Water In Engine Oil: Do These 5 Things Immediately [2024]

Imagine you’re in a hurry to work and you decide to check your car before heading out. So you naturally check the coolant and engine oil level and consider filling it if it’s necessary. My friend, Luke has the same experience.

He was trying to pour the engine oil into the car, however, the bottle in his hand wasn’t engine oil; it was a bottle of water. He was in a rush and didn’t realize this difference.

Once he filled the car with water, the vehicle immediately started behaving erratically and Luke witnessed a significant drop in the car’s performance. He was also gearing strange noises from under the hood.

This incident was a good example of severe problems that need immediate attention.

Now read this article to realize whether you should do it in the same situation.

5 Immediate Actions to Take When You Detect Water in Engine Oil

infographic for 5 Immediate Actions to Take When You Detect Water in Engine Oil

1- Stop Using Your Vehicle Immediately

As soon as you realize there’s water in your engine oil, your first action should be to quit using your vehicle. Turn it off as soon as you can.

While the water in engine oil disrupts the lubrication of components you face problems like component wear, overheating, or even more severe issues. Stop driving your car to prevent further damage.

2- Check the Engine Oil Dipstick

Consider using a dipstick to check the engine oil. If the water has entered the system, you see a milky oil or an oil with an unusual appearance.

Once you do this check, you will confidently choose a solution for your problem.

3- Drain and Replace the ENGINE Oil

Once you diagnose the water in engine oil, you should ask a mechanic to drain the compromised oil completely and replace it with the correct engine oil. This can only be done by a professional mechanic. This is a necessary step while it directly affects the lubrication.

4- Inspect and Repair Engine Components

After replacing the compromised engine oil, it’s time to fully inspect the engine components, especially the ones that are vulnerable to a shortage of lubrication.

Consider checking bearings, seals, and cylinders for any damages and replacing them if needed. Keep in mind that caring for engine components plays a large role in engine prevention and its longevity.

Identifying the Signs of Water in Engine Oil

You should detect the water contamination in the engine immediately. Because if you don’t, you will face more serious, costly, catastrophic failures. The signs below happen when your engine oil is contaminated by water:

1- Milky or Cloudy Oil

The first and easiest way to detect water contamination is by checking its appearance. The normal color of an engine oil is amber or clear. Once it’s mixed with water, it gets a milky or Cloudy color.

You can sometimes see water drops on the dipstick. Detecting the water contamination in engine oil is not a complex task.

2- Unusual Noises from the Engine

Since a contaminated oil is unable to lubricate the engine’s components, the friction will be increased.  So you hear unusual knocking sounds, tapping sounds, or rumbling. The noises are more significant during starts or under loads.

They’re alarming you that the engine has lubrication problems and this leads to component wear and other potential damages like overheating.

3- White Smoke from the Exhaust

While smoke that exits the exhaust system is sometimes considered normal in cold starts. However, if persists, it’s an indicator of water contamination in engine oil.

It tells us that water gas entered the combustion chamber as a result of a breach in any of the engine’s internal components.

4- Engine Overheating

As water compromises engine oil’s ability to lubricate, the engine should work harder to produce more heat. As a result of this, you face overheating or high temperature of the engine. This is a sign of water entrance into the combustion chamber.

5- Decreased Engine Performance

If water is mixed with the engine oil, one of its indicators is a significant performance drop. It includes reduced power, rough idling, or delay in acceleration. All of these happen as a result of oil’s inability to lubricate and protect engine components.

6- Increased Oil Level

If you haven’t recently topped your oil but the oil level is higher than the full mark, you should search for its reason. Typically, it shows showing presence of another liquid like water. Consider checking it with a dipstick.

7- Corrosion and Rust Inside the Engine

By this time, water in engine oil increases the wear of engine components and corrosion. This incident happens as time passes and you can not detect it soon. However, a professional mechanic can detect it.

You can also check this:

8- Coolant Level Drop

If there isn’t any leak but the coolant level is dropped, perhaps the coolant is entering the engine oil. This is sometimes due to a more serious issue like a failing head gasket or cracked engine block.

You should address and detect these symptoms promptly to prevent costly repairs.

Consider heading to a help center to inspect your car as soon as you see these symptoms. A mechanic can detect the water entering the oil and provide solutions for you. By doing this, you can improve your engine’s performance and prevent further damage.
