What does the w mean in 10w40 motor oil

5w30 vs 10w40 motor oil. What is the difference between 5w30 and 10w40 motor oil? The difference is in the viscosity of each at different temperatures. The numbers of the oils depicts their respective viscosities at low and high temperatures. The first number shows the oil’s viscosity at low temperatures and the last number shows the oil’s viscosity at high temperatures. The ‘w’ means

31 Jul 2017 The number after the W describes how thick the oil is at the engine's normal Multigrade oils such as SAE 5W-30 and 10W-40 are widely used  Motor oil grades that contain the letter "W" indicate multigrade oil. These products contain a low-viscosity motor oil as well as various polymer additives. The  In 10W/40 motor oil, the W stands for weight, right? Wrong. It stands for Winter. A vehicle's oil has to be thick, but not too thick. It is important that  28 Nov 2018 This means that if the engine is cold, the engine oil should not an engine oil with a viscosity rating of 10W30 and one with 10W40, you will Ideally, you would want to use a 10W30 engine oil if you live in colder climates. Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils In an engine with a recirculating oil pump, this heat is transferred by means of airflow over the exterior surface of the [oil The higher numbers of a gear oil (e.g., 75W-140) do not mean that it has higher viscosity than an engine oil.

"The W means the oil meets specifications for viscosity at 0 F and is therefore suitable for Winter use" But, what are the viscosity specs at 0 F 

What are motor oil viscosity ratings? graphic.jpg. Viscosity is notated with the common "XW-XX." The number preceding the "W" rates  26 Jun 2014 We explain what the various numbers etc really mean.

For starters, in oil nomenclature, “W” does not stand for “Weight”. It stands for The difference between 10W-30 and a 10W-40 is the high temperature viscosity.

In 10W/40 motor oil, the W stands for weight, right? Wrong. It stands for Winter. A vehicle's oil has to be thick, but not too thick. It is important that in the winter, the oil be thin enough to allow for the engine to start. But when the engine is warm, the oil must be thick enough to lubricate properly. That's where the numbers come into play.

13 Nov 2017 We try to answer the commonest question – “Which Engine Oil should you use?”. a lot of confusion among bikers with respect to the different engine oil This article is prepared to make a layman understand what does  Motor oils designed for cars, vans, and light trucks with gasoline engines fall under API's “S” duty trucks and vehicles with diesel engines fall under API's “C” . (Commercial) 0W-20, 0W-30, 5W-20, 5W-30, 10W-30, 10W-40, 20W-50. 0W- 20  14 Feb 2018 This means that the 5w30 oil will protect the engine better at low temperatures Difference between 5w30 and 10w40 Motor Oil to minimize the wear and tear of surfaces that are in contact with each other. These numbers, however, do not depict the actual viscosities of the oils at extreme temperatures. 2 Aug 2019 The average layperson might think that all motor oil is the same. Every oil container has a series of numbers on it with the letter “W” in the then you would want thicker oil in your engine, such as 15W40, 10W40, or 20W50.
