How to Dispose of Gasoline [6 Best Ways]

Gasoline is a versatile, widely used substance that allows us to run our civilization. Gasoline, like other hydrocarbons, can form unhealthy substances in the environment when not properly disposed of.

When gasoline remains unused for an extended period in your garage or while riding a lawnmower over the winter, it can degrade or get contaminated.

If you have gasoline that you need to get rid of, it’s important to take the necessary precautions to do so safely. In this blog post, we will discuss how to dispose of gasoline properly so that you can stay safe and avoid any potential accidents.

There are a few different steps that you can use to dispose of gasoline, depending on how much you have and what resources are available to you.

1. Inspect whether the gasoline is old or contaminated

Pour some gas into a glass jar and check whether it’s old or tainted. Pour some new gasoline into another container for comparison. If the questionable gas is darker or has a “sour” odor, it has likely aged to the point of losing efficacy. Today’s gasoline is more shelf-stable than previous fuels due to ethanol, a preservative.

2. Use up old gasoline

Although old gas has lost some of its power to fire an engine on its own, it’s typically safe to use up by diluting it with new gas in the tank of an outdoor power tool or car. Follow the correct ratios, and the old gas will reduce a full gas tank’s combustion ability by so little that it’s no longer a problem.

Adding old gas to fresh gas in a vehicle might be done at home, but you may also inquire about using fuel additives at your local auto parts store to increase the ratio of old to new gas in your tank so that you can use the supply up faster.

Injector cleaners are frequently beneficial in utilizing old petrol, depending on the engine and fuel you’re using, which experts can evaluate.

3. Research the nearest disposal center for old or contaminated gasoline

If you have a small amount of old or bad gasoline, your best option is to take it to a hazardous waste disposal center. The process is free, and it will ensure that the gas is properly handled.

Call ahead to find out the hours and days that the facility is open and what type of containers they require you to use. Once you arrive at the center, an attendant will likely take the gas from you so that you don’t have to deal with it yourself. 

Larger quantities of old or contaminated gasoline may need to be taken care of by a professional company specializing in hazardous waste removal. This might be necessary if you have hundreds of gallons or more of unusable gas.

If this applies to you, call a few different companies to get quotes and find the best option.

4. Transfer gasoline to a government-certified container

Use a funnel to carefully move the old or contaminated gasoline from its current container into one government-certified specifically for gasoline, such as a jerry can or plastic gas jug. Many fire regulations state that each container should contain no more than five gallons of fuel.

5. Deal with any gasoline spills

If any stains have developed on your clothing, change them and deal with the dirty set. To remove the extra, use a white towel to blot it away.

Cover the afflicted region with baking soda to soak up what your cloth cannot; leave it for a few minutes, then brush it clean. Finally, rub liquid dish soap into the discoloration to treat it before washing the clothing by itself in the hottest water its fibers can withstand.

To ensure gasoline is completely removed, only dry until it’s clear that no more traces of gas exist. Otherwise, residual gas might cause combustion in the dryer when it comes into contact with heat.

6. Transport gasoline to the disposal center

Never, ever smoke in the car while transporting gas. Fumes might still be present, and you could have been splashed with gas, which takes a few gallons to become combustible when exposed to open flames in a confined place.

You should be able to empty your gasoline into their storage vessel and take the empty container home for future recycling needs once you arrive at the disposal facility.
