Chainsaws, tillers, lawnmowers, and other lawn and garden equipment all require fuel, so many of us keep some on hand in case we need it. However, if gasoline is stored incorrectly, it can catch fire and worsen, eventually resulting in an explosive explosion. There is a risk of fire, which can be dangerous to you, your family, and others. As far as I know, plastic containers don’t keep fuel fresh. There are numerous containers that should not be used for storing or transporting gasoline, including glass jugs, antifreeze jugs, and gas cans. With time, some plastics will become brittle, and these containers are not safe to use with gas. Internal combustion engines require gasoline, a highly flammable liquid. Even a tiny spark, flame, or hot item can ignite the vapors of this liquid. One cup of gasoline vapor has the explosive force of five pounds of dynamite when properly combined with air. As a result, improper storage and handling of gasoline can present some risks. As a result, it’s critical that gas be stored properly. Because gas can pose a health hazard, especially for children, it is important to store it properly. In this article, we’ll examine how gasoline deteriorates over time when stored in a plastic tank. As a result, let’s get started now.

Can You Store Gasoline In Plastic Containers?

There are numerous containers that should not be used for storing or transporting gasoline, including glass jugs, antifreeze jugs, and gas cans. With time, some plastics will become brittle, and these containers are not safe to use with gas. Other containers lack the strength to sustain the expansion and contraction pressures that temperature fluctuations can produce. They should be avoided. Some containers are marketed as gas cans, but that doesn’t mean they can be sealed tightly enough to prevent leaks. Because of this, authorized safety cans are the finest containers for handling and transporting gasoline. Safety cans come in a variety of sizes and with a variety of valve opening methods for putting liquids in. Pouring can be sped up and spillage reduced by using funnel spouts. The price may be a little higher, but these are far safer and have a much longer lifespan than the inexpensive cans of a hardware store product. They have a list of prerequisites that must be met before continuing.

Does Gas Go Bad In A Plastic Container?

In general, when a pure gas degrades, its combustibility diminishes. It’s the result of three to six months of evaporation and oxidation. A sealed and labeled metal or plastic container would suffice. There is a short shelf life of roughly two months to three months for the ethanol and gasoline blend In ideal conditions, fuel-stabilized gasoline can last for up to three years. Within a month of being stored in a car tank, gas begins to degrade. An airtight container must be used to keep the gas line. The date of purchase and the date of storage should always be written on the container. It is imperative that you keep the gas at a low temperature and in a low-oxygen atmosphere.

If your gas is kept in a storage facility, it will be subjected to extreme temperatures and humidity. Increased flammability and the possibility for an explosion or fire can potentially be a result. So, having a fuel container with more than five gallons of petrol is never recommended or advised. Use a gasoline stabilizer additive if you have an automobile, piece of equipment or a machine with a tank that has been idle for an extended period of time.

How Long Can You Store Gasoline In A Plastic Container?

It’s admirable that you’re curious about how long your gas line will last. Fuel system components can be damaged if the gas does not have the potential to ignite the engine. You should also check the manufacturer’s rules on how long you can keep the gas in your tractor, mower, or other machine or equipment before utilizing it.

If you fill your engines with gas that has been sitting around for a long time, you could be voiding your warranty. Old gas, on the other hand, does not equal or is contaminated poor gas. A well-preserved gas can last for six months. Due to oxygen and oxidation, the flammability of gasoline diminishes over time, making it less useful. Additionally, the volatile components that make it up evaporate. Proper storage of gasoline can extend its shelf life by three to six months. An appropriately sized plastic or metal tank, as recommended by the local fire department, must have its contents clearly labeled and sealed. No more than five gallons should be used. Fuel stabilizers and gas purity both play a role in determining how long it lasts.

How Can You Tell If Gasoline Is Bad?

Stale or turpentine-like smells aren’t enough to identify if it’s bad. If the gas has been around for more than a few months and is still being treated as if it contains alcohol, it is no longer good. A clear test tube is available. Take a clear test tube and fill it with gas, then hold it up to the sun. Check to see whether there are any suspended or floating particles in it.

If so, you may be dealing with toxic gas. Try lighting a spoonful of gas on fire to see if it emits soot or flames. Soot marks indicate the presence of a toxic gas.

What Are The Risks Of Using Old Gasoline From Plastic Containers?

The brittleness of some plastics over time makes them incompatible with gasoline. When the temperature changes, some of the corners lose their strength, and they can’t withstand the pressure of expansion and contraction.


It’s a good thing to learn more about gasoline, and it’s vital to do so. It would be beneficial if you used good fuel rather than bad. It is possible to damage your vehicle or your machines if you use contaminated gas. Gas is not a renewable resource. For this reason, learning how to correctly store gasoline is a must.
