When a car is not driven for an extended period, the oil in the engine can degrade over time. Several factors can affect oil life in a car not driven, including:

Length of Time the Car Has Been Inactive

The length of time a car has been inactive is a critical factor that affects oil life. The longer the car sits without being driven, the more likely the oil will degrade and lose its lubrication properties. Typically, if a car is not driven for more than six months, the oil will start to break down, leading to potential engine problems.

Climate Conditions Where the Car Is Stored

The climate conditions where the car is stored can also impact oil life. If a car is stored in a damp or humid environment, moisture can accumulate in the engine, leading to potential oil contamination and degradation. On the other hand, if a car is stored in extremely hot or cold temperatures, the oil’s viscosity may change, affecting its lubrication properties.

Quality of the Oil Used in the Engine

The quality of the oil used in the engine is another crucial factor that affects oil life. High-quality oil with the right additives can last longer and provide better protection to the engine. Using low-quality oil or oil that doesn’t meet the manufacturer’s specifications can lead to premature oil degradation and potential engine problems.

Level of Oil in the Engine Before Storage

The level of oil in the engine before storage can also impact oil life. If the oil level is too low, the engine may not receive enough lubrication, leading to potential damage. Conversely, if the oil level is too high, it can cause the engine to overheat, leading to potential engine problems. Therefore, it’s essential to ensure that the oil level is at the manufacturer’s recommended level before storing the car.

Signs of Oil Degradation in a Car Not Driven

When a car sits idle for an extended period, the oil inside the engine can experience significant changes, leading to oil degradation. Here are some signs that indicate the oil in your car may degrade if it’s not driven for an extended period:

Changes in Oil Color and Viscosity

Over time, the oil in your car’s engine can change its color and viscosity, indicating a lack of proper lubrication. The oil may turn darker and thicker, indicating that it’s dirty and has lost its viscosity. This can lead to increased engine wear and tear, causing long-term damage to the engine.

Unpleasant Smells Coming from the Engine

If you notice a foul odor coming from your car’s engine, it could be a sign of oil degradation. The smell may resemble burnt oil or rotten eggs, indicating that the oil has broken down and needs replacing. These smells can also indicate other issues with the engine, such as a coolant leak or a blocked exhaust.

Engine Noise or Difficulty Starting

When the oil in an engine degrades, it can cause engine noises or difficulty starting the vehicle. The engine may make knocking or ticking sounds, indicating that the oil is not reaching all the engine’s parts, leading to increased friction. This can cause long-term damage to the engine. Additionally, the car may have difficulty starting, indicating that the oil has thickened and is unable to circulate correctly.

Steps to Maintain Oil Quality in a Car Not Driven

When storing your car for an extended period, it’s crucial to take steps to maintain the quality of the oil in your engine. By doing so, you can prevent oil degradation, extend the life of your engine, and save on costly repairs. Here are some steps you can take to maintain oil quality in a car not driven:

Changing the oil before storing the car

The first step to maintaining oil quality in a car not driven is to change the oil before storing it. Old oil can contain contaminants and moisture that can lead to oil degradation, even when the car is not in use. By changing the oil, you can remove these contaminants and ensure that your engine has fresh, clean oil when you’re ready to use it again.

Using high-quality oil and filters

Using high-quality oil and filters can also help maintain oil quality in a car not driven. High-quality oil has additives that can help reduce oil degradation, while filters can help remove contaminants from the oil. When choosing oil and filters, it’s essential to choose ones that are compatible with your car’s engine and recommended by the manufacturer.

Keeping the engine covered and protected from the elements

Keeping the engine covered and protected from the elements can also help maintain oil quality in a car not driven. Exposure to sunlight, moisture, and dust can accelerate oil degradation and lead to potential engine problems. By keeping the engine covered and protected, you can prevent these elements from affecting the oil’s quality.

Running the engine occasionally to prevent oil stagnation

Finally, running the engine occasionally can help prevent oil stagnation and maintain oil quality in a car not driven. When the engine is running, the oil circulates throughout the engine, preventing it from sitting in one place and degrading. However, it’s essential to follow the manufacturer’s recommendations and not overwork the engine during these occasional runs.

By following these steps, you can maintain oil quality in a car not driven and ensure that your engine is in good condition when you’re ready to use it again.
