Edmunds explains what the numbers on motor oil mean, and how to select the best one for your car. EDMUNDS VIDEO http://www.Edmunds.com is a car-shopping web Motor Oil: What Do Grades Mean For Your Engine. (Michael Keaton) in the 1983 movie Mr. Mom, so it should work for you, too, when it comes to selecting the right motor oil grade, right? Simply pick a number? Nope! Just like with electricity, when it comes to car oil, numbers matter—especially if you want to protect your engine. What Does the "5W-40" in Motor Oil Mean? by Jerry Romick . Motor oil provides lubrication to a vehicle's engine, keeping the moving parts from overheating due to friction. It also transfers heat from the combustion cycle, helps keep the engine clean by suspending combustion by-products and protects the engine from oxidation. The two numbers Motor oil 10W-30. What does the numbers mean? I have a car 1.8 litres, 4 cylinders, 60000 miles. Before that I used 5W-30, but now found a box of 10W-30 in my garage from another car. Is it ok if I use it for my car. I don't have a manual for the car, and I don't know what the numbers mean. What Do Gear Oil Viscosity Numbers Mean? by John Smith . As mentioned previously, gear oil viscosity numbers are not directly comparable to engine oil viscosity numbers. For example, 75W-90 gear oil is about the same viscosity as 10W-40 engine oil; 80W-90 is about the same as 20W-40.
10 Dec 2014 That designates the oil as a winter grade. Those numbers that don't have the W were tested at 210°F, the approximate temperature of an engine 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 WHY CHOOSE A 0W (ZERO-W) VIS-GRADE MOTOR OIL? What do the numbers mean on motor 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. 9 May 2017 The number on the bottle is the oil's Society of Automotive Engineers (SAE) standard viscosity rating or 'weight'. Very simply, the higher the 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 23 Aug 2012 So, what do these numbers mean? Engine oil grade. Photo credit: Thinkstock. Choosing the right grade of motor oil The viscosity grade (for example, 5W-30) tells you the oil's thickness, or viscosity. A thin oil has a lower number and flows more easily, while thick oils have a In regard to multigrade oils, the first number in the code, such as 10W in SAE 10W-30, means that the oil can still be pumped by the engine at a temperature as
26 Oct 2018 There is always some sort of confusion among motorcycle riders as to what engine oil to use. Whether it's what brand to use or how frequently 15 Jun 2019 In this article, you will learn everything about engine oils. In this article, you will learn about the meaning and a lot more about the SAE Motor oil. The number mentioned after “W-XX” indicates the oil viscosity measured at What do the numbers and letters mean using the example SAE 20w/50, API - SJ/CF The second part,CF, is a diesel engine oil rating, 'C' being diesel and 'F' The 'W' rating can be 5, 10, 15 or {20;} lower numbers mean the oil is thinner in cold temperatures, necessary for icy climates. The second 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 17 Aug 2018 So you want to topup your car's engine oil and you want to do it yourself The large numbers on a bottle of oil like 5W30 or 10w40 refer to its viscosity. Using synthetic oil does not mean you can extend the amount of time 10 Dec 2014 That designates the oil as a winter grade. Those numbers that don't have the W were tested at 210°F, the approximate temperature of an engine
This leaves them still wondering what the viscosity numbers really mean on a bottle of motor oil. Simply put, viscosity is the oil's resistance to flow or, for the layman, an oil's speed of flow as measured through a device known as a viscometer. The thicker (higher viscosity) of an oil, the slower it will flow. What does 5W-30 actually mean Not all of us get to service our own cars. In fact, most of us don’t even know what is under the hood of our car, let alone the type of oil that is in our engine. Understanding Oil Viscosity: What Do Those Numbers On The Bottle Mean? Understanding Oil Viscosity: What Do Those Numbers On The Bottle Mean? 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. Viscosity (a fluid's resistance to flow) is rated at 0° F (represented by the number preceding the "W" [for Winter]) and at 212° F (represented by the second number in the viscosity designation). So 10W-30 oil has less viscosity when cold and hot -- Q U E S T I O N: Motor oil: SAE 30, 10W-40, 20W-50. What do all those number and letters mean? — Danny S. A N S W E R: Many thanks for your query. What do the letter and numbers mean on motorcycle oil bottles (e.g. 10w40)? As well as being defined by their type (e.g. Synthetic, Semi-Synthetic or Mineral), motorcycle engine oil is also defined by it’s thickness (or viscosity). The viscosity rating is normally displayed on the oil container by a series of 2 numbers separated by […]
