It is generally considered safe to store diesel in a gas can, even if it previously contained gasoline. While there are colour-coded standards for fuel containers, with red typically used for gasoline and yellow for diesel, the material of the cans is usually the same. As long as the container is empty before adding diesel, any trace amounts of gasoline left in the container will not be a problem and will not harm a diesel engine. However, it is best to use containers that are properly marked to avoid confusion and potential mistakes.

It is safe to put diesel in a gas can, but it is best to use properly marked containers
It is generally considered safe to put diesel in a gas can, but it is best to use a container that is properly marked for the fuel type. While the material of the cans—typically HDPE—may be the same for both diesel and gasoline, proper labelling reduces the risk of accidentally putting the wrong fuel in your vehicle.
Some gas cans may have vents, which can be hazardous if they cause fuel to spill. It is also important to note that diesel pumps have larger nozzles than gasoline pumps, so a gas can may not fit. In this case, it may be necessary to use your hand as a gasket, but this is not recommended.
If you are using a container that previously held gasoline, it is important to empty it before filling it with diesel. This will ensure that the gasoline does not dilute the diesel, which can reduce lubricity and engine performance. However, trace amounts of gasoline in the diesel will not be a significant issue.
While it is possible to store diesel and gasoline in the same transfer tanks and gas cans, it is important to pay attention to detail and avoid mixing up the fuels. Marking containers with "DIESEL" in block letters can help prevent mistakes.
Overall, while it is safe to put diesel in a gas can, it is best to use properly marked containers to reduce the risk of accidents and engine issues.

A small amount of leftover petrol in a diesel can won't hurt the injection pump
While it is not advisable to put diesel in a gas can, doing so will not damage the injection pump, provided that the can is emptied of petrol first. In fact, it is quite safe to store diesel in a gas can, and not uncommon, as the material of both cans is usually the same—HDPE. However, it is best practice to use containers that are marked properly for the fuel to be stored in them.
Diesel pumps have a larger diameter fill spout than gasoline pumps, and the tanks for gas and diesel are also typically different. The nozzle for the pump may not fit into the fill hole of a gas can, and using your hand as a gasket is not recommended. Therefore, it is better to have a yellow can for diesel and a red can for gas.
It is important to differentiate between diesel and gas cans to avoid accidentally putting diesel in a gasoline-powered vehicle, which can have severe consequences on the vehicle's health and operation. Diesel pumps are generally labelled in vibrant green and have larger nozzles to prevent them from being inserted into a gas tank. Diesel also smells different from gasoline, so staying vigilant can help prevent fuel mix-ups.
On the other hand, putting gasoline into a diesel tank can be even worse. Due to gasoline's high combustion tendencies, it would ignite much sooner than diesel fuel, causing potential catastrophic damage to the diesel engine and its components.

Diesel cans are half the price of red ones, but it's common to use red cans for diesel
It is a common misconception that diesel and gasoline containers are different and that they should not be interchanged. This is understandable, given that diesel cans are typically yellow and gasoline cans are typically red, and the fill openings for diesel pumps are larger in diameter than those for gasoline. However, it is perfectly safe to use a red gasoline can to store diesel. In fact, diesel cans are half the price of red ones, and it is common to use red cans for diesel.
The key thing to remember is that if a container can hold gasoline, it can hold most other fuels. The reverse is not always true, but a small amount of leftover gasoline in a diesel container will not cause any issues. This is because diesel and gasoline are both hydrocarbons that mix easily and dilute. As long as the container is emptied of gasoline before filling it with diesel, the tiny amount of leftover gasoline will not harm the injection pump. In fact, it is common practice to add gasoline to diesel in extreme cold to prevent jelling.
That being said, it is best to use containers that are properly marked for the fuel they contain. This is to prevent accidentally filling a diesel car with gasoline, or vice versa. One way to do this is to mark the containers with block letters indicating the fuel type. Another option is to use different types of containers for diesel and gasoline, even if the containers are not marked for a specific fuel type. This helps to ensure that the correct fuel is used and prevents accidents or damage to engines.
While it is possible to use a red gasoline can to store diesel, it is important to consider the risks associated with fuel storage. Fuel containers should be properly labelled and stored in a safe location to prevent spills or accidents. Additionally, it is important to follow local regulations and guidelines for fuel storage and disposal to ensure safety and compliance.
Overall, while it may be common to use red gasoline cans for diesel, it is important to prioritize safety and proper fuel storage practices. This includes using properly marked containers, storing fuels in a safe location, and following local regulations. By taking these precautions, individuals can help ensure the safe and effective use of diesel and gasoline.

The fill openings of diesel and gas cans are different sizes
While it is possible to put diesel in a gas can, it is not recommended. One of the main differences between diesel and gas cans is the size of their fill openings. Diesel pumps have a larger diameter fill spout than those used for gasoline. This means that the nozzle for the pump may not fit into the fill hole of a gas can, as some users have experienced.
The colour of the fuel can is also important. Typically, yellow cans are used for diesel, and red cans are used for gasoline. This colour-coding system helps users easily identify the type of fuel being stored and prevents mistakes when handling flammable liquids. Using the correct container for the correct fuel is considered best practice.
In addition, it is worth noting that diesel and gasoline have different vapour-pressure specifications. Gas cans should not have permanent vents because this can lead to hazardous situations if the vapours escape. Instead, properly-labelled gas cans are designed to contain the pressure.
While it may be possible to put diesel in a gas can, it is not advisable due to the differences in fill openings and the potential safety risks associated with mixing fuels. It is always best to use the correct container for the correct fuel type.

It is not advisable to keep diesel cans inside a car due to the risk of overheating
While it is possible to put diesel fuel in a gas can, it is not recommended. The gas will wipe out the lubrication qualities of the diesel and ruin the injection pump. Additionally, diesel pumps have a larger diameter fill spout than gasoline pumps, so the nozzle may not fit into the fill hole of a gas can, as some users have experienced.
It is also not advisable to keep diesel cans inside a car due to the risk of overheating. While some higher-quality cans, such as Wedco and Scepter, can be safely placed inside a vehicle without leaking or smelling, most people advise against it. To avoid the problem of fuel smell in your car, you can use a secondary plastic bin to hold the fuel container, so that any drips won't get on the interior of your car. If fuel does get on the interior, it can be removed with steam cleaning.
If you are looking to purchase a diesel can, it is recommended to get an approved container, such as one approved by your jurisdiction's department of transportation. Containers made of HDPE with capacities of 15-40 liters and attached spouts are also available. It is important to consider the weight of the container when choosing a size, as containers over 20 liters (about 5 gallons) may be too heavy for some people to lift into or out of a vehicle.
When filling a diesel can, it is important to use the correct type of fuel and to properly label the container. It is also recommended to empty any leftover petrol from the can before filling it with diesel to avoid contamination. In extreme cold, it is accepted to add petrol to diesel to prevent jelling.
