Motor oil is very important in order for your car to operate safely and effectively. How important is motor oil in the everyday operation of your vehicle? Without proper lubrication and cooling from motor oil your car’s engine will quickly overheat and spark causing damage to your engine and vehicle. This article will describe some of the characteristics of motor oil. It will also contain reviews of top motor oil products. The reviews will include basic information about the product that you should find useful and will contain product pros and cons.
As mentioned above in the introduction the main purpose of motor oil is to lubricate the engine’s moving parts and to keep them cool. Motor oil also helps to keep your engine parts clean. It also helps to prevent rust and deposits from forming on your engine which can hamper engine operation. So what are some of the important characteristics of oil that you should pay attention to? One characteristic is viscosity.
Viscosity is a measure of how resistant a liquid is to flow. Viscosity is important because you want motor oil to stay in between your engine and not flow out of your engine. Motor oil becomes thicker as the temperature decreases and becomes thinner as the temperature increases.
This is why motor oil must be viscous, because otherwise it will not maintain a layer of lubrication in your engine. When shopping for motor oil the number before the W represents how viscous the oil is during warm weather and the second number represents how viscous the oil is during cold weather. When purchasing motor oil, you should purchase a product that has the minimum viscosity that your car requires.
The higher the numbers a motor oil has the more resistant it will be to thickening and thinning. Another important characteristic that you should pay attention to is additives the motor oil has. Additives include things such as detergents, friction modifiers, antioxidants, rust inhibitors and anti-wear agents. Additives remove deposits, increase viscosity, prevent rust, protect metal parts, and can improve fuel economy.
