Remember that refrigerant itself has very low viscosity. Solutions of oil and refrigerant have a viscosity between that of the oil and that of the refrigerant. As more refrigerant dissolves in the oil, the solution becomes less viscous.
The Element Earth. The earth signs are Taurus, Virgo, and Capricorn. The earth signs are stable and practical, and they are sometimes thought of as stubborn. They are concerned with the mundane details of the world, and what really exists. They can have trouble with non-tangible ideas, however.
Most Taurus people are attracted to the other two earth signs: Virgo and Capricorn. All these three signs are known for their pragmatism and loyalty and their compatibility is well known. With Virgoans they share the same realism and resourcefulness, while the ambition of Capricorns will always represent a role model for them.
