Characteristics of Crude Oil The hydrocarbons in crude oil can generally be divided into four categories: Paraffins: These can make up 15 to 60% of crude. Physical properties: Heavy Fuel Oil is viscous and sticky consistency, making it much harder than crude oil to pump or collect during a spill, often fowling habitats for years.
