Oil vs Grease
It is quite easy to understand why many people tend to interchange oil and grease. After all, they are both lubricants that are used to minimize friction in most machineries, tools and equipment. But actually, oil and grease are two distinct compounds that we use each day.
Physical Appearance
One of the things that differentiate oil from grease is how it looks like. In room temperature, oil is usually in liquid form. It only becomes solid when it is subjected to extremely cold temperatures for long periods of time. On the other hand, grease is a semisolid compound. That means compared to oils, grease is more able to keep its shape and does not follow the shape of the container.
Where They Come From
Another distinct difference between oil and grease lies in its derivation. Although both oil and grease are generally derived from animal fats, oils can also be derived from plant sources as well. In this case, oil is usually derived either from the seeds or the leaves of the plants. Grease, on the other hand, can also be created through the use of different minerals. Examples of these types of grease are those that are made out of silicon, fluoroether and Carboxymethyl cellulose which are blended with compounds such as tar, mica and graphite.
Where They are Used
Between the two, oil is more versatile and used in a variety of different ways. They could be used anywhere from lubricating your car engine to frying your food, styling your hair and even help relax and soothe your body. On the other hand, grease is usually used in machineries, tools and equipment which require minimal shifting of the lubrication to occur. They are also used to lubricate certain materials that would otherwise have a corrosive reaction when oil is used on them such as rubber, which is why grease is often used in many laboratories. And because of its high viscosity level, grease is also used to lubricate machine parts, tools and equipment that are subjected to high temperatures.
Summary:
1.Both oil and grease are generally used by people to lubricate machine parts, tools and equipments that are used every day.
2.Grease is made out of either animal fat or a combination of different minerals that are found in nature. Oil is extracted from animal fat or plant extracts.
3.Grease is semisolid in its appearance and not easily affected by extreme temperatures, which is why they are commonly used in tools, machines and equipments. Oil, in room temperature, is liquid and becomes solid when subjected to extremely low temperatures, and tends to evaporate when subjected to extremely high temperatures. Oil is used by people in cooking, personal grooming, lubrication and so much more.
