Are you looking for ways to transport gas? The question ‘Can you put gas in a plastic bottle?’ has probably crossed your mind. Putting gas in a plastic bottle may seem harmless. But is it? Putting gas in unapproved plastic bottles is unsafe.  It is also unsafe to fill gas in old glass or metal containers.

Some types of plastic can dissolve in gasoline because of their similar chemical structures. The hydrocarbons in gasoline can freely interact with those in plastic containers.  If the interaction between the plastic and gasoline is less energetic than the bonds in the plastic bottle, that plastic bottle will dissolve. You would be wise to keep a gas can in your car for your safety.

When You Put Gas in a Plastic Bottle?

Put Gas in a Plastic Bottle

Different types of plastic react differently to gas. Some may get brittle with age as they aren’t compatible with gasoline. They may be unable to withstand expansion and contraction from pressure and temperature changes. In addition, some plastic gas containers don’t seal well. There is the danger of fumes and spills causing accidents.

Avoid putting gas in anti-freeze jugs and glass containers. When choosing gas cans, opt for options with durable material

Can You Put Gasoline In a Milk Jug?

Milk jugs have a few thin threads to hold the cap on. While they are strong enough to hold your milk or water, you shouldn’t use them to store gasoline. The volatile nature of gasoline makes it inappropriate to put in a milk jug.  The liquid is volatile and it emits a lot of fumes. It could be explosively flammable.

If you put gas in a sealed plastic container, it could last three to five months. If you add a fuel stabilizer, it could last up to eight months. Ideally, you shouldn’t leave it for over a year.

While gas won’t necessarily melt your milk jug or plastic container, it could make it brittle.

Things You Shouldn’t Put In Your Gas Tank

Sugar and sticky liquids could damage your gas tank. Pancake syrup, honey, waffle syrup, and molasses can block the fuel filter. Coke and other soft drinks could also block your engine. Other things to put away from your gas tank include salt, bleach, urine, and water.

Where to Store Your Gas Tank?

Store your gas tank away from children’s reach. Keep it in a shed or garage away from direct sunlight. The gas tank should be on concrete with a piece of plywood beneath it.

Frequently Asked Questions

What kind of plastic can you put gas in?

High-density polyethylene (HDPE) plastics are ideal for making plastic barrels and can. They are durable and can insulate contents from heat changes in the environment.

How long does gasoline last in a plastic bottle?

Over time, gasoline will degrade and lose its combustibility. In a sealed plastic bottle, gasoline can last three to six months. It could last longer if you add a fuel stabilizer.

Can you put gasoline in a plastic water bottle?

You shouldn’t put gasoline in a plastic water bottle. Even though the bottle won’t melt, it could get brittle over time. Improper sealing could also allow fumes to escape. 

Can you put gas in a 2-liter bottle?

Yes, you can put gas in a 2-liter bottle. However, it isn’t safe. Accidental spills could cause significant damage. Some kinds of plastic will dissolve.


Are you trying to get some gasoline fast? The question ‘Can you put gas in a plastic bottle?’ has probably crossed your mind.  There are different types of plastic.
