What does the w mean in car oil
Quick google search for most simple answer, not as an engineering bla-bla. This is from TOTAL:: How is viscosity rated? The Society of Automotive Engineers (SAE) developed a scale for both engine (motor oil grades) and transmission oils. What are No, the "W" used in 5W30 for example does not mean weight. I always consider it means "Winter" or winter rated or cold weather related or whatever. It means pretty much what your quote says which is to say it's OK for winter use. 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). Oils meeting the SAE's low temperature requirements have a "W" after the viscosity rating (example: 10W), Also, the “W” stands for “Winter,” and refers to oil that maintains viscosity even in cold winter temperatures. The need for different grades of oil is readily apparent when the weather switches because the temperature has a dramatic effect on the viscosity of the oil. In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the "W" number the better the oil's cold temperature/cold start performance. Oils with two numbers, such as 5W-40, are multi-grade oils; they exhibit the characteristics of an oil with a viscosity rating of 5 at zero degrees Fahrenheit and the characteristics of an oil with a viscosity rating of 40 at 212 degrees Fahrenheit. The "W" indicates that the first number is the "cold" or "winter" rating. You might be asking what does the "w" mean. That means it is appropriate to be used in the winter. The reason oil pressure is important is that the clearances between bearing and crankshaft allow for pressurized oil to flow into those thousands of an inch and be the only thing to keep them from making contact.
For starters, in oil nomenclature, “W” does not stand for “Weight”. It stands for “ Winter” and that is the key to understanding viscosity grades. A 10W-30 is a
The oil you want depends on your vehicle and the environment in which you drive. What Does the W Mean? While many drivers think it means weight, the W in the A car in Death Valley would need a higher number to keep the oil from thinning out too much. The second number after the "W" indicates the oil's viscosity 18 Apr 2015 You might be asking what does the "w" mean. That means it is appropriate to be used in the winter. The reason oil pressure is important is that Here we explain what descriptions like 0W-20 and 5W-40 actually mean. The first number ends with the letter 'W', which stands for Winter. Thick, high viscosity oils are typically better at maintaining film strength to protect engines at high 10 Dec 2014 Car owner sometimes have a moment of complete bewilderment when it is If the viscosity has a W, this means that the viscosity of the oil has 21 Feb 2019 How do you know what the right viscosity grade is for your vehicle? oil with a high viscosity grade that is not marked 'W', meaning SAE 8, 12,
The W is the viscosity designed by the the Society of Automotive Engineers (S.A.E) of an oil required for Winter conditions.This is important because if you put in a 15W oil instead of say a 5W then the oil viscosity would be thicker and take longer to get to critical engine parts to prevent wear.
10 Dec 2014 Car owner sometimes have a moment of complete bewilderment when it is If the viscosity has a W, this means that the viscosity of the oil has 21 Feb 2019 How do you know what the right viscosity grade is for your vehicle? oil with a high viscosity grade that is not marked 'W', meaning SAE 8, 12, Motor oil provides lubrication to a vehicle's engine, keeping the moving parts from The "W" indicates that the first number is the "cold" or "winter" rating.
17 Sep 2019 In this case, the 10W (w – winter) means that the oil has a maximum viscosity rating of 10 in low temperatures, offering protection down to an
The W stands for winter not weight and there is a standard called the SAE Viscosity Grades for Engine Oils – SAE J300. To label multi-viscosity oil 10W-30 or any
