A considerable amount of such fuel is mixed with the crankcase oil and dilutes it, thus affecting its lubricating property. The viscosity of an oil is usually as the time in seconds that it takes for a given amount of the oil to flow by gravity through a standard sized orifice at a given temperature. 26. Lubricating oils are composed of 80–90% petroleum hydrocarbon distillate with 10–20% additives to impart specific properties to the oil. If it is an engine, the lubricating oil serves actually three main functions. In this article, you’ll learn what are the different properties of Lubricants (lubricating oil) with Explanation. Lubricating oil must be stable physically at the lower and the highest temperature between which the oil is to be used. Viscosity: A lubricant’s “internal resistance to flow.”  Higher viscosity lubricants are thick and don’t flow, while lower viscosity lubricants have a closer consistency to water and do flow. At the lowest temperature, there should not be any separation of solids, and at the highest temperature, it should not vaporise beyond a certain limit. However, kerosene is still used by glass cutters to facilitate the smoothest penetration of the glass surface, lubricating the contact of blade and glass. This property is … Viscosity: A lubricant’s “internal resistance to flow.”. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule. It should not contain dust and dirt particles. While there are other properties to consider when choosing a lubricant, these are often considered the most important.
