What is the difference between viscosity and viscosity index?
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity

How would you define viscosity - index?
Viscosity index is a measure of how an oil's viscosity changes with temperature. Higher viscosity index oils are more resistant to changes in viscosity with temperature, making them perform more consistently across a range of temperatures.
What is the range viscosity index for a SAE 40?
The viscosity index (VI) for an SAE 40 oil typically ranges from 95 to 115. This index measures how much the viscosity of the oil changes with temperature; a higher VI indicates that the oil maintains its viscosity better across temperature variations. SAE 40 oils are commonly used in applications requiring high-temperature performance, such as in certain engines and industrial machinery.
How do you increase the viscosity index of kerosene oil?
Heat it up a little to evaporate the volatile burning elements
How do you manufacture 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.

What is the relationship between viscosity and refractive index?
There is no direct relationship between viscosity and refractive index. Viscosity relates to the resistance of a fluid to flow, while refractive index is a measure of how much light bends as it passes through a substance. However, the refractive index of a substance may change with temperature, which can in turn affect its viscosity.
How do you measure gel formation index of bentonite?
The gel formation index of bentonite is typically measured by mixing a specific amount of bentonite with water and allowing it to hydrate for a set amount of time. The viscosity of the resulting gel is then measured using a viscometer, with higher viscosity indicating greater gel formation. The gel formation index can be calculated by comparing the viscosity values of the bentonite gel to a standard reference sample.
Name 3 oil additives and state the purpose of each?
Three oil additives include viscosity index improvers, alkaline compounds, and friction modifiers. Viscosity index improvers reduce changes at high temps, the compounds prevent acid erosion, and the modifiers form protective films on engine parts.
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.
What is the effect of dilution on viscosity of oil?
dilution will reduce the viscosity The effect of dilution on viscosity of oil is that it will decrease.
