Actually the oils that are designed for vehicle engines does in fact flow easily.
Try this test. take a tablespoon of 5-30 oil and pour it on a piece of glass that is laying flat. Note how far it will travel / migrate on the surface. When the oil is heated, it travels faster, further and better to keep a car engine lubricated.
Viscosity is "resistance to flow". Anything that doesn't flow very easily has a higher viscosity level. Oil would be example.
Many crude oils flow very easily, but this is not true in all cases. I will address the problem of oil flowing from the bottom of the well to surface. Sometimes, the reservoir rock is too tight (insufficient permeability) to allow the oil to flow at substantial rates. The well must be stimulated, frequently with acid or hydraulic facturing. The oil may be too viscous to flow. This is a common problem if the oil density is less than 15 degrees API. Crude oil is a complex mixture of many compounds. Strong cohesive forces (atttractive forces among molecules) result in high viscosity. The oil may be heated using steam to reduce the viscosity. Steam flooding is common in California. Wax and asphaltene precipitation may also prevent oil from flowing. You may find more links on this topic by doing an internet search.
A solid does not flow easily.
A material that can easily flow is called a fluid.
The purpose of perforation depending on what one is talking about. In the case of oil well, the purpose of perforation is to allow the oil or gas to flow more easily to the wellbore to get it out of the ground.
Because if it was filled with oil nothing would be able to dissolve. With the water all things can dissolve.
"Insulator" means that electrical charge can NOT flow through it easily.
No. That oil is too thick and it wont flow to the top of the motor very well. It may work for a while but you will be slowly wearing out the lifters, etc. I wouldn't do it.
The numbers refer, mainly, to the viscosity of the oil and to the temperature range at which is should be used. The oil with the lower number would be less viscous and flow more easily in lower temperatures.
A flow station is a place where oil directly from the oil well flows to for primary treatment and control
Higher viscosity oil does not flow as easily as lower viscosity oil, and therefore would not leak as badly. On the other hand, parts of the engine may not be getting enough oil and may be damaged. You are better off just fixing the leak.
