Today the world demands variety in every sphere, and oil has not been left far behind.
Oil finds its uses in our everyday life in various forms and thus as per the usage and need the variety of oil needed changes. Some primitive uses have been cooking, application, for oiling machinery etc.
What exactly is oil?
This is a rather difficult question to answer as oil in its crude sense is different from the oil we use for cooking purpose and further is very different from the oil we use for our external body applications. Thus, with every use arises a demand for a different type of oil.
Types of Oil
The most common classification of oil can be done in two categories by their source of origin:
(A) Mineral Oil
We all know crude oil which is the by-product of the petroleum industry and is widely used for its property to be converted to other forms of energy. The Mineral oil though is neither extracted from mineral nor does it provide us with any, it is just a misnomer.
Crude oil is further converted to:
- Liquefied Petroleum Gas
(B) Organic Oil
The environment around us is very productive and indeed very useful to us. Organic oils are those oil which we receive from plants, animals, and other organisms through metabolic processes. It contains Lipids (which is a single term used to denote the fatty acids and steroids present in the organic oil), proteins, waxes and other alkaloids.
The organic oils are the ones that we encounter in our daily life for various purposes. They are a part of our everyday routines like cooking, cleaning, cosmetic, painting, lubrication (at times), etc. It further comes in huge varieties.

The next classification can be done by the properties of the oil, i.e., its viscosity, toxicity or even the volatility. On this basis oil can be put in these categories:
• Very Light Oils
These oils are highly volatile with very less viscosity. Light oils are toxic. They include naphthalene, ether, spirit, etc.
• Light Oils
These oils are not as volatile as the previous classification. The every day fuels like domestic fuels, diesel, and marine gas oils fall under this category.
• Medium Oils
These oils are volatile but with a very slow rate of volatility. They are harmful to the fur animals and sea life.
