on the cause, but some common signs include the following:

Warning Light On The Dashboard

Warning Light On The Dashboard

If the “oil pressure low stop engine” warning light illuminates, it’s a clear indication that the oil pressure in the engine is low.

Engine Knocking Or Ticking Sounds

If the oil pressure is low, it may not be able to adequately lubricate the engine components. Thereby, causing them to rub against each other and produce a knocking or ticking sound.

Engine Stalling Or Misfiring

Low oil pressure can cause the engine to stall or misfire, as the oil is not able to reach all of the engine’s components.

Engine Damage

If the oil pressure is low for an extended period, it can lead to serious engine damage. This includes worn or damaged bearings, camshafts, and other components.

Causes Of Oil Pressure Low Stop Engine

When the oil pressure in your engine drops below a certain level, the “oil pressure low – stop engine” warning light will illuminate on your dashboard. This is caused by low level of oil, clogged oil filter, worn engine components, failing oil pump etc. 

This is caused by:

  • Low level of oil
  • Clogged oil filter
  • Worn engine components and
  • Failing fuel pump

Below is a detailed explanation of these causes and how to fix them.

Low Level Of Oil

If the oil level in the engine is too low, it may not be able to reach all of the engine’s components, causing a drop in oil pressure.

How To Fix It?

  • Top off the oil: If the oil level is low, simply adding oil to the engine may resolve the issue. It’s important to use the correct type of oil specified by the vehicle manufacturer.

Clogged Or Sealed Oil Filter

When the oil filter is clogged or sealed, it restricts the flow of oil through the engine, which can cause a drop in oil pressure. This is because the oil pump has to work harder to push oil through the clogged filter, resulting in a reduction in oil pressure.

How To Fix It?

Worn Engine Components

Worn engine components such as bearings, camshafts, and lifters can reduce oil pressure by increasing the amount of oil needed to lubricate the engine. Also, these worn parts can begin to leak oil, leading to loss of oil and causing a reduction in oil pressure. 

How To Fix It?

  • Replace worn engine components: If the oil pressure is low due to worn bearings or camshafts, they be replaced immediately.

Failing Oil Pump

If the oil pump is failing, it may not be able to properly circulate oil throughout the engine, leading to low oil pressure.

How To Fix It?

  • Replace the oil pump: If the oil pump is failing, it will need to be replaced to restore proper oil pressure. it can be a relatively expensive repair.

Leaking Oil Seals Or Gaskets

Leaks in the oil system, such as from a damaged oil seal or gasket, can cause a drop in oil pressure.

How To Fix It?

  • Repair oil leaks: If there are leaks in the oil system, such as damaged oil seals or gaskets, these will need to be repaired to restore proper oil pressure.

Clogged Oil Passages With Debris Or Sludge

Over time, debris and contaminants can accumulate in the engine’s oil passages, reducing the flow of oil and leading to low pressure.

How To Fix It?

  • Clean or replace the oil pickup: If debris or sludge is restricting oil flow, the oil pickup or passage may need to be disassembled and cleaned or replaced.

Faulty Oil Pressure Sensor

The oil pressure sensor is responsible for monitoring the oil pressure and sending a signal to the engine control unit. If the sensor is faulty, it may send incorrect readings to the ECU, leading to a false warning light. 

How to fix it?

  • Replacing the oil pressure sensor [our pick] is usually the solution for this issue.

Cost Of Fixing Oil Pressure Low Stop

The cost of fixing the issue will depend on the specific problem and the type of vehicle you have. On average, you can expect to pay between $200 and $1,000 for the repair, but it can be higher or lower depending on the circumstances.

You are suggested to go to a professional mechanic to diagnose the exact issue, and then he can give you a cost estimation. 

Engine Oil Pressure Maintenance Tips

There are several steps you can take to keep oil pressure high and maintain optimum engine performance:

Tip 1. Use The Right Oil 

Using the correct type and viscosity of oil for your engine is important for maintaining high oil pressure. Check your vehicle’s owner’s manual for the recommended oil type and viscosity.

Tip 2. Keep The Oil Clean 

Dirty oil can cause clogs and reduce oil pressure, leading to engine wear and damage. Regular oil changes can help keep the oil clean and prevent these issues.

Tip 3. Check And Replace Oil Filters

The oil filter is responsible for removing contaminants from the oil, and a clogged or dirty filter can reduce oil pressure. Regularly checking and replacing the oil filter can help maintain high oil pressure.

Tip 4. Monitor Oil Levels

Low oil levels can cause reduced oil pressure and lead to engine damage. Regularly check the oil level in your vehicle and add oil if necessary to maintain the correct level.

Tip 5. Avoid Short Trips

Driving short distances can cause the engine oil to not circulate properly, leading to reduced oil pressure and engine wear. Try to avoid short trips and take long drives instead to help maintain high oil pressure.


Let’s consider some questions people also ask about cars with low oil pressure and provide the necessary answers. 

Can I drive a car with oil pressure low?

It’s not recommended to drive a car with the “Oil Pressure Low – Stop Engine” warning light on, as it indicates that there is a problem with the oil pressure in the engine. 
Driving with low oil pressure can lead to serious damage to the engine and its components, such as bearings, camshafts, and crankshafts. In extreme cases, it can cause the engine to seize, resulting in costly repairs or even requiring a complete engine replacement.

How long will a car last with low oil pressure?

It can last about 14 days or 480 miles before it gets worse. But at this point, you may be faced with a serious repair or even replacement of damaged parts. 


Low oil pressure in a vehicle’s engine is a serious issue that can lead to significant engine damage if not addressed promptly. The warning light “oil pressure low stop engine” serves as a reminder to check the oil level and to have the vehicle inspected by a mechanic if necessary.  

However, to fix low oil pressure, a qualified mechanic will need to diagnose the specific cause. Also perform any necessary repairs, if need be. Regular engine maintenance and oil changes can help prevent low oil pressure and other engine problems.
