Engine oil is crucial for giving engine parts the proper lubrication and preventing friction and overheating problems. So there’s a chance you’ll wonder if you can start the car without engine oil.

You might not have any engine oil left in your car or want to experiment if you can drive without it. It is not advised to drain the engine oil in either situation completely.

So, even though the car will start without oil, you can only drive for 30 minutes. After that, the lack of lubrication will likely cause the engine to fail. In this article, we will see what happens if you try to drive without engine oil.

What will happen if you drive without oil?

For the engine parts to be properly safe, good quality, and quantity, engine oil is crucial. There will be excessive friction and overheating in the engine if there is no oil.

The metal components will start to shed fragments as a result. Other moving components of the engine, like rod bearings, may also be harmed by these fragments. These metal parts also rub against one another, causing early engine wear and tear.

Let’s examine whether or not the vehicle will start without the engine oil

Will a Car Start Without Oil?

If the engine parts are not damaged, the car can still run without the engine oil. If this is your first time driving without engine oil, there is a good chance that your car will start, and you can drive it for a short while. 

But without lubrication, the engine parts will start to wear out. You might not be able to start the car the next time as a result of the engine completely failing and seizing up.

Oil safety kill switches are also built into some diesel and gasoline engines. If the engine oil is low or finished, this oil safety kill switch will automatically turn off the engine and prevent you from starting it.

How to detect no oil in the engine?

You must be aware of the engine’s oil level. Use a dipstick to check the oil level. Ensure to refuel the engine if you see no oil on the dipstick.

Other signs of a low or empty oil level in the engine include:

  1. The dashboard’s Low Oil Pressure Warning Light illuminates. If the engine oil is low on oil or is completely devoid of oil, the engine will have low oil pressure causing the oil light to turn on.
  2. The engine makes clunking, knocking, and grinding noises.
  3. Overheating is a symptom of low oil in the engine. Metal parts in the engine come into contact with one another if no oil is present.

How do you fix a car getting seized after no oil?

If you have been driving your car without oil, chances are that engine parts have been damaged. The only way to fix this is to replace the parts. However, some cars automatically seize the engine when the oil level is low. In that case, you should first check the engine oil level and fill it up. 

If the engine still does not start, it is possible that oil is not reaching the cylinder head. In that case, you should do the following:

  1. Remove the bolts that hold the engine together.
  2. Determine the location of the spark plug wells. They are located on the cylinder head’s top.
  3. Penetrate the oil to the cylinder head walls via the spark plug wells.
  4. Allow the oil to sit for a few hours to allow it to pass through the piston rings. Try starting the engine again.

FAQ’s on Will Car Start Without Oil

When there is no oil left in the engine, it will completely fail to start. Because there is no oil, the engine parts will deteriorate. The seized engine will not produce any smoke, fumes, or other symptoms. It will simply refuse to start until the damaged parts get fixed.


In conclusion, a smooth and safe drive depends greatly on the engine oil. If the car has no oil, it can still run for a short while, but the engine parts will experience wear and tear problems without oil. Eventually, the damage will become so severe that the engine will no longer function. 

It will be very expensive to repair the engine at that point. Running a car without oil can result in damage that can cost up to $2000. Therefore, it is best if you always keep your oil level in the tank above the MIN level. If you suspect an engine oil leak, call a mechanic immediately because it will most likely result in an engine with no oil.
