Have you ever stared blankly at a wall of motor oil in the store, wondering what all those numbers and letters mean? SAE 5W-30, 15W-40, 10W – what does it all Jul 29, 2019 Have you ever wondered what the numbers printed on motor oil bottles mean? We explain the origins and meaning behind motor oil viscosity Feb 21, 2019 As with monograde oils, the 'W' still means 'winter'. The number before this 'W' represents the winter viscosity grade – the engine's capacity to The more viscous, the slower it will move. Apple juice has low viscosity, cold honey has high viscosity. So what do the numbers mean? The number preceding the The higher the Viscosity Index number the less thinning and thickening the motor oil has. In other words, high number good, low number bad. Low numbers When you buy engine oil, it's important to know the oil's viscosity, a property That means that an organization called the Society of Automotive Engineers The viscosity rating is the number of seconds rounded to the nearest multiple of ten.

Pyrolysis bio-oil viscosity varies widely depending on the biomass types and water This small number means that laminar flow exists in almost all microfluidic Numbers you find on different oil cans, such as SAE 30 or SAE 10W-30, are viscosity or weight numbers that indicate the thickness of the oil. The higher the number, the thicker is the oil. As earlier mentioned, SAE stands for Society of Automotive Engineers. A viscosity “grade” is just like 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. Viscosity grades are similar. When you see an oil that’s rated SAE 30, this translates into an engine oil that has a viscosity between 9.3 cSt and 12.5 cSt at 212 degrees F. Multigrade Oils

The Society of Automotive Engineers (SAE) assigns a viscosity number, or weight, to oil based on its flow at 210 degrees F, which is roughly the standard operating temperature for most motors. The higher the number, the thicker or slower flowing it is, which changes the nature of how it coats internal engine components and protects against heat and friction .

The oil’s viscosity is defined in the main by the size of the molecules. The larger the molecule structures, the thicker, or higher, or heavier the viscosity. The size and structure of mineral oil molecules vary, so the average molecule size dictates the viscosity, whereas the synthetic oil manufacturing process results in consistently sized molecules of an identical structure. The viscosity index refers to how much the viscosity of a lubricant changes due to fluctuations in temperature. An oil’s VI is measured at 40°C and 100°C. IF a liquid’s viscosity does not change much between these temperatures, it will have a higher VI and vice versa. You can find the VI of an Amsoil motor oil on its product data sheet.

The higher numbers of a gear oil (e.g., 75W-140) do not mean that it has higher viscosity than an engine oil. In anticipation of

confused with engine oil viscosity. The higher numbers of a gear oil (e.g., 75W- 140) do not mean that it has higher viscosity than their viscosity characteristics. What do the SAE numbers on a container of motor oil mean? To properly answer that question a bit of history is required. Motor oil is like every other fluid in that

The number following the W designation is the viscosity of the oil at 212 deg F. Again, the higher the number the more viscous the oil is. The lower the number the less viscous the oil is. The oil’s viscosity is defined in the main by the size of the molecules. The larger the molecule structures, the thicker, or higher, or heavier the viscosity. The size and structure of mineral oil molecules vary, so the average molecule size dictates the viscosity, whereas the synthetic oil manufacturing process results in consistently sized molecules of an identical structure.
