If you’ve ever wondered how long gasoline lasts in a can, this article is for you. The true answer to this question can vary, depending on the manufacturer and design of a can. However, most cans keep gasoline and other similar liquids stable at room temperature for at least three months before expiration.


Does Gasoline Expire?

Yes, gasoline does expire! That’s right, the gas you use to fill up your car or truck will go bad after a while. Why? Gasoline comprises a few different types of chemicals, including benzene and toluene. Heat, humidity, and oxygen directly impact stored fuel. 

Gasoline starts degrading and loses its combustibility due to evaporation and oxidation. If gasoline is stored in a sealed container (metal or plastic), it can last between three and six months.


What Is The Danger of Using Bad Gasoline?

There are many hazards of using expired gas in your vehicle. One of the biggest dangers is that it can cause a fire, which could lead to an explosion. Another danger is that it can damage your engine and cause it to fail or break down. This will ruin your car, which may require extensive repairs that may prove to be expensive.


What Is the Best Way To Store Gasoline and Make It Last Longer?

Gasoline is integral to our lives and helps fuel almost all vehicles. But how do you store gasoline and make it last as long as possible? The best way to keep your gasoline fresh is to store it in a cool, dry place. If you live in a humid climate or have water on your property, be sure to keep your gas container elevated so that they’re out of reach of any water sources.


How Can You Identify Old Gasoline?

Gasoline is a mixture of different hydrocarbons. It’s a byproduct of the refining process and can be dangerous if it has expired. Here are some ways you can tell if it’s old:

One of the easiest ways to identify old gasoline is by checking its color. Old gasoline will be brownish. You will also notice that gasoline’s scent changes as it ages. Stale gasoline will have a rancid smell, like turpentine or something similar. 

If you’re unsure whether the gasoline in your container has gotten old, it’s better to err on the side of caution and not use it. The following video will help shine clarity on how to identify bad gasoline.



Can You Mix Old Gasoline With New Gasoline?

It is possible to mix old gasoline with new gasoline; however, it’s not advisable. The reason for this is that there are some additives in the older fuel that break down into smaller, more volatile molecules when mixed with new gasoline. 

The amount of old gasoline you mix with new gasoline will also determine whether the mix will be usable. Even if you mix equal amounts of old and new gasoline, the two ages will mix and make it usable. You should, however, consult a professional before using mixed gasoline.


Can You Use Old Gasoline in Other Appliances, Such as Your Lawn Mower?

You cannot use old gasoline appliances such as a lawn mower as it will damage the internal parts.


How Do You Dispose of Expired Gasoline?

The best way to dispose of old gasoline is in government-approved containers with a secure lid. It is always best to reach out to local authorities when disposing of old gasoline. Depending on your area, you would need to take the gasoline to a waste disposal site for hazardous materials, the fire department, a recycling center, or even an auto parts store.

When disposing of gasoline at a waste disposal center, you should call ahead and check if they have any restrictions. Some centers offer a free service to citizens from specific areas. Others may be expected to pay a fee. 

Some centers also accept limited quantities per person in a single visit. It would help if you learned that limit before visiting the center. If you’re dropping off old gasoline at an auto repair shop, you should check if they accept the quantity accepted per person. Most shops accept gas for free; however, it is in limited quantity.
