Colza oil is a non-drying oil obtained from the seeds of Brassica campestris, var. oleifera, a variety of the plant which produces Swedish turnips. Colza is extensively cultivated in France, Belgium, the Netherlands and Germany; and, especially in the first-named country, the expression of the oil is an important industry. In commerce, colza is classed with rape oil, to which both in source and properties it is very closely allied. It is a comparatively inodorous oil of a yellow color, having a specific gravity varying from 0.912 to 0.920. The cake left after expression of the oil is a valuable feeding substance for cattle. Colza oil is extensively used as a lubricant for machinery, and for burning in lamps. ...more on Wikipedia about "Colza oil"

Gear oil is a motor oil made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. It is of a higher viscosity to better protect the gears and usually is associated with a strong sulfur smell. The high viscosity ensures transfer of lubricant throughout the gear train. This is necessary since the devices needing this heavy oil do not have pumps for transferring the oil with only a portion of the lowermost gears bathed in an oil sump. This heavy oil can create viscous drag leading to inefficiencies in vehicle operation. Some modern automatic transaxles (integrated transmission and differential) do not use a heavy oil at all but lubricate with the lower viscosity hydraulic fluid, which is available at pressure within the automatic transmission. ...more on Wikipedia about "Gear oil"
Graphite (named by Abraham Gottlob Werner in 1789, from the Greek γραφειν: "to draw/write", for its use in pencils) is one of the allotropes of carbon. Unlike diamond, graphite is a conductor, and can be used, for instance, as the material in the electrodes of an electrical arc lamp. Graphite holds the distinction of being the most stable form of solid carbon ever discovered. ...more on Wikipedia about "Graphite"
Grease is a lubricant of higher initial viscosity than oil, consisting originally of a calcium, sodium or lithium soap jelly emulsified with mineral oil. ...more on Wikipedia about "Grease (lubricant)"
Krytox is a trademark of a family of high performance synthetic lubricants ( oils and greases) used in many things from spaceships to computer chips. It is a chemical polymer belonging to the ether family that was patented by the chemical manufacturing giant DuPont. It is based on polyhexafluoropropylene oxide (somewhat similar to PTFE), thermally stable, nonflammable (even in liquid oxygen), nontoxic, and insoluble in water, acids, bases, and most organic solvents. It has very low vapor pressure and can be used between about -60 and +316 to +399 °C. It is highly resistant to ionizing radiation, making it useful for aerospace and nuclear industry. It can withstand extreme pressure and high mechanical stress. ...more on Wikipedia about "Krytox"
Lanolin, also called wool wax, wool fat, or wool grease, a greasy yellow substance from wool-bearing animals, acts as a skin ointment, water-proofing wax, and raw material (such as in shoe polish). ...more on Wikipedia about "Lanolin"
A lubricant (colloquially, lube, although this usually refers to personal lubricants) is a substance (usually a liquid) introduced between two moving surfaces to reduce the friction and wear between them. An understanding of how lubricating systems work is crucial to the selection of a lubricant for a particular application. Any surface contains irregularities, even when polished to a mirror finish. These irregularities may not be visible, except under a microscope. A lubricant provides a protective film which allows for two touching surfaces to be separated, thus lessening the friction between them. ...more on Wikipedia about "Lubricant"
Mineral oil or liquid petrolatum is a by-product in the distillation of petroleum to produce gasoline. It is a chemically inert transparent colorless oil composed mainly of alkanes and cyclic paraffins, related to white petrolatum. Mineral oil is a substance of relatively low value, and it is produced in very large quantities. Mineral oil is available in light and heavy grades. ...more on Wikipedia about "Mineral oil"

Molybdenite is a mineral of molybdenum disulfide, Mo S2. Similar in appearance and feel to graphite, molybdenite has a lubricating effect that is a consequence of its layered structure. The atomic structure consists of a sheet of molybdenum atoms sandwiched between sheets of sulfide atoms. The Mo-S bonds are strong, but the interaction between the sulfur atoms at the top and bottom of separate sandwich-like tri-layers is weak, resulting in easy slippage as well as cleavage planes. ...more on Wikipedia about "Molybdenite"
Molybdenum disulfide, also called molybdenum sulfide or molybdenum(IV) sulfide, with the formula MoS2, is a black crystalline sulfide of molybdenum. It occurs as the mineral molybdenite. It is insoluble in water and unreactive toward dilute acids. Its melting point is 1185 °C, but it starts oxidizing in air from 315 °C, limiting the range of its use as a lubricant in the presence of air between the temperatures of -185 and +350 °C; in nonoxidizing environments it is stable up to 1100 °C. ** ...more on Wikipedia about "Molybdenum disulfide"
Motor oil is a type of liquid oil used for lubrication by various kinds of motors, especially internal combustion engines. Other benefits from using motor oil include cooling by carrying heat away from moving engine parts and often include cleaning and corrosion inhibition in internal combustion engines. The major fraction of the majority of motor oils is derived from crude oil (see Petroleum). ...more on Wikipedia about "Motor oil"

Penetrating oil is very low viscosity oil. It can be used to free rusted mechanical parts (such as nuts and bolts) so that they can be removed, because it can penetrate into the narrow space between the threads of two parts. It can also be used as general purpose lubricant, or to clean or prevent corrosion. ...more on Wikipedia about "Penetrating oil"
Petroleum (from Greek petra – rock and oleum – oil or Latin petra – rock and oleum – oil ), crude oil, sometimes colloquially called black gold, is a thick, dark brown or greenish liquid. Petroleum exists in the upper strata of some areas of the Earth's crust. Another name is naphtha, from Arabic naft or nafata (to flow). It consists of a complex mixture of various hydrocarbons, largely of the alkane series, but may vary much in appearance, composition, and purity. Petroleum is used mostly, by volume, for producing fuel oil, which is an important " primary energy" source ( IEA Key World Energy Statistics ). Petroleum is also the raw material for many chemical products, including solvents, fertilizers, pesticides, and plastics. ...more on Wikipedia about "Petroleum"

Silicones, or polysiloxanes, are inorganic polymers consisting of a silicon- oxygen backbone (...-Si-O-Si-O-Si-O-...) with side groups attached to the silicon atoms. Certain organic side groups can be used to link two or more of these -Si-O- backbones together. By varying the -Si-O- chain lengths, side groups, and crosslinking, silicones can be synthesized into a wide variety of materials. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common type is linear polydimethylsiloxane or PDMS. The second largest group of silicone materials is based on silicone resins, which are formed by branched and cage-like oligosiloxanes. ...more on Wikipedia about "Silicone"
Silicone resins is a type of silicone material which is formed by branched, and cage-like oligosiloxanes with the general formula of RnSiXmOy, where R is a non reactive substituent, usually Me or Ph, and X is a functional group H, OH, Cl or OR. These groups are further condensed in many applications, to give highly crosslinked, insoluble polysiloxane networks. ...more on Wikipedia about "Silicone resin"
