Specifications for EN 15940 paraffinic diesel fuel
British Standard (BS) EN 15940 is a paraffinic diesel fuel specification that governs a new generation of cleaner transport fuel for use in road vehicles. Paraffinic diesel fuels are synthetically produced diesel fuels, such as the advanced renewable paraffinic diesel, Crown HVO fuel, which meets these specifications, as well as Shell GTL fuel.
Because Crown HVO and GTL meet these specifications, they are able to be used as a drop-in fuel in engines and machinery that have OEM approval, including Mercedes-Benz, Ford (for its Transit vans), Volvo, Peugeot, Citroen, Renault, John Deere, DAF, MAN, and more. In short, so long as there is OEM approval, EN 15940 fuels can be used as a drop-in replacement for fuels designed to run on EN 590 ULSD.
