What Is Number 1 Fuel Oil?

by Krystal

Number 1 fuel oil, also known as kerosene or clear kerosene, is a type of distillate fuel. It is commonly used in heating applications and as a feedstock for various chemical processes. This article aims to provide a thorough understanding of number 1 fuel oil, its characteristics, uses, and advantages.

What is Number 1 Fuel Oil?

Number 1 fuel oil is a refined petroleum product characterized by its lighter weight and lower viscosity compared to heavier fuel oils. The American Society for Testing and Materials (ASTM) classifies it as a distillate fuel, which means it is produced through the distillation process of crude oil. This process separates the different components of crude oil based on their boiling points, yielding various types of fuel oil.
