What is the pour point of lubricating oil?
It varies with the oils viscosity.
Which property of lubricating oil affects heat generation in the engine?
viscosity
What property of lubricating oil affects heat generation in the engine?
viscosity
Why graphite is better than oil for lubricating the moving parts of hot machinery?
because its viscosity is not too low or too high its moderate
What is the difference between single viscosity oil an mulit-viscosity oil?
Single viscosity is high quality oil. Mulit-viscosity oil is used for in the winter.
How do you Engine Oil?
Well Engine oil manufacturers keep the manufacturing techniques secrets with each others. Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil, with additives to improve certain properties. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule. One of the most important properties of motor oil in maintaining a lubricating film between moving parts is its viscosity. The viscosity of a liquid can be thought of as its "thickness" or a measure of its resistance to flow. The viscosity must be high enough to maintain a lubricating film, but low enough that the oil can flow around the engine parts under all conditions. The viscosity index is a measure of how much the oil's viscosity changes as temperature changes. A higher viscosity index indicates the viscosity changes less with temperature than a lower viscosity index.

Can car diesel be used as a heating oil?
It has a very similar viscosity to heating oil but is thinner, It does not have the same lubricating quality as heating oil and will burn out the oil pump prematurely, so not recommended.
What is meant by the term viscosity when used in describing magma?
The ease with which it flows or how thin or thick it is. the more solid it is the higher the viscosity. As in Oil the thicker it is the higher the viscosity machine oil low viscosity, gearbox oil high viscosity.
Why is the pickup in your 150cc motorcycle decreased after running for 100 km?
The heat buildup causes metal expansion and lowers viscosity( of lubricating oil).
Is lubricating oil volatile?
Lubricating oil is NOT volatile.
Why low viscosity motor oil used in the winter and high viscosity motor oil used in the summer?
Low viscosity oil flows easier when it is cold but become thinner when it is hot.
