Diesel

Diesel fuel in general is any liquid fuel used in diesel engines, whose fuel ignition takes place, without any spark, as a result of compression of the inlet air mixture and then injection of fuel. Sulphur occurs naturally in crude oil and the Sulphur content can range anywhere between 100 and 33,000 parts per million (ppm) If the Sulphur is not removed during the refining process it will contaminate the Diesel fuel. Depending on the crude oil used, as well as the refinery configuration, sulphur levels in Diesel fuel it can be as low as 10 ppm or higher than 10,000 ppm.

• Low Sulphur grade Diesel – 50 ppm Sulphur (max) Low-Sulphur Diesel 50 ppm

• Low Sulphur grade Diesel – 10 ppm Sulphur (max) Low-Sulphur Diesel 10 ppm
