The waste oil we distil in the refinery is a complex product. The used lubricating oils are made up of partially deteriorated oil molecules. Hydrocarbon chains that are worn following many hours of use, contribute to a content of light oils in the waste oil.
Moreover, the waste oil also contains remains of petroleum and diesel fuel. These lighter oil products are distilled at a lower temperature than the base oil and are produced as by-products from the purification of the base oil.
Distillate F10: Around 15 % of the waste oil is distilled into a diesel fuel-like product. The product is sold only to heavy industry as heating fuel oil. The product is called Distillate F10 and you can read the product's data sheet here

DOG fuel LE: This waste oil contains around 2 % very light oils. The oil is similar to petroleum, and originates partly from actual petroleum residues and partly from worn short oil molecules. When the long oil molecules lubricate, some of them are worn and broken into shorter chains, similar to petroleum.
DOG fuel EX: From extraction of base oil originates a product consisting of base oil distillate with a concentrated content of aromatic compounds (PAH). DOG fuel EX is sold as heating fuel oil to heavy industry. You can read the product data sheet here:

DOG fuel H: DOG fuel H is the fuel oil that is produced from recycling oil emulsions and fuel oils. You can read the product data sheet here:
