EN 590 ULSD Specifications
Diesel (DERV) is an essential fuel to power industrial sites, vehicle fleets, generators and more. DERV comes in a variety of grades and specifications which means that’s important you secure high-quality diesel that’s suitable for a range of applications. To learn more about diesel and it’s use cases you can find more information in our diesel FAQ.
Our ULSD is suitable for all road and off-road applications powered by diesel and you can view the specifications in the table below.

EN 590 Gas Oil Specifications
EN 590 gas oil is a dyed product that is often referred to as red diesel, marked diesel, 35-second oil or tractor diesel. You can learn more about gas oil in our guide to Gas Oil.
Gas oil is rebated-fuel that’s no longer available to may sectors and you can see if your business may access the fuel by using our red diesel FAQ.
Our gas oil meets BS 2869 (2010) Class A2 and EN 590 standards with 10 ppm (parts per million) sulphur content. It has a higher cetane number than A2 Class Gas Oil (another 10ppm sulphur content class of red diesel). You can view all our gas oil’s physical and chemical properties in the table below.

EN 590 Fame-Free Gas Oil
We also supply FAME-free gas oil to companies who require fuel with no biodiesel content. Fuel containing bio (FAME) has a tendency to absorb moisture and is therefore more susceptible to microbial attack which can cause issues such as clogged filters.
The specifications are the same EN590 and Class A2 but state a FAME content of <0.1%.
