Gasoline is so prevalent in our day to day lives that it’s easy to forget how hazardous of a compound it can be. Introducing gasoline into the environment can have severe consequences on wildlife. It can affect public health, too, if that gasoline ends up in drains and sewer systems. Knowing how to dispose of old gasoline safely is essential.

How to Dispose of Old Gasoline Mix

Different municipalities often have different rules when it comes to the disposal of harmful compounds like gasoline. Before you start, check with your local government to see if they have any specific regulations regarding how to dispose of old gas. Aside from regional variations, you can usually follow the steps below to dispose of your old gasoline:

Step 1:

Pour the gasoline into a clear container to check it before you dispose of it. If the gas was left outside, it might have been watered down. 

You don’t need to know how to dispose of gasoline with water because they will separate easily, with the gas rising to the top. Let it settle, then carefully pour the gas into another container. Pour the water that’s leftover through a rag. They will catch the last gas traces, making the remaining water safe to pour down the drain. Put the salvaged gasoline back into the engine.

Step 2:

If the gas is dirty or unusable, empty it into a disposable, gasoline-approved jug for transportation. You can use a funnel to make the pouring easier. Many disposal centers require you to leave the gas can along with the gas, so a cheaper disposable model is often an excellent way to go.

Step 3:

Determine where you can take the gas to recycle or dispose of it safely. You’ll usually have a few different options:

Recycling centers

Some municipalities offer gasoline recycling through their recycling centers. 

When this is the case, it’s typically restricted to a few centers or to a specific day or time of year. Check with your local government for specifics.

Hazardous waste centers

These are also government institutions. The main difference between these and recycling centers is that waste disposal centers don’t repurpose or recycle gasoline. Again, you want to be sure to call ahead, as some centers will only take gas at certain times, while others have a maximum amount they can accept in any given period. You may also need to pay for the disposal service, so be aware of that before you go.

Paid disposal service

You can find services that will come and pick up old gasoline right from your home in some areas. The fees for these services tend to be pretty steep, so it’s probably not worth it unless you have a lot of old gasoline you need to get rid of.

Community collection events

Some cities hold regular recycling events designed to encourage citizens to recycle. Check your local community events calendar to see if this is an option in your area, and when the next event will occur.

Local fire department

Some fire departments will dispose of old gasoline. If not, they’ll likely be able to tell you the best option for your region.

Auto garage

Mechanics already have many hazardous fluids to dispose of, like the old oil, transmission fluid, and other fluids they drain out of cars they service. Many shops will happily add your old gas to their waste for free. As with other services, call first to make sure this is something the shop offers before you show up with a gas can in hand.

Step 4:

If you cannot take the gas for recycling or disposal right away, secure the lid on the container and store it in a cool, dim place. 

Make sure it’s out of the reach of any kids or animals in the home—old gas doesn’t burn as readily, but it’s still not safe to drink. As long as the lid is secure, you can safely keep old gasoline in storage indefinitely, so there’s no rush if you can’t get to the disposal right away.

As you can see, it’s a pretty simple process. It all comes down to knowing your options and doing your homework to find out where you can take your old gas (and when). 

With a little digging, you should be able to find a way to dispose of it for free, even if your city doesn’t offer gasoline recycling.

Just as important as knowing how to dispose of gas correctly is knowing what not to do. We use gas so often that it’s easy to think of it as harmless, but it’s not something that you should handle lightly, even after it’s lost its combustibility to age. There are a few things you shouldn’t do when you have old gasoline:

  • Don’t throw old gas in the trash. Not only is this illegal, but it is also a potential hazard. Under the right conditions, even old gasoline can start or contribute to a fire.
  • Don’t pour old gasoline down the drain. Harmful chemicals like gasoline become a public health hazard when they enter the water system. This is aside from the damage they can do to the animals and plants around sewage drains. One gallon of gas can pollute as much as 750,000 gallons of water, so don’t delude yourself into thinking a little bit won’t do any harm.
  • Don’t store gas cans outdoors. Gas cans are durable, but the plastic models can be punctured, and metal cans are susceptible to rust. Leaving old gas outside makes it more likely the cans will leak and seep into the environment. If you don’t have a garage or basement, keep the gasoline in a closet or cabinet away from food. You can wrap it in a plastic bag if you’re worried about odours or leaks.

The penalty for illegally disposing of gas can be steep and can even include jail time as well as costly fines. Even if you don’t get caught, the toll on the environment can be steep. Disposing of old gasoline safely is worth the small amount of extra effort it entails.

How to Remove Gasoline from your Lawnmower

To maintain it properly, drain the gasoline from your lawnmower when you store it for a long time. In this article, I explain how to do it. Old gasoline is not suitable for the lawnmower. After two months, the particles settle, and the quality of the gas deteriorates. Therefore, it is essential not to leave the lawnmower full of gasoline in the shed all winter.

Siphon with two pipes and a rag

Follow the steps below to remove the gasoline from the lawn:
  • Make sure the engine has cooled down.
  • The gasoline is drained by gravity. So place the jerry can on the ground next to the stopper. The hose must always be lower than the gasoline level in the tank so that the gas continues to flow as soon as it has started to flow.
Now What Right?
  • Insert the hose into the tank until it reaches the tank’s bottom and is submerged in gasoline. To check if the long hose is submerged, gently blow into it. Do you hear bubbling? It is good! Place the other end of the long hose in the jerry can, and then place the short hose next to the long hose in the filler opening. Please do not push the short hose too profoundly; it must not be submerged.
  • Close the filling opening. Use an old rag and make sure that the air does not escape. Air escapes? In this case, wet the cloth, wring it out and try again. With a damp cloth, you can close the hole more easily. 
  • Blow air through the short hose. If you have an air compressor, you can let it blow for you; otherwise, you have to use your mouth. Make sure not to inhale gasoline fumes. By blowing through the hose, the gas tank’s air pressure increases and causes the gasoline to flow through the longer hose. Blow until gasoline flows into the jerry can. Stop blowing once the gas flows; gravity does the rest! Is the jerry can full, or do you want to stop the flow? Lift the hose or jerry can. Gasoline stops flowing above the gasoline level.
  • Once all the gas has run out, you are done draining. Remove the hoses from the fill opening and close the tank. Close the jerry can because of the gasoline fumes.
  • There is always some gasoline left in the engine. Move your lawnmower and let the engine run until all gas is gone.

Tips to Follow for Cleaning a Gas Tank

Tank scrubbing may seem overwhelming for beginners, but with a little experience, minimal effort, and some knowledge of mechanics, even an amateur can easily do it. Note that the procedures to be followed vary mainly depending on the size of the engine.

Tools needed to clean the engine

Before cleaning the gas tank, it is essential to ensure that you have all the necessary equipment.

How to Clean a Gas Tank

More comfortable to access, the fuel tank of a motorcycle, mower, or snow blower is easier to maintain. Its cleaning is done in only five steps:


The tank must be disconnected to facilitate its handling and optimize cleaning. To do this, you must:

  • Remove the bolts or fixing screws;
  • Remove the spark plug (if it is a lawnmower);
  • Open the tank cap as well as the drain valve;
  • Detach the other pipes that can be connected to the room to be cleaned.

To avoid the invasion of the lines by dust and to see the residual gasoline spilling into the carburettor, the fuel line should be sealed with a smooth-faced clamp, which should be fastened near the carburettor. It will then be necessary to lay the fuel line over a container before removing the clamp and emptying the contents.

To start cleaning, it is then essential to remove the rest of the fuel by pouring everything into a suitable container and collecting the rest with a suction pipe before letting it dry.

Once the tank is dry it is advisable to examine it and comb it with a fine comb to loosen imperfections such as traces of rust or other defects that require repair.


Wash the tank with a high-pressure sprayer to remove any deposits or build-up on the container’s bottom. Aim the spray bottle at all corners of the tank to optimize cleaning.

How to Recycle Oil


You can make traditional soap with it, a soap that works very well for washing clothes by hand or any other use. These are done with caustic soda and used olive oil.

The soda is dissolved in hot water, and the oil is added little by little, and it moves so that it thickens, producing saponification, and once a stiff paste is formed; it is left to rest and cut. It should be done with gloves because caustic soda is very corrosive.

Make Bio-diesel 

Biodiesel is a fuel used for diesel engines, but it is much less polluting since it is made from vegetable oil and not fossil fuels.  

Make an oil lamp or candle

  • We take a nice jar as a container—wire for the base of the wick and a cotton thread that protrudes from the jar. Aromatic plant essential oil can be added for scent as well. The process is straightforward: the wire wound in a spiral shape is placed in the center of the jar. The cotton string is tied to this wire protruding from the jar, the jar is filled with the used olive oil and the essential for flavouring, and the wick is lit that will consume the oil in the jar, giving light and aroma.
You can do the following a straightforward step by step. You only need a container, wire, thick string, and the oil you want to recycle:
  • Filter the oil very well, mainly if it was used for frying.
  • With the wire, make a joint for the wick (it is convenient to wrap the wire around a stick of the same approximate diameter as the thread, remove the stick and bend one end of the wire to act as a base).
  • Pass the thread through the joint. A few millimeters should protrude from one side; from the other, a longer piece.
  • We place the joint with the thread, which will be the candle’s wick, inside the container, and then we fill it with oil, letting the wick stick out.
Spreading cooking molds:

To make pastries and pastries, the molds are usually greased with fat to prevent it from sticking to the edges, well the used oil could be used here, and it does its job just as a new one, it is about preventing stick the product does not give flavor or aroma so that it would be worth it.

Protect wooden furniture: Olive oil has a great capacity to protect the wood, but we recommend using more for farm or garden table since olive oil gives off an odour that is not appreciated outside. At home, it can be something substantial. It is always used with a brush or brush on wood that is not varnished; this covers the pores and protects; if it is done every six months, you will have shiny outdoor furniture, and the wood will not suffer so much from the sun.

Lubrication of hinges and locks: it can help to lubricate oil parts of different machinery; it does not have to be mineral oil; it can be used olive oil. And you have to apply it on these gears so that they stop screaming and work more smoothly.

Homemade paintings

There are two ways to recycle oil into the paint. One of them is to look for recipes for homemade paints that have it as a component. 

Make homemade moisturizer

It would help if you had beeswax and used extra virgin olive oil; it is straightforward and inexpensive; melt the wax in a water bath and add the oil to the melted wax, and beating it. Depending on the consistency we want, we have to add more or less oil. Once the mixture is made, it is put in the refrigerator.
