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. Mass fraction (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Mass_fraction_(chemistry)

   A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because the unit "%" can only be used for dimensionless quantities.

4. Western Canadian Select - Wikipedia

   en.wikipedia.org/wiki/Western_Canadian_Select

   Western Canadian Select (WCS) is a heavy sour blend of crude oil [1] that is one of North America's largest heavy crude oil streams [2] and, historically, its cheapest. [3] It was established in December 2004 as a new heavy oil stream by EnCana (now Cenovus), Canadian Natural Resources, Petro-Canada (now Suncor) and Talisman Energy (now Repsol Oil & Gas Canada).

5. Blend time - Wikipedia

   en.wikipedia.org/wiki/Blend_time

   Blend time, sometimes termed mixing time, is the time to achieve a predefined level of homogeneity of a tracer in a mixing vessel. Blend time is an important parameter to evaluate the mixing efficiency of mixing devices. [1] In order to make this definition valid, the tracer should be in the same physical phase (e.g. liquid) as the bulk material.

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. 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 ...

9. Two-stroke oil - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_oil

   The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered engines.
