| has gloss | eng: Heavy crude oil or extra heavy crude oil is any type of crude oil which does not flow easily. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°, meaning that its specific gravity is greater than 0.933. This mostly results from crude oil getting degraded by being exposed to bacteria, water or air resulting in the loss of its lighter fractions while leaving behind its heavier fractions. |

| has gloss | spa: Crudo pesado o crudo extra pesado es cualquier tipo de petróleo crudo que no fluye con facilidad. Se le denomina "pesado" debido a que su densidad o peso específico es superior a la del petróleo crudo ligero. Crudo pesado se ha definido como cualquier licuado de petróleo con un índice API inferior a 20 °, lo que significa que su densidad es superior a 0.933. Este resultado del petróleo crudo pesado es una degradación por estar expuesto a las bacterias, el agua o el aire, como consecuencia, la pérdida de sus fracciones más ligeras, dejando atrás sus fracciones más pesadas. |

| has gloss | zho: 重油是原油提取汽油、柴油后的剩余重质油，其特点是分子量大、黏度高。重油的比重一般在0.82～0.95，比熱在10,000～11,000kcal/kg左右。其成分主要是碳氫化合物，另外含有部分的（約0.1～4％）的硫黃及微量的無機化合物。主要用于大型蒸汽轮机锅炉的燃油，不过由于现在大功率燃气轮机的出现，以及重油燃烧对环境的污染，现在重油锅炉几乎被淘汰了。现在对重油的研究方向主要是长链烃的裂化，目的是通过裂解重油得到轻质的柴油或者煤油。此外，二戰其間重油可用於制造燃燒彈。 |
