The colour of diesel fuel varies depending on its intended use. For ordinary civilian vehicles, diesel fuel is typically clear and colourless. However, diesel fuel intended for use in heavy-duty machinery, generators, or off-road vehicles like tractors and bulldozers is known as dyed diesel and comes in red or blue. Additionally, the colour of the diesel pump handle at gas stations is often green, but this can vary, and it is important to read the labels to ensure the correct type of fuel is selected.

What You'll Learn
Diesel fuel pumps are green at most gas stations
Although there is no industry standard, diesel fuel pumps are typically green at most gas stations. In fact, the unofficial colour for diesel fuel at 99% of gas stations across America is green. This colour coding is useful for consumers, as it helps them identify the right pump for their vehicle. However, it is important to note that the colour of the pump does not always indicate the type of fuel. For example, at BP stations, green is the brand colour and is used for their gasoline handles, which can be confusing for consumers who are used to green pumps for diesel.
In Europe, the colour system is different, and there have been reports of consumers mistakenly pumping gas into their diesel vehicles at European-owned American gas stations due to the colour coding. To avoid this issue, some consumers choose to avoid BP stations altogether. While the colour of the pump can be a helpful indicator, it is always important to read the labels and confirm that you are selecting the correct type of fuel.
In addition to the colour of the pump, the handle size and shape of diesel fuel pumps may also differ from those of gasoline pumps. Diesel nozzles are typically larger and may not fit into a gas vehicle. Some gas stations also have special high-flow diesel pumps that are offset from the regular gas lanes. These pumps are designed to accommodate the larger tanks of trucks and other diesel-powered vehicles.
It is worth noting that the colour of the diesel fuel itself is typically clear and colourless, rather than green. This standard diesel fuel is intended for use in ordinary on-road vehicles such as pickup trucks, SUVs, and big rig trucks. However, there are also dyed diesel fuels used for specific purposes, such as red diesel for off-road vehicles and blue diesel for government and military use. These dyed diesel fuels are heavily regulated and not available to the general public.

At BP stations, diesel pumps are not green
While green is the unofficial colour for diesel fuel at most gas stations across America, at BP stations, diesel pumps are not green. Instead, the diesel pumps at BP are black, while the gasoline handles are green. This has caused confusion for some customers, who have accidentally put gasoline in their diesel vehicles, causing extensive damage to their fuel systems.
The colour green is typically associated with diesel fuel, and this is consistent across many gas stations. However, there is no standardised fuel pump colour protocol, and gas stations can use whatever colours they like for their fuel pumps. This means that at BP stations, the diesel pumps do not have to be green and can be a different colour, such as black.
Some customers have expressed frustration with BP's colour scheme, arguing that it has led to mistakes and costly repairs. They believe that the diesel pump should be green to match the colour of diesel fuel caps and the standard colour for diesel at most other gas stations. However, others have argued that there are measures in place to prevent incorrect fuelling, such as having to select the correct grade and the size difference between diesel and gasoline nozzles.
Despite the controversy, BP has not changed its pump colour scheme. This has led some customers to avoid BP stations altogether, opting for other gas stations where the diesel pumps are green. This highlights the importance of customer experience and the potential impact of seemingly small design choices.
While the colour of fuel pumps may vary, it is always essential to read the labels and confirm the correct fuel type before filling up. This can help prevent mistakes and reduce the risk of damage to vehicles. Being vigilant and taking the time to double-check can save customers from costly repairs and provide peace of mind.

Diesel fuel is clear and colourless
While the colour of the pump handle for diesel fuel is often green, the diesel fuel itself is clear and colourless. This is the standard diesel fuel used by civilians on the road in ordinary on-road vehicles like pickup trucks, SUVs, and big-rig trucks.
The clear diesel you get at a gas station is properly formulated for travelling purposes and is subject to regular fuel taxes, which help pay for things like highway maintenance. It is also thicker and easier to refine, making it more efficient. However, it should only be used in diesel engines, as putting diesel fuel in a car made for regular unleaded gas can cause serious problems.
There are some exceptions to the colour of diesel fuel. For example, professional workers and government employees use a type of diesel known as "dyed diesel", which comes in red and blue. These fuels are functionally similar to the colourless kind, but their usage is heavily regulated. Red diesel fuel is intended for heavy-duty machinery, generators, or off-road vehicles like tractors and bulldozers, while blue diesel is only permitted for use in official government vehicles, such as military equipment.
It is important to note that while the colour of the pump handle can be a helpful indicator, it is not a guarantee. The colours may vary between gas stations, and in some cases, such as at BP stations, the colour for diesel may be different. Therefore, it is always essential to read the labels and confirm that you are selecting the correct fuel type before pumping.

Some diesel fuel is dyed red or blue for special use cases
In the United States, diesel fuel used for on-road vehicles is typically clear and comes at a higher price due to taxes and regulations. However, some diesel fuel is dyed red or blue for special use cases.
Red diesel, also known as off-road diesel, is used for off-road vehicles and equipment in industries such as agriculture, construction, and mining. It is tax-exempt, making it a cost-effective choice for non-road applications. The red dye makes it easy to identify and enforce its legal use, and using red diesel on public roads is illegal and can result in hefty fines or even jail time. In the United Kingdom, red diesel is commonly used in registered agricultural or construction vehicles, and authorities regularly conduct roadside checks to ensure compliance.
Blue diesel is another type of dyed diesel that is specifically used for government vehicles and is not generally available to the public. It serves as a specialized form of dyed fuel, indicating its exclusive use by government entities.
The use of dyed diesel fuel is highly regulated to prevent misuse and ensure proper taxation. These regulations help maintain the distinction between regular diesel fuel for on-road vehicles and dyed diesel fuel for off-road machinery and specialized purposes.

Pumping diesel fuel is an experience of sounds, not sights
The colour of a diesel fuel pump handle can vary, but it is often green. Some people associate green with diesel and expect diesel fuel to be pumped from a green-handled pump. However, it's important to read the labels and buttons on the pump, as the colour alone is not a guarantee.
The sound of a diesel fuel pump can also indicate its condition. A failing fuel pump may make a loud, whining noise as it works harder to pump fuel, indicating that it's beginning to fail. Other signs of a failing fuel pump include a loss of power or performance, difficulty starting the vehicle, and stalling or hesitation while driving.
The sound of the fuel pump can also vary depending on its brand and age. For example, some pumps may be quieter and less noticeable, while others may be louder and noisier. Additionally, fuel system cleaners may contribute to the sound of the fuel pump, as their use or discontinuation can impact the pump's volume.
The experience of pumping diesel fuel is thus characterised by the sounds of the pump, the vehicle, and the interaction between the two. While the colour of the pump handle may initially guide the user, the auditory cues become the primary focus during the pumping process, making it an experience of sounds rather than sights.
