Low Sulphur Gas Oil is often called Gas Oil 10ppm or Gas10 as it has only 10 parts sulphur per million. It is specified for use in most modern engines including John Deere, Case New Holland, Argo and CAT engines. It is critical that you use Low Sulphur in these engines as High Sulphur Gas Oil (1000ppm) can damage filters and render warranties null and void.
High Sulphur Gas Oil (Gas Oil 1000ppm) was in older tractors and stationary machine including generators, heating and grain dryer systems.
Both Low Sulphur and High Sulphur Diesels are marked with a green dye in the same way as standard marked gas oil, meaning it is illegal to use as a fuel for on-road vehicles. As the products are dyed or marked, this leads to other names for the products including Marked Gas Oil, Marked Diesel, Agri Diesel or Green Diesel. The key difference is ensuring you know if you require Low Sulphur or High Sulphur Gas Oil.
