What do the numbers mean in engine oil
22 May 2018 What do those numbers mean? The Society of Automotive engineers came up with a system to measure oil viscosity with a number. What are motor oil viscosity ratings? A car in Death Valley would need a higher number to keep the oil from thinning out too much. The second number after A: That's the viscosity range of the oil, i.e., how thick it is. 20W means that this oil behaves exactly like a 20 weight oil at 0F, and behaves like a thicker 50 weight oil 3 Apr 2013 Picking out the proper grade motor oil is becoming increasingly difficult.

Viscosity, by definition, is an oil's resistance to flow and shear. With oil, like syrup, as you increase the temperature, the viscosity lowers, meaning it flows faster, For domestic use, engine life is important, and in the main you should adhere to The base oil in use in a multi-grade (aka multi-seasonal) is the first number 14 Aug 2017 While some manufacturers would prefer the word synthetic to only apply to oils An oil's group number is dependent on the base oil properties used to derive it. Consider the creation process of a conventional 5W-30 motor oil. This means at extremely low temperatures, it may be thick, and at high
