Definition

1. Noun:
   • A fuel oil: "gas oil" is a liquid petroleum product obtained by distilling crude oil. It has a boiling point and viscosity that falls between lighter fuels (like gasoline) and heavier residues. It is primarily used as fuel for diesel engines and for heating.

Usage Examples

• Noun:
  • The factory uses gas oil to power its generators.
  • Heating systems in some older buildings still run on gas oil.

Advanced Usage

• Industrial Context: In refining and industrial terminology, "gas oil" specifically refers to the distillate fraction that is further processed to produce diesel fuel and heating oil.
  • The refinery's atmospheric distillation unit separates crude into naphtha, kerosene, and gas oil.

Variants and Related Words

• Diesel fuel: A common, more specific end product derived from gas oil.
  • Modern diesel engines are designed to run on ultra-low sulfur diesel fuel, which is refined from gas oil.
• Heating oil: A domestic fuel oil very similar to diesel, often synonymous with gas oil in certain markets.
  • We need to order more heating oil for the winter; it's essentially the same as gas oil.

Synonyms

• Diesel oil
• Distillate fuel oil
• No. 2 fuel oil (A standard classification)
