EN 590 Diesel Fuel Specifications (ULSD)

All road diesel must meet EN 590 specification and many off-road engines in Europe are designed with ULSD EN 590-standard fuel in mind. Find out what this specification means.

Read the Specifications for EN 590 Diesel and EN 590 Gas Oil

EN 590 is the current standard for all automotive diesel fuel sold in the European Union member states and other European countries. This grade of fuel is also called ultra-low sulphur diesel (ULSD).

All road diesel (DERV) that is now sold in the UK meets the EN 590 standards and has a compulsory 7% by volume biodiesel component blended into it, usually EN 14214 FAME biodiesel. This is optional for EN 590 fuel used as gas oil, as is the cetane content.

EN 590 compliant fuels supplied by Crown Oil include red diesel (EN 590 gas oil )and DERV diesel (EN 590 diesel).

Crown Oil also supplies fuels that meet Class A2 or Class D gas oil, providing the highest quality fuel for each specific application.

EN 590 Gas Oil Specifications: what physical properties does EN 590 diesel have? What are the fuel’s chemical properties?

Gas Oil meets BS 2869 (2010) Class A2 and the EN590 specification. Gas oil is a dyed and marked product, to be used for small furnace or boiler applications, stationary diesel and untaxed engines. Crown Oil supplies red diesel that meets EN 590 standards.

For diesel fuel to meet EN 590 specifications, it means that the fuel must have the required physical and chemical properties that the standard requires. The table below shows the physical properties and chemical properties that the EN 590 standard requires, as well as how the fuel meets these characteristics.
