how to get water out of engine oil (2-Best Methods)


Contaminated engine oil that has been mixed with water or other substances can damage your automobile’s engine. Water in engine oil is harmful. It not only denaturalizes the oil but also takes away its ability to lubricate the engine parts. The removal of water from oil is a typical process. Here are practical solutions that will help you get water out of oil.

Step 1: (Collecting tools)

For this process, you need to collect a couple of things, including:

  • Plastic bottle with cap
  • Pushpins
  • Oil container or drain pan
  • A large bucket
  • Funnel

Step 2: (Making holes in the bottle cap)

Take a plastic bottle to collect the contaminated engine oil later. Make a couple of holes in the bottle’s cap. The holes can be made using pushpins.

Step 3: (Pour Contaminated oil into the bottle)

Pour all the contaminated oil into the plastic bottle using a funnel and close the cap tightly. Ensure that the bottle can hold up to 2 liters of fluid so that no other bottle will be necessary.

Step 4: (Turn the bottle over the bucket)

Adjust it upside-down onto the bucket after tightly closing the bottle’s lid. To avoid oil leakage from the cap side, ensure the cap is secured tightly.

Step 5: (Let the air out)

Using the same pushpins, make some more holes on the bottom side of the bottle. It is now the top side of the bucket, as the bottle is upside-down.

The cap holes on the opposite side allow air to come out from the bottle and create a steady fluid flow.

Step 6: (Gathering the water in the bucket)

Once the setup of the plastic bottle is done, the gravity will allow the water to gush out of the holes in the cap and into the bucket, as the water and oil do not mix naturally. So water will be at the bottom, while oil will be at the top.

Final step: (Pouring clean oil into a container)

Wait for all the water to separate from the oil and gather in the bucket. When there is no rest water, the engine oil will be seen leaking from the cap holes.

So, this was one of the most effortless methods to get out water from engine oil.

Method 2:

If you do not find the first method helpful, you can try this method. This method is also commonly used to make your engine oil clean. One good thing about this method is that it doesn’t require any unique materials for the process. You can directly get the water out from the oil without any hassle. Look at it. 

Step 1: (Open the drain plug)

At first, locate the drain plug on the oil pan and then place a container underneath it to collect dirty water and oil spillage. After that, remove the drain plug slowly and check if water comes out or not.

Step 2: (Let the water out)

Keep checking if the water and the oil have been separated or not. If it is entirely isolated and the water seems on the bottom, loosen the plug slightly. If you see the water draining out of the hole, continue removing the plug. The water will start gathering in the container.

Step 3: (Keep holding the plug)

Let all the water rush come out of the hole. This purpose is to avoid wasting engine oil if it suddenly comes out after the dirty water.

Step 4: (Pause the flow)

When you notice that oil is coming out, put the drain plug back in for a moment so that the rest water content can settle at the bottom.
