How to Dispose of Old Diesel Fuel Safely

Are you planning to dispose of diesel fuel? If so, you should follow a few steps. If this is a one-off, you can discharge the fuel in your septic tank.

As diesel fuel can contaminate the environment, it is advised you seek tips when disposing of it.

If you are concerned about safely disposing of old diesel fuel, contact your local station and ask them for disposal instructions.

How to Dispose of Old Diesel Fuel Safely

Because diesel gasoline is a combustible and toxic substance, it must be disposed of properly.

It should never be flushed down the sewer or consumed.

This may damage your pipelines, contaminate ground and water, and even put your waste collectors at the risk of health problems.

Dumping diesel gasoline into a river, lake, pond or even a storm sewer is a violation of federal law.

It’s also against the rules to simply pour the diesel fuel into a container and leave it out in the open, which can create a great risk of fire or explosion.

So, whether you’re attempting to get rid of an old car with diesel fuel remaining in the tank or you’re about to discard some fuel, be sure to follow all the safety guidelines.

Know What You Have

This is only conceivable if you’ve always had control of the vehicle.

People started using diesel fuel during the 1920s and were cautious about dispose it. But as the years progressed, people became accustomed to using the fuel.

The fuel was easy to transport.

Treat diesel gasoline as a hazardous substance and dispose of it according to the instructions that will be provided by your waste management.

Basically, you have to get this form from the shipping company or the fuel retailer. If it is home-delivery, take the paperwork and ask your delivery provider if they will accept the package.

If it is an office delivery, take the papers to your boss or the manager or the person who is in charge of waste management so that they will know what to do with it.

Try to Use the Diesel Fuel

Attempt to utilize the diesel in a non-road vehicle, such as a boat or an airplane, would be very dangerous and risky. Diesel fuel is easier to ignite than gasoline, so you have to be extremely careful when using it.

Siphon the fuel from the tank or transfer it carefully into the container provided. Take care to cover the surface of the container with newspapers to prevent the fuel from leaking out.

Sell the Fuel

Inquire with anyone in your immediate vicinity who has a garage or driveway space that might be suitable for a storage tank. Keep in mind that not all fuel systems are compatible with every vehicle.

Many folks would gladly accept free gasoline in exchange for their time and effort in coming to meet you. It’s also possible to resell it for a little profit.

You may possibly sell gasoline to an old or abandoned property that is empty. Be as persistent and passionate as possible when trying to sell. The key here is to be sure that no one gets injured or hurt. The main goal is to responsibly dispose of the fuel in a safe manner.

Get in touch with hazardous waste haulers

Contact hazardous waste collectors or municipal recycling centers. They may require that you wear a respirator and safety glasses or gloves, and they will also ask if you’re developmentally disabled and in need of extra support.

In the past six years, the reuse or recycling of hazardous materials, including old diesel fuel, has become commonplace in industry.

Almost all local garbage firms offer hazardous waste collection programs, or they may know one that is available.

All firms are required to properly dispose of hazardous waste by law and by bettering the health and safety of their employees and customers.

How to Recondition Old Diesel Fuel

There are a lot of places to purchase diesel fuel additives, of course. You need to use a fuel additive that is specially formulated to condition old diesel fuel.

This surplus fuel is stored at a depot owned by the company.

Whenever possible, however, the executives will try to contact a previous customer who will be using the fuel again. If they are unable to contact the customer, they will liquidate the fuel.

Waste Management officials will pay top-dollar for old fuel, so they’ll tend to pay the vendor more than usual.

It goes stale and must either be replaced with fresh stock or reconditioned. The reconditioned fuel goes through the distillation process, and after it passes the distillation process, it has less impurities.

You might profit from the process by injecting it into your own diesel engine.

You will be able to save a buttload of fuel after reconditioning your old fuel.

Instead of disposing of old diesel fuel, recondition it.

Dilute the diesel fuel by adding some water to it. Once you’ve added enough water, make sure to ventilate the area.

Let the water evaporate so the diesel fuel does not pose a health hazard. Using a funnel, spoon, and/or some pliers, pour the diesel fuel into a plastic container.

When you’re ready to use the diesel, drain it from the container.

Transfer Diesel Fuel into Drums

Fill a gallon drum with 75% diesel fuel until it is 55% full.

Be sure the drum is clean and free of rust. If you’re using an old drum that contained gasoline, rinse it first.

Once you’re finished, run a piece of a pipe over the drum. This will serve as a vent so the remaining fuel in the barrel vaporizes faster.

Working with more than 50 gallons of fuel is dangerous and very risky.

Use a drill to make several holes in the drum’s base, and equip a drill with a nozzle and a screw on tip. Plug the nozzle into the drill.

Then, screw the screw on tip onto the nozzle. Thread the nozzle through the holes in the drum’s base.

Then, screw the drill into the hole in the handle. Drill until you reach the hole in the handle.

Attach the hose to the fuel filler of the combustion engine, and use an absorbent to catch the fuel as it drips into the drum.

Before you begin, make sure clamp a gasket on the 55-gallon drum.

This can be done by rotating the drum around until you think the gasket is in place. Fill the drum halfway with diesel fuel from a 55-gallon tub or drum.

This should only be done after you have clamped the gasket in place. Do not screw or tighten the drum into place yet.

Add Ether Or PRD-D

Using a graduated cylinder helps prevent spillage of the additive. Adding spring clips to the cylinder will make it easier to pour the additive.

PRD-D or 280 oz. is all you need to add a 3 percent salt content to the 50-gallon drum of fuel.

PRD-D and ether are diesel additives that should be used with older engines.

They reduce fuel usage and operating costs.

Add Fuel Re-Conditioner to the Stored Fuel Storage

You don’t need a gallon drum if you already know how much diesel fuel you have in your container. With PRD-D, the chemistry is not changed because the PRD-D is fuel.

To the old diesel fuel, add the PRD-D and the oil (if you are using oil to re-condition).

As the mixture sits, it will slowly start to break down and create new fuel. After the mixture sits for at least two or three days, be sure to test the fuel to make sure it is ready to go.

Per gallon of old fuel, the PRD-D to 2.4-inch wide strips should be stirred for 5 minutes.

The contents of the container should be thoroughly mixed to ensure that the ether has penetrated all the old diesel fuel. This mixture is then placed in the storage tank.

The storage tank should be filled with at least a gallon of new diesel fuel.

The storage tank should be isolated from the air, and the storage tank should be kept either in a freezer or in the refrigerator for 24 hours.

PRD-D or 5 .6 ounces of ether is added to diesel fuel in a way to make diesel fuel run as if it were new.

If you don’t have the ratio of PRD-D to old diesel fuel on hand, you may need to improvise while using PRD-D or ether.

Allow the Diesel Fuel to Sit Before Use

Allow a day or longer for the old fuel to settle before you begin to use once again.

This will verify that it has been properly filtered and that all of the water has drained out of the fuel.

Follow the same rules for cleaning the carburetor and fuel injector jets, making sure to neutralize the acid that may have been introduced into the fuel.

Then use the gasoline as fuel in the vehicle. Once fueling is complete, leave the vehicle alone for a full day.

Because of the many legal and health ramifications, it may be difficult to properly dispose of used diesel fuel.

When dealing with hazardous garbage, considerable caution is to be taken with handling hazardous materials.

For example, diesel fuel is not easily flammable and can pose a serious danger to one’s health. If diesel fuel is spilled, it must be cleaned up immediately.

However, if diesel fuel is allowed to build up, it could pose harm to the soil and water systems.

If you’re not sure how to dispose of used diesel fuel, just ask the hazardous waste collection center staff.

Instead, call a hazardous waste collection agency in the location where the diesel was dumped and have them pick it up.
