Should You Change Oil If Car Has Been Sitting: Ultimate Guide
Yes, you should change the oil if your car has been sitting for too long. Sitting for too long can be worse for your oil composition than driving, as oil rapidly loses its cooling and lubrication properties when left dormant.
Contrary to popular belief, oil can also become dirty from dirt, dust, and moisture even when the car is not being used. Therefore, it is important to change the oil to maintain the overall health and performance of your car’s engine.
How Long Is Oil Good In A Car That Has Been Sitting?
Oil that has been sitting in a car for an extended period of time should be changed. While the shelf life of unused motor oil is between five and eight years, it is important to note that the actual lifespan of oil inside an unused engine is only about six months.
Old oil can dry out and lose its ability to effectively lubricate the engine. Therefore, it is crucial to change the oil if the car has been sitting for an extended period of time, as sitting for too long can be detrimental to the oil’s composition and its ability to properly cool and lubricate the engine.
Waiting for the next interval to change the oil is not recommended, as the oil could potentially become ineffective if left sitting for too long.
How Long Can Oil Sit In An Engine?
Oil sitting unused in a car engine should not be left for more than six months. Synthetic oil is known to hold up better and can last for more miles compared to traditional oil. However, it is important not to extend oil changes beyond the recommended time interval set by the manufacturer, typically six months or a year for engines that are not driven frequently or on short trips.
Even though the shelf life of unused motor oil can be between five to eight years, the actual lifespan of oil inside an unused engine is about six months. This is because old oil can dry out, losing its ability to lubricate the engine effectively.
Therefore, it is necessary to change the oil if the car has been sitting for an extended period of time.
Does Oil Go Bad Sitting In An Engine?
Sitting for too long can be worse for your oil composition than driving. Oil rapidly loses its cooling and lubrication properties when left dormant. Contrary to popular belief, simply not using your car doesn’t mean the oil remains in perfect condition.
In fact, oil that sits for too long can actually become diluted with moisture and contaminants, causing it to break down and lose its effectiveness. While the shelf life of unused motor oil may be between five and eight years, the actual lifespan of oil inside an unused engine is around six months.
This is why it is recommended to change the oil regularly, even if your car has been sitting idle for an extended period of time. Regular oil changes ensure that your engine remains properly lubricated and protected, extending its lifespan and preventing costly repairs down the line.

Conclusion
It is important to change the oil in your car if it has been sitting for an extended period of time. Contrary to popular belief, sitting for too long can be worse for your oil composition than driving. Oil rapidly loses its cooling and lubrication properties when left dormant.
While the shelf life of unused motor oil is between five and eight years, the actual lifespan of motor oil inside an unused engine is only about six months. Old oil can dry out, and dry oil cannot effectively lubricate your engine, potentially causing damage.
Even if you haven’t put any miles on your car, it is still necessary to change the oil. Dirt, dust, and moisture can still contaminate the engine oil, making it less effective. Therefore, it is recommended to follow the manufacturer’s time interval for oil changes, typically six months or a year, especially if the car is not driven frequently or only used for short trips.
