Engine oil numbers what do they mean

What is “viscosity” and why does it matter for your engine's oil? The lower the “ W” number, the better the oil will perform at a cold temperature. For example, a rating of 5W-30 means that the oil will have a viscosity rating of 30 at 212℉, 

Over time, your engine will pick up dirty deposits, meaning it won't last forever. If you're wondering how often you should change your oil, check your car's manual. The second number is the viscosity of the oil when tested at temperatures  What do these numbers mean? 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 thickness of a fluid. In the case of motor oil, it is the thickness of the oil under certain temperature conditions. The number to the left of the W refers to the oil viscosity when the temperatures are low. The number to the right of the W refers to the oil viscosity at hotter temperatures. If the first number is Higher viscosity numbers mean a greater resistance to flow and greater friction between the oil and the parts it lubricates. The SAE scale ranges from 5 up to 50, with 50 being the thickest. The optimal viscosity depends on the operating temperature and the engine structure. Automotive Oil What do the oil numbers 10W-30 mean? Your engines rotating parts are protected from heat and friction by a thin layer of oil. Understanding the viscosity ratings and detergents used in today's modern oils is critical to keeping your engine running. Oil weight is a term used to describe the viscosity of an oil, which means how well it flows at a specific temperature. 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. Just like with electricity, when it comes to car oil, numbers matter—especially if you want to protect your engine. Motor Oil Viscosity Oil “weights” or grades—such as 10W-30—are actually a numerical coding system developed by the Society of Automotive Engineers (SAE) to grade oils based on their viscosity. If your car calls for a 5W-30 or a 10W-30, but you live in an extremely cold climate, then you can use a 0W-30; choosing a “0W” means the oil will still pump at -40°F, and the “30” means the oil will provide the same high temperature viscosity. Lower viscosity “0W” oils can also help provide better fuel economy,

Just like with electricity, when it comes to car oil, numbers matter—especially if you want to protect your engine. Motor Oil Viscosity Oil “weights” or grades—such as 10W-30—are actually a numerical coding system developed by the Society of Automotive Engineers (SAE) to grade oils based on their viscosity.

Your vehicle shows engine oil life as a percentage. Percentage of remaining life, there is sometimes a letter and/or a number displayed-what do they mean? Simply put viscosity is a physical property of a fluid or gas that reflects it's tendency to flow. What do the SAE numbers on a container of motor oil mean? 18 Apr 2018 This article describes the processes of degradation of five engine oils belonging to the and methods of measuring engine oil quality based on the total acid number (TAN) The limit value of significance was set at 0.05. They are designed for a use in high performance gasoline and light duty diesel it is based upon the original ACEA A3 and ACEA B4 sequences that were of the engine oil, it was possible to combine ACEA A3/B4 with a number of other  Not everything you hear about motor oil is true. There are many myths surrounding motor oil, some of which you may have even been told were true by a Just because your engine oil is no longer that fresh, amber color doesn't mean that it needs to be changed. 'Myths of Motor Oil Numbers on package Banner'. The numbers that come before the W refer to the product's cold grade, i.e., To find out which oil and which viscosity you should use for your vehicle, refer to the   Over time, your engine will pick up dirty deposits, meaning it won't last forever. If you're wondering how often you should change your oil, check your car's manual. The second number is the viscosity of the oil when tested at temperatures 

31 Jan 2013 These numbers refer to viscosity with the lowest numbers representing the thinnest, and therefore the "thinnest" oil. The “W” stands for “Winter,” 

Over time, your engine will pick up dirty deposits, meaning it won't last forever. If you're wondering how often you should change your oil, check your car's manual.

10 Dec 2014 Those numbers that don't have the W were tested at 210°F, the To interpret the viscosity 5W-30, it means that an SAE 5 motor oil can perform 

engine oil? What is synthetic engine oil? Learn from Shell why it's essential that you get your engine oil specification right. What do the oil numbers mean? Manufacturers label the engine oils they produce using codes and numbers that puzzle many car owners. Motor oil should feature: They are also divided into classes: B1 and B5 mean fuel economy, while В3 and В4 are regular products. Viscosity Significance. Why it is important to ensure that a petroleum product has a correct viscosity. 3 Oct 2013 What do all those numbers and letters mean, and are all brands the same? Are you puzzled about the types of motor oil available? Wondering  However Bardahl motor oil always means: exceptional good lubrication of your car, A number of problems arise if you do not observe the aging of oil. The first

31 Jul 2017 What do these numbers mean? What does SAE 5W-30 mean? system for grading motor oils according to their viscosity characteristics.

As for the numbers and what they mean, the numbers are the "viscosity" of the oil. Viscosity refers to the thickness of the oil, lower numbers are thinner, higher numbers are thicker. More appropriately the viscosity number is the amount of a given oil that can flow through a given oriface within a fixed amount of time which determines the viscosity number. The first number describes viscosity at low temperatures. The second number refers to viscosity at normal engine operating temperatures. Some examples: the “5” in a 5W-30 motor oil will protect an engine down to an air temperature of about -25 degrees Fahrenheit.
