Oils are assigned numbers based on the viscosities displayed at certain temperatures. It has more recently been recognized that oil viscosity at colder  13 Aug 2018 Knowing what the numbers mean can help riders choose the best oil for their bike. The first number in an oil weight is its winter weight, or how  The lower the number, the thinner the oil. For example, a rating of 5W-30 means that the oil will have a viscosity rating of 30 at 212℉, or 100  28 Nov 2018 Before we start deciphering the numbers on these oil viscosity ratings, let us This means that if the engine is cold, the engine oil should not  What do the numbers and letters mean using the example SAE 20w/50, API is a viscosity numbering system used to identify the 'thickness' of an oil or it's  What do these viscosity grades mean? As with monograde oils, the “W” still means “Winter”. The number before the W represents the winter viscosity grade. 20 Jul 2012 These oils have two numbers in its viscosity grade. You are probably familiar with 5W-30 or 10W-40, they are examples of these types of oils.

What do the numbers and the "W" mean? W does not stand for weight, it stands for Winter. The SAE classifications characterized the viscosity at low and 

31 Jul 2017 The short answer: The numbers represent the viscosity of the oil and the W stands for WINTER. The long answer: The Society of Automotive  What does the "w" in a grade of motor oil stand for? The "w" in motor oil stands for winter. The first number in the oil classification refers to a cold weather viscosity. 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   18 Apr 2015 As far as the numbers, use what your vehicle manufacturer recommends. There is a reason your manufacturer recommends a viscosity, the 

The first number, 5 or 10 in this case, is a measurement of how easily the oil pours That means switching to a higher viscosity oil can do more harm than good,

You are probably familiar with 5W-30 or 10W-40, they are examples of these types of oils. 27 Jan 2016 The viscosity is what determines the thickness of the oil. A lower number means a thinner viscosity, and a higher number dictates a thicker 

5 Dec 2016 There are those who swear by using heavier-weight motor oil during summer The higher the number, the thicker the viscosity at operating temperature. Oil Does this mean that you should abandon your time-tried habit of 

What do the viscosity numbers mean? The viscosity of an oil is measured by its resistance to flow. There are two numbers that define the viscosity of an oil. The W or winter number is important for low tem perature performance. Referring to the J300 table, to list a multi-viscosity oil as a 10W the Cranking (cP) max at  The numbers indicate the oil grade, which is a measure of its viscosity. A layman can think of viscosity as a liquid's thickness. Consider the difference between 

4 May 2017 In this article, we'll talk about oil viscosity, why it's important, and its various these single-grade oils provided the ideal protection that modern oils do The second number after the W refers to the viscosity characteristics a motor oil Be assured that our range of choices means you're guaranteed to find
