The choice of engine oil plays a critical role in determining the engine performance and fuel economy. It can also affect the very quality and life of the engine. Viscosity is often considered as a critical factor when choosing the right oil. If you require an oil change, bring your car in at the Greensboro auto repair center.
Understanding the viscosity of the oil for any vehicle is challenging. It feels a bit like math class when you look at row after row of oil boilers plastered with algebraic numbers and letters. What do they mean by the way? To get a clear understanding, one should always follow the vehicle owner's manual. It helps you determine the correct viscosity grade, engine oil specification, and oil drain interval. More about Engine Oils: Remember, an engine is made of with the right balance of base oils and additives. Base oil performance is typically divided into mineral or synthetic or a combination of the two, which is called synthetic blend. Additive performance is defined by the quality of the additive and how much goes into the product. Selecting the right combination of base oil and additive is the ultimate challenge. Now, the base oil is essential in determining viscosity. It is the primary carrier for engine oil, accounting for 80-90% of the formula. What viscosity is all about? Well, viscosity is nothing but the resistance of the oil to flow. In simpler words, it refers to how well a lubricant flows at a given temperature. The quick the oil flows, the lower its viscosity, and the grade assigned to it. It means high viscosity oils flow more slowly and come with a higher grade. What is Viscosity Grade? A viscosity grade is just equivalent to a grade in school that denotes a range of numbers. For example, an A is a 90-100, a B is an 80-89, etc. If the oil is rated SAE 30, it means that the oil has a viscosity between 9.3 CST and 12.5 CST at 212 degrees F. What is Viscosity Index? The rate of change of viscosity of the oil between two temperatures is known as its Viscosity Index. Earlier, vehicle owners had to change their oil depending on the season and shifted to higher viscosity oils during the summer. An oil change is a complicated task. Take your car to the nearby car repair shop Greensboro NC for an oil change to avoid complications.
