Gas Can For Diesel Fuel: Safe Or Not?

can a gas can hold diesel fuel

It is generally considered safe to use a gas can to hold diesel fuel, provided that it is not galvanized and that any residual gasoline is emptied before filling it with diesel. Gas cans typically have a smaller fill opening than diesel cans, so a diesel pump nozzle may not fit into the fill hole. It is also important to note that while trace amounts of gasoline in a diesel can may not be a problem, larger amounts of gasoline can lower the cetane rating of the diesel and ruin an expensive injection pump. It is always best to use containers that are properly marked for the type of fuel being stored and to follow federal and state laws and regulations regarding fuel transport and storage.

It's safe to use a gas can for diesel fuel, but ensure it's not galvanised

It is generally safe to use a gas can to hold diesel fuel, but there are some important precautions to take. Firstly, ensure that the gas can is not galvanised, as diesel can react with galvanised cans and ruin your injection pump. It is also important to make sure that the gas can is thoroughly cleaned before filling it with diesel fuel. While trace amounts of gasoline in the diesel fuel will not be a problem, it is best to minimise any potential issues by emptying and rinsing the can. This is because gas will wipe out the lubrication qualities of the diesel, which can cause issues with your injection pump.

It is recommended to use containers that are properly marked for the fuel they are storing. Diesel and gasoline are both hydrocarbons that mix easily, and they often move in the same pipelines, are stored in the same tanks, and are transported in the same tankers. As such, a small amount of gasoline mixed with diesel fuel will not be an issue. In fact, some older diesel car manuals recommend adding a little gasoline to diesel fuel in cold temperatures to prevent jelling.

However, it is always best to use the correct container for the fuel you are storing. Diesel pumps have a larger diameter fill spout than gasoline pumps, so the fill holes on diesel cans are typically larger than those on gas cans. This can make it difficult to fill a gas can with diesel fuel, as the nozzle may not fit into the fill hole. In addition, it is important to be aware of any local laws or regulations regarding fuel storage and transportation, as some places have strict requirements for fuel containers to be properly labelled and coloured.

Overall, while it is safe to use a gas can to hold diesel fuel in an emergency, it is best to use a dedicated diesel can if possible, to ensure that your equipment remains in good working order and to avoid any potential issues with fuel mixing or container labelling.

Clean the gas can thoroughly before refilling with diesel

When switching from storing gasoline to diesel fuel in a container, it is important to clean the gas can thoroughly before refilling it with diesel. This is to ensure that any residual gasoline does not contaminate the diesel fuel, which could potentially cause issues for your engine.

Firstly, ensure that the gas can is made of plastic and is not galvanized, as diesel can ruin the container and your injection pump. Next, empty the gas can of any remaining fuel. If there is only a small amount of gasoline left, it may not be necessary to clean the can at all, as a tiny amount of gasoline mixed with diesel will not be harmful. However, if there is more than a few drops of gasoline left, it is recommended to wash the can out with diesel fuel. Alternatively, you can use dish soap and water to clean the can, ensuring that you rinse it thoroughly afterward.

It is important to note that you should never clean a plastic gas can with compressed air, as static electricity could ignite the gas vapors, creating a dangerous situation. Additionally, always make sure the can is completely dry before refilling it with diesel fuel to avoid water contamination.

Some other methods for cleaning a gas can include using gravel or screws inside the container to help remove tough grime and dirt when shaking. You can also try filling the can with water and shaking it to dissolve any varnish or rust inside, although this may take a few weeks to fully eliminate the smell.

Avoid using compressed air to clean the gas can

A gas can can be used to hold diesel fuel. However, it is important to note that gas cans and diesel cans have different fill openings. Diesel pumps have a larger diameter fill spout, so it may not be possible to fill a gas can with diesel fuel without using your hand as a gasket, which is not recommended. It is best to use a dedicated diesel can to avoid any issues.

Now, when it comes to cleaning the gas can, it is important to avoid using compressed air. Here are several reasons why you should avoid using compressed air to clean a gas can:

Safety Hazards

Compressed air can be dangerous, even deadly when misused. It can exert extremely high forces that turn small particles into high-velocity projectiles. These objects can become shrapnel and cause severe damage or injury if they come into contact with someone. Even dust and dirt can cause skin abrasions when propelled at high speeds.

Environmental Impact

Compressed air cans contribute to greenhouse gas emissions. The propellants used, such as hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs), are potent contributors to climate change. According to the Environmental Protection Agency (EPA), HFCs are much more harmful than carbon dioxide as a greenhouse gas.

Damage to Electronics

Compressed air is often used to clean electronics, but it can actually cause more harm than good. The high-pressure air can force dust and debris deeper into the device, causing damage to sensitive components. It can also lead to condensation, resulting in short circuits and other issues.

Alternative Cleaning Methods

Instead of using compressed air, there are safer and more effective alternatives for cleaning. For example, a soft-bristled brush, a small vacuum cleaner, or a microfiber cloth can be used to gently remove dust and debris from electronics.

Regulatory Restrictions

In some places, there are laws and regulations that govern or restrict the use of compressed air for cleaning. For example, in Canada, cleaning with compressed air is not allowed by law, according to the Canadian Centre for Occupational Health and Safety (CCOHS). In the United States, the Occupational Safety and Health Administration (OSHA) regulates the use of compressed air for cleaning, allowing it only under specific conditions and with proper safety measures in place.

In conclusion, while a gas can can technically hold diesel fuel, it is recommended to use dedicated fuel cans to avoid any issues. Additionally, when cleaning the gas can, it is important to avoid using compressed air due to safety hazards, environmental impact, potential damage to electronics, alternative cleaning methods, and regulatory restrictions.

A small amount of leftover petrol won't harm your injection pump

It is generally advised to use separate containers for diesel and gasoline. This is because gasoline possesses zero lubricating qualities for diesel fuel pumps, which can lead to fuel injection system damage. However, if you have a small amount of petrol left in a container that you wish to use for diesel, there are a few things to consider.

Firstly, ensure that the container is not galvanised, as diesel will react with the galvanisation and ruin your injection pump. Secondly, while trace amounts of petrol left in a container that is then filled with diesel will likely not cause any issues, it is important to remember that fuel contamination is a top cause of diesel fuel injection pump failure. Therefore, it is always best to use a dedicated diesel can to avoid any potential issues. If you do choose to use a container with leftover petrol, it is crucial to empty the container of as much petrol as possible before filling it with diesel.

It is worth noting that diesel and gasoline are both hydrocarbons that mix easily and dilute, so even if a small amount of petrol is left in the container, it will likely not cause any harm to your injection pump. However, it is always better to be safe and take the proper precautions when dealing with fuel.

In addition, it is important to properly label your fuel cans to avoid confusion and potential hazards. While it may be tempting to use a gas can for diesel in a pinch, it is not recommended as the fill openings for diesel and gasoline are typically different, and you may end up with diesel all over your hand!

Diesel and gasoline often move in the same pipelines and tanks

The transportation of gasoline and diesel fuel is a complex process that involves various modes of transportation, including pipelines, tankers, trucks, railroads, and barges. While it is true that diesel and gasoline often move through the same pipelines and share storage tanks, it is important to understand the journey from crude oil to the final product at retail fueling stations.

Crude oil is transported from its source to petroleum refineries, where it undergoes refining, processing, and separation into different petroleum products. These products include gasoline, diesel fuel, kerosene, jet fuel, propane, industrial lubricants, and asphalt. The lighter products, such as gasoline, float near the tops of the towers, while heavier ones like diesel settle at the bottom, allowing for their separation based on density.

After the initial separation, gasoline and other petroleum products from different refineries are often transported through shared pipelines in batches. This process leads to some mixing or "commingling" of the products. To ensure the quality and specifications of the gasoline, it is tested as it leaves the pipelines. If it fails to meet the required standards, it is sent back to the refinery for additional processing.

From the pipelines, gasoline is typically sent to large storage terminals near consuming areas. At this stage, different companies that own service stations in the same area may purchase their gasoline from the same bulk storage and distribution terminal. The gasoline is then transported by tanker trucks to smaller blending terminals, where fuel ethanol may be added, and eventually to the retail fueling stations.

While diesel and gasoline may share pipelines and storage tanks during the early stages of the refining and transportation process, they are separated and processed into distinct products. The mixing that occurs during transportation is managed through dilution in large tanks, and the products are tested to ensure they meet the required specifications. Therefore, by the time these fuels reach the retail level, they have undergone rigorous refinement and quality control measures to produce the final products that consumers use.
