1-Oils are liquid whereas grease are semi solid.
2- Grease are not affected by extreme temperatures, so they are commonly used in tools, machines and equipments. Oil, in room temperature, is liquid when subjected to extremely low temperatures, and tends to evaporate when subjected to extremely high temperatures. Oil is used by people in cooking, personal grooming, lubrication and so much more.
3-The viscosity of oil is low as compared to that of grease
4-Oil is extracted from animal fat, plant or crude oils. Grease is made up by mixing oil and thickener agent.
Emulsifier
Crude oil is readily separated into fractions one of which is gasoline. Lubricating oil is much more difficult.
bitumen, fuel oil, lubricating oil, diesel, kerosene, naphtha, petrol, refinery gas
Oil and grease stains are tough to remove from clothes because they resist water. The water in a washing machine works around the stain. Detergent makes it possible to remove oil and grease stains.
Grease
Lubricating Oil Is A Thick Fatty Oil (Especially One To Be Used For Lubricating Factory Machinery)
it's lubricating properties
engine oil is thick than hydraulic oil
20w-50 indicates Synthetic-oil
1 . By polishing the surfaces in contact 2 . By lubricating the surfaces in contact with oil or grease .
Lubricant oils include vegetable oil, silicone, fluorocarbons, polyolefins, grease, graphite, tungsten oil, molybdenum and mineral oils. Lubricating oils can be purchased in liquid or dry versions depending on their intended application.
Lubricating oil is NOT volatile.
Reduces friction between moving parts.
Lubricating oil is used to reduce friction between moving parts and to prevent damage due to excess heat. Lubricating oil also carries away sludge preventing the erosion of moving parts.
What are we actually asking here? Lubricating oil? The generator should come with a note as to what lubricating oil it uses, and different diesel engines in cars and lorries require different grades of oil. Or are we asking about fuel? Generators can be run off Red or Agricultural diesel as there is no Road Fuel Duty to pay.
One filters lubricating oil while the other filters fuel. The filtering media would be of a different type to filter out different contaminants
It ranges between 2.2 and 2.8.
