Can I store engine oil cans outdoors?
May 20, 2025
As an engine oil can supplier, I often get asked this question: "Can I store engine oil cans outdoors?" It's a valid concern, especially for those who have limited indoor storage space or are looking to free up some room in their garages. So, let's dive right into it and explore the ins and outs of outdoor engine oil can storage.

Factors to Consider
Before you decide to stash your engine oil cans outside, there are a few key factors you need to take into account. These factors can significantly impact the quality and safety of the stored oil and the cans themselves.
Temperature Fluctuations
One of the biggest challenges of outdoor storage is dealing with temperature fluctuations. Engine oil is sensitive to extreme temperatures. In hot weather, the oil can expand, which might cause the cans to bulge or even leak if the pressure becomes too much. On the flip side, in cold temperatures, the oil can thicken, which could affect its performance when you eventually use it.
For example, if you live in an area with scorching summers, the high temperatures can break down the oil's additives, reducing its ability to lubricate and protect your engine. And during freezing winters, thickened oil might not flow properly through your engine, leading to increased wear and tear.
Moisture and Rust
Moisture is another enemy of engine oil cans stored outdoors. Rain, snow, and even high humidity can cause the metal cans to rust. Rust not only looks bad but can also compromise the integrity of the can. A rusted can is more likely to develop holes or leaks, which can lead to oil spills and contamination.
Imagine finding a rusted engine oil can in your yard, with oil seeping out onto the ground. Not only is it a waste of oil, but it can also be harmful to the environment.
Sunlight Exposure
Prolonged exposure to sunlight can also have a negative impact on engine oil. The UV rays can break down the oil's chemical structure, causing it to oxidize. Oxidized oil loses its lubricating properties and can form sludge, which can clog your engine's filters and passages.
So, if you're thinking of leaving your engine oil cans out in the open where they'll be exposed to direct sunlight all day, think again.
Pros and Cons of Outdoor Storage
Now that we've covered the factors to consider, let's weigh the pros and cons of storing engine oil cans outdoors.
Pros
- Space Saving: If you have limited indoor space, outdoor storage can be a great solution. You can free up room in your garage or shed for other important items.
- Convenience: If you use engine oil regularly for your vehicles or equipment, having the cans stored outside can make it easier to access them when you need them.
Cons
- Risk of Damage: As we've discussed, outdoor storage exposes the cans to temperature fluctuations, moisture, and sunlight, which can damage the cans and the oil inside.
- Safety Concerns: Oil spills from damaged cans can be a safety hazard, especially if they occur near flammable materials or in areas where people or animals might come into contact with them.
Best Practices for Outdoor Storage
If you decide that outdoor storage is your only option, there are some best practices you can follow to minimize the risks.
Use a Storage Container
Invest in a sturdy storage container that can protect the engine oil cans from the elements. A plastic storage bin with a tight - fitting lid can work well. Make sure the container is placed on a level surface and is elevated slightly off the ground to prevent water from pooling around it.
Choose a Sheltered Location
Find a location that is sheltered from direct sunlight, rain, and snow. A covered porch, carport, or under a tree can be good options. Avoid areas that are prone to flooding or where water might accumulate.
Check the Cans Regularly
Make it a habit to check the engine oil cans regularly for signs of damage, such as rust, dents, or leaks. If you notice any issues, transfer the oil to a new can as soon as possible.
