Two types of diesel fuel my employer might use are...  clear diesel and mixed diesel  clear diesel and dyed diesel  low sulfur diesel and high sulfur diesel

The two types of diesel fuel your employer might use are clear diesel and dyed diesel.

Clear diesel is a type of diesel fuel that is transparent and untinted. It is typically used for on-road vehicles and is subject to road taxes.

On the other hand, dyed diesel is a type of diesel fuel that has a red dye added to it. This type of diesel is typically used for off-road vehicles, such as farming equipment or construction machinery, and is not subject to road taxes.

Another type of diesel fuel that your employer might use is low sulfur diesel and high sulfur diesel.

Low sulfur diesel has a sulfur content of 500 parts per million (ppm) or less. It is used in most on-road and off-road vehicles.

High sulfur diesel has a sulfur content greater than 500 ppm and is typically used in older vehicles that do not have advanced emission control systems.

So, the types of diesel fuel your employer might use depend on the type of vehicles they have and their specific needs.
