One of the best ways to maintain the smooth operation of your vehicle is through routine maintenance. It can be advantageous to keep some motor oil on hand for topping up your engine in between, even though an experienced professional should perform engine oil changes and tune-ups. How long can engine oil be stored, though? What location should you store it in? Continue reading for some of the most frequently asked questions about how to store engine oil securely and efficiently.

How Long Can Engine Oil Be Stored?

The shelf life of an unopened engine, transmission, hydraulic, and similar oils ranges from 3 to 5 years. Before using stored oil in your car, it's crucial to double-check the use-by date or date of manufacture printed on the container because shelf life can vary by product. To make it simpler to find, write this date in a permanent marker on the label. Remember that the shelf life of engine oil is significantly influenced by storage factors like location, temperature, exposure to direct sunlight, humidity, and whether the product has ever been opened.

What Location Should You Store Engine Oil In?

Engine oil may undergo thermal breakdown when exposed to direct sunlight, which lowers the thickness or viscosity of the oil. Heat-damaged oil, if used, may harm the engine of the car. Avoid storing oil in an area that experiences extreme heat or cold because both can change the viscosity of the oil. Additionally, avoid enclosed areas with little airflow because oxidation can be brought on by moisture and humidity. Store engine oil away from direct sunlight in a dry, temperate environment to avoid oxidation and other types of damage.

How to Store Used Motor Oil or Leftover Oil?

Engine oil's lifespan is reduced after it is opened by air moisture, which, as we previously learned, can lead to oxidation. Therefore, it is advised that after opening, use all of the engine oil. Here's how to store used motor oil or leftover oil, though, if it can't be used right away. Make sure the oil is stored in a container that is tightly sealed, preferably the original one, and that it is kept out of the sun's direct line of sight. Before using the oil in your vehicle, carefully check for any issues like discolouration, a change in viscosity, or the presence of foreign substances when re-opening the product.

Rules for Proper Engine Oil Storage

Both mineral and synthetic engine oil must be kept in a tightly sealed container and stored away from direct sunlight in an area that is cool, dry, and well-ventilated. Although both products can be stored, mineral oil typically has a shorter shelf life than synthetic oil.

Although proper engine oil storage is crucial for preserving the product's integrity, it need not be difficult. Just adhere to the following important rules: 

Keep in mind that engine oil is toxic and should not be thrown in the trash or dumped down the toilet. Dropping off engine oil at your neighbourhood waste management facility or reputable auto shop is essential.
