API motor oil quality marks—the API Service Symbol “Donut” and the Certification Mark “Starburst” for products meeting API motor oil standards. Read on about what you need to read on the labels. API SERVICE CLASSIFICATION FOR PASSENGER CAR ENGINE OIL. Read the Labels! What does viscosity mean to you when selecting a mold rubber? Maple Syrup or Motor Oil (SAE 30), 150 - 200, centipoise (cps) Temperature will affect the viscosity of most materials, these estimated numbers are based on measurements Dec 4, 2019 What does 5W-30 mean? Well, simply put, the numbers mean viscosity and that seemingly-out-of-place W stands for winter. Broken down, it May 28, 2018 This would be the “5W” in Amsoil XL 5W-30 Synthetic Motor Oil. should understand what the numbers identifying different viscosities mean. Lets look at what oil specs actually mean and particularly the higher number which is in fact the oils SAE number (the "w" number is in fact the cold crank viscosity Jan 1, 2009 When your van was manufactured, the top-of-the-line motor oil was rated SG, so that's what Ford called for. TOM: Well, since then, oils have
A popular oil, such as 10W-30, performs like two oils in one when it comes to engine lubrication. At colder temperatures it delivers a 10W-grade oil performance, while at higher temperatures it performs like a 30-grade oil. This provides engine protection at both ends of the temperature spectrum,
To most people, engine oil is just one of those substances that goes towards keeping your What does motor oil do? What do the numbers and letters mean? For starters, in oil nomenclature, “W” does not stand for “Weight”. the oil is cold, so the numbers after the “W” don't relate to the numbers in front of the “W”. Dec 11, 2017 But be careful: transmission oils have a different SAE numbers. For example, a 75W90 transmission oil doesn't have a higher viscosity than a Will thicker oil damage my engine? Is it important to change oil and how often should I do this? You should change What does “W” mean in oil numbers?
For starters, in oil nomenclature, “W” does not stand for “Weight”. the oil is cold, so the numbers after the “W” don't relate to the numbers in front of the “W”.
Jul 31, 2017 What do these numbers mean? What does SAE 5W-30 mean? The short answer: The numbers represent the viscosity of the oil and the W stands for system for grading motor oils according to their viscosity characteristics. 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 Jan 16, 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
The scale rates oil from a low of 5 to a high of 50. As you’ve probably noticed, most automobile motor oils have two numbers. These are multi-grade oils, which means they are non-Newtonian fluids.
Apr 3, 2013 An example of that would be an SAE 50. Thinner (Lower Viscosity) oils are assigned a lower number like SAE 10. Multi-Grade Motor Oil. To make
Dec 4, 2019 What does 5W-30 mean? Well, simply put, the numbers mean viscosity and that seemingly-out-of-place W stands for winter. Broken down, it

The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. 5w30 is for cold weather, the letters and number mean the weight of the oil 5 is lighter than 10 therefore 5w30 should be ran in weather below 30 degrees it can circulate better and your car will start better. 10w30 is for hotter weather so it keeps the engine cooler.
