What Are Subaru Black Engine Oil Symptoms?

Subaru cars are known for their reliability and long lifespan, but like any vehicle, they require regular maintenance to keep them running smoothly. One common issue that Subaru owners may encounter is black engine oil. In this article, we will explore the symptoms and causes of this problem and provide tips on how to address it.

Symptoms of Subaru Black Engine Oil

The most obvious symptom of black engine oil is, of course, the color. If you notice that your Subaru’s oil is black instead of its usual amber color, it could indicate a problem. In addition to the color, there are several other symptoms to watch out for, including:

  • Poor Engine Performance: If your engine is struggling to perform as it usually does, it could be due to black engine oil. Over time, dirty oil can cause engine parts to wear out faster, leading to reduced performance.
  • Increased Oil Consumption: Black engine oil can cause your Subaru to burn through oil more quickly than usual. If you find yourself needing to add oil more frequently than before, it could be a sign that your engine oil needs to be changed.
  • Engine Noise: Dirty oil can cause your engine to make more noise than usual. If you hear knocking or ticking sounds coming from your engine, it’s important to have it checked out by a professional as soon as possible.

Causes of Subaru Black Engine Oil

There are several reasons why your Subaru’s engine oil may turn black, including:

  • Dirty Oil: Over time, engine oil can become contaminated with dirt, debris, and other particles. When this happens, the oil can turn black and lose its effectiveness.
  • Carbon Buildup: Carbon buildup can also cause engine oil to turn black. This occurs when fuel is not burned completely, leading to the formation of carbon deposits in the engine.
  • Overdue Oil Change: If you have gone too long without changing your engine oil, it can turn black and lose its ability to lubricate your engine effectively.

How To Address Subaru Black Engine Oil

If you notice any of the symptoms mentioned above or suspect that your Subaru’s engine oil has turned black, it’s important to take action right away. Here are some steps you can take to address the issue:

  • Change Your Engine Oil: The most effective way to address black engine oil is to change your Subaru’s engine oil. It’s recommended that you change your engine oil every 5,000 to 7,500 miles, depending on the make and model of your vehicle. This will ensure that your engine oil is clean and effective at lubricating your engine.
  • Check Your Air Filter: A dirty air filter can also contribute to black engine oil. Make sure to check and replace your air filter regularly to ensure that your engine is getting the air it needs to function properly.
  • Keep Your Engine Clean: Regular cleaning of your engine can help prevent the buildup of dirt and debris that can contribute to black engine oil. Use a degreaser and a soft brush to clean your engine and keep it free of contaminants.

In conclusion, Subaru black engine oil is a common issue that can be caused by dirty oil, carbon buildup, or overdue oil changes. If you notice any of the symptoms mentioned above, it’s important to take action right away to prevent further damage to your engine. By changing your engine oil regularly, checking your air filter, and keeping your engine clean, you can ensure that your Subaru stays running smoothly for years to come.
