In addition to industrial applications, lubricants are used for many other purposes. Other uses include cooking ( oils and fats in use in frying pans and baking to prevent food sticking), to reduce rusting and friction in machinery , through the use of motor oil and grease , bioapplications on humans (e.g., lubricants for artificial joints ...
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
K-Y Jelly was initially used as a surgical lubricant before it gained popularity as a personal lubricant. [citation needed] Lignocaine gel containing the local anaesthetic lignocaine is a prime example of a non-irritating substances used as surgical lubricant [citation needed] Medicinal castor oil was the original vegetable-based surgical ...
Due to the strong coupling between lubricant hydrodynamic action and the elastic deformation in contacting solids, this regime of lubrication is an example of Fluid-structure interaction. [4] The classical elastohydrodynamic theory considers Reynolds equation and the elastic deflection equation to solve for the pressure and deformation in this ...
A sample of synthetic motor 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.
Fat serves many purposes within an animal's body. Some of these uses include insulating the body to regulate internal body temperature, serving as an energy reserve, and cushioning the feet. [ 5 ] Many mammalian animals that live in cold regions of the globe, including both aquatic and terrestrial ecosystems, have developed a thick layer of fat ...

Oil additives are chemical compounds that improve the lubricant performance of base oil (or oil "base stock"). The manufacturer of many oils can use the same base stock for each formulation and can choose different additives for each use. Additives comprise up to 5% by weight of some oils. [1]
