2. Lubricant - Wikipedia

   en.wikipedia.org/wiki/Lubricant

   Motor oil, a common lubricant. A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.

3. Motor oil - Wikipedia

   A significant factor in their gain in popularity was the ability of synthetic-based lubricants to remain fluid in very low temperatures, such as those encountered on Germany's eastern front, which caused petroleum-based lubricants to solidify owing to their higher wax content. The use of synthetic lubricants widened through the 1950s and 1960s ...

4. Grease (lubricant) - Wikipedia

   en.wikipedia.org/wiki/Grease_(lubricant)

   A true grease consists of an oil or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid or semisolid. [1] Greases are usually shear-thinning or pseudo-plastic fluids, which means that the viscosity of the fluid is reduced under shear stress.

5. Synthetic oil - Wikipedia

   en.wikipedia.org/wiki/Synthetic_oil

   Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil , but can also be synthesized from other raw materials.

6. Base oil - Wikipedia

   en.wikipedia.org/wiki/Base_oil

   The most common one is a type of paraffinic crude oil, although there are also naphthenic crude oils that create products with better solubility and very good properties at low temperatures. By using hydrogenation technology, in which sulfur and aromatics are removed using hydrogen under high pressure, extremely pure base oils can be obtained ...

7. Mineral oil - Wikipedia

   en.wikipedia.org/wiki/Mineral_oil

   Lubricants used for older refrigerator and air conditioning compressors are based on mineral oil, especially those using R-22 refrigerant. Mineral oil is used as a lubricant, a cutting fluid, and as a conditioning oil for jute fibres selected for textile production, a process known as 'jute batching'. [23]
