2. Synthetic oil - Wikipedia

   en.wikipedia.org/wiki/Synthetic_oil

   [3] Synthetic oils are also used in metal stamping to provide environmental and other benefits when compared to conventional petroleum and animal-fat based products. [4] These products are also referred to as "non-oil" or "oil free". A polyalcanoate [clarification needed] synthetic oil is widely used to lubricate pendulum clocks.

3. Oil additive - Wikipedia

   en.wikipedia.org/wiki/Oil_additive

   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]

4. Drilling fluid - Wikipedia

   en.wikipedia.org/wiki/Drilling_fluid

   Liquid fluids are composed of natural and synthetic material in a mixed state, [1] which can be of two types: [2] Aqueous; [3] usually with substances added that control viscosity, along with lubricants, for the inhibition of corrosive inhibitors, salts, and pH-control agents. [1] Oil; which could be usually using hydrocarbon oil, [1]

5. Polyolester - Wikipedia

   en.wikipedia.org/wiki/Polyolester

   Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12 , as these systems traditionally use mineral oil , [ 2 ] which HFC-134a does not ...

6. Viscosity models for mixtures - Wikipedia

   en.wikipedia.org/wiki/Viscosity_models_for_mixtures

   Elementary kinetic theory and simple empirical models [1] [2] [3] - viscosity for dilute gas with nearly spherical molecules; Power series [2] [3] - simplest approach after dilute gas; Equation of state analogy [3] between PVT and T P; Corresponding state [2] [3] model - scaling a variable with its value at the critical point

7. 3-in-One Oil - Wikipedia

   In 2000, the can was redesigned to look like the early 20th century oil can design, with a hemisphere base and tapered straight spout. [2] An advertisement in The Church Standard magazine (April 13, 1901, p 867) offers 3 in 1 Oil as a perfect polish for pianos. It claimed that the oil was "long lasting" and did not come off on the clothes. [3]
