Motor oil is used every day in every motor car traveling the highways. In addition, when one thinks of all the machinery that must be operated in all walks of life and the amount of oil required to run it the amounts are astronomical. Because of the different construction of these machines, it is important to make a Motor Oil Comparison before using it.
Another name for this product is engine oil. It not only is used for lubrication of an engine’s moving parts but also cleans it and carries away heat, which could cause damage. It’s used in all types of internal combustion engines. Without oil, engine parts would soon corrode or freeze up and be unable to move.
Three grades of motor oil are single, multiple and turbine. Each has a specific purpose for different types of machinery. The motor oil made from petroleum becomes thicker in cold weather and will form a wax after a period of time as compared to synthetic oil. This makes an engine hard to start and may require removing the oil and replacing it.
The grades in determine the weight of the oil and how smooth it will flow under certain conditions. The temperature of the engine, the type of weather it is being used in and other factors determine what the correct grade is. A motor, when it heats up, needs oil that will flow smoothly to keep it running efficiently.
Warming up one’s automobile in the morning or when starting out is for the purpose of warming up the oil and getting it flowing smoothly. Sitting in one position for a long period of time causes the oil to thicken and it needs to thin out to work correctly on the engine. There is no need to use a different weight oil during the year with the exception of air-cooled engines which must use one weight in summer and another in winter.
Viscosity is used to explain the resistance of a liquid to the flow. A high flow cools things such as the engine, pistons and other active parts of the automobile or equipment requiring the oil. It is recommended that any engine running hot needs thinner oil.
There are mineral and synthetic oils. Synthetic oils are devised in a laboratory and are almost pure while mineral oils come from pure petroleum and need to be treated to have the contaminants removed. While mineral oils thicken when cooled, synthetic oils do not. Therefore, synthetic oils are better when starting up an engine. When purchasing motor oil for any purpose it’s important to make a Motor Oil Comparison.
