No, gazole diesel is not the same as regular diesel fuel. Gazole diesel is a type of diesel fuel commonly used in Europe, while regular diesel fuel is the standard type of diesel used in the United States. They may have slightly different chemical compositions and properties.
Diesel fuel can appear different colors due to variations in its composition and any added dyes. Typically, diesel fuel is a light yellow or pale green color. However, impurities, contaminants, or oxidation can darken its color. Additionally, some countries regulate the color of diesel fuel for tax or identification purposes, leading to variations in color.
Where is the diesel fuel filtered

If the van has a diesel engine, then you MUST use diesel fuel. Unleaded gasoline will destroy a diesel engine. Diesel fuel is also used as a lubricant in a diesel engine. The use of any other fuel except diesel will result in serious damage. If you have put unleaded in your diesel, do not start or drive this vehicle until you drain the tank and change all the fuel filters.If the van has a diesel engine, then you MUST use diesel fuel.
