Car oil numbers explained
16 Jan 2019 In a nutshell, the numbers before and after the W represent viscosity. The letter “ W” itself stands for Winter. As you may know, viscosity means the Car care FAQs Why do you have to change your motor oil on a regular basis? Motor oil breaks down over time. What does a viscosity index number mean? Here we explain what descriptions like 0W-20 and 5W-40 actually mean. Engine Oil Viscosity Grades. What do the viscosity numbers mean? 21 Feb 2019 What do these viscosity grades mean? As with monograde oils, the 'W' still means 'winter'. The number before this 'W' represents the winter 17 Aug 2018 So you want to topup your car's engine oil and you want to do it the jargon means but just want to make sure you get the right motor oil for your The large numbers on a bottle of oil like 5W30 or 10w40 refer to its viscosity. 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. They perform 28 May 2018 Meanwhile, the “30” in 5W-30 indicates the fluid's ability to flow at a vehicle's normal operating temperature, which is 100°C. If this number is
The numbers without the W are all tested at 210° F or 100° C which is considered an approximation of engine operating temperature. In other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210° (100° C). The difference is when the viscosity is tested at a much colder temperature.
18 Apr 2018 This article describes the processes of degradation of five engine oils belonging to the same The concept, the means, and methods of measuring engine oil quality based on The number of kilometers traveled by each car. 7 Aug 2018 This means that getting the right oil for your car is more important than Grade – the viscosity of your engine oil, signified by two numbers that #4 Oil Weight and Viscosity -- What Those Numbers Mean. Different engines require different engine oils with varying weights and viscosity ratings. VW 507.00, VW 504.00, etc: Volkswagen Motor Oil Specifications Explained ( These numbers may seem incredible to American car owners but motor oil 9 May 2014 Tech 101 – What oil viscosity ratings mean | Meeting the Transportation and plays a small part in the overall fuel economy of your vehicle. the oil's viscosity at the lowest recommended temperature, the higher number 11 Oct 2013 passenger car engine oil five grades go from “20” to “60” in steps of 10, without the W. In general, higher numbers mean higher viscosities. The lower the "W" number the better the oil's cold temperature/cold start performance. The 40 in a 10w-40 simply means that the oil must fall within certain viscosity limits at 100°C. This is a fixed limit and all oils that end in 40 must achieve these limits.
VW 507.00, VW 504.00, etc: Volkswagen Motor Oil Specifications Explained ( These numbers may seem incredible to American car owners but motor oil
The lower the "W" number the better the oil's cold temperature/cold start performance. The 40 in a 10w-40 simply means that the oil must fall within certain viscosity limits at 100°C. This is a fixed limit and all oils that end in 40 must achieve these limits. Oil weight, or viscosity, refers to how thick or thin the oil is. The temperature requirements set for oil by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high). You can easily predict the behavior as well as the design of a mechanical system if you have detailed knowledge of oil viscosity. What Do Oil Viscosity Numbers Mean. 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. The numbers represent the viscosity of the oil and the W stands for WINTER. The long answer: The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics. 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 . 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 numbers without the W are all tested at 210° F or 100° C which is considered an approximation of engine operating temperature. In other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210° (100° C). The difference is when the viscosity is tested at a much colder temperature.

2 Aug 2019 No one really thinks about the different levels of oil thickness or how much of an influence hot and cold temperatures have on the oil. If you
18 Apr 2014 When comparing multi-grade oils, the lower number represents the oil's viscosity at the lowest recommended temperature, the higher number
We explain what the label on your bottle of oil means, the viscosity, what the back to basics but I'm constantly surprised by the number of people who do not know, 2) The viscosity (i.e. 10w40, 5w30 etc for Motor oils and 80w90, 75w90, etc 14 Feb 2019 Viscosity means a fluid's resistance to flow. In motor oil, it's rated at zero degrees Fahrenheit (represented by the number preceding the "W" [for 16 Jan 2019 In a nutshell, the numbers before and after the W represent viscosity.
