The suffixes (0, 5, 10, 15 and 25) followed by the letter W designate the engine oil's "winter" grade. Look to your owner's manual. It specifies the viscosity grade required for your car's engine. Today, the most common grades are 5W-30 and 10W-30.

11 Apr 2018 Here in this article, we will explain to you all the basics of engine oil, oil which complies with the grade recommended by the manufacturer  Viscosity Explained. Browse all locations. You hear the word all the time when you are getting your oil changed, but exactly what is viscosity? It's what the  Oil Specifications Cheat Sheets for Organizations and for OEMs are Now Available! VW 507.00, VW 504.00, etc: Volkswagen Motor Oil Specifications Explained New Gear Oil Viscosity Grades: SAE 65, 70 and 75 · Introducing the SAE 8  17 Nov 2016 Viscosity and specification explained. Engine Engine oils are 'multi-grade' to cope with a wide range of operating temperatures. Additives  18 Aug 2014 Multi grade oils are clever in that they act like both a cold and hot oil rather than being ideal for one or the other. At start up, multi grade oils can  8 Sep 2017 Here at Gerrard Hydraulics, we stock and sell two grades of hydraulic oil, 46 and 68. But what do these numbers actually mean and how do you 

18 Apr 2015 If you put a heavier weight oil in the engine than what is called for, your As for what do the numbers mean this post should explain it all.

The second number after the "W" indicates the oil's viscosity measured at 212 degrees Fahrenheit (100 degrees Celsius). This number represents the oil's resistance to thinning at high temperatures. For example, 10W-30 oil will thin out at higher temperatures faster than 10W-40 will. The SAE grading system indicates oil viscosity in simple numbers ranging from the thin oil (10) to the very thick oil (140 or above). Heavier weight, or higher grade oil is more viscous and therefore thicker as it flows between the gears. Light grade oil is ideal for small, fast, polished gears under a light load. Most of the time when viscosity is explained words are used that are too technical for the average person to quickly grasp. 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. It depends. Some vehicle manufacturers provide a range of recommended motor oil viscosity grades based on the outside temperature in which the car is driven. Other manufacturers recommend the use of only one motor oil viscosity grade. The idea is to cause the multi-grade oil to have the viscosity of the base grade when cold and the viscosity of the second grade when hot. This enables one type of oil to be used all year. In fact, when multi-grades were initially developed, they were frequently described as all-season oil. The viscosity of a multi-grade oil still varies logarithmically with temperature, but the slope representing the change is lessened.

Deciphering the Oil Grade. The starting number of both the oils is the same which is '10'. This indicates how easy it is  Viscosity, in simple terms is the thickness of the oil. The higher the number, the thicker the oil is, which also indicates that the oil is resistant to flow. What are engine oil grades? Engine oils have got different grades which are differentiated on the basis of their viscosities. Viscosity is the quantity expressing the internal friction of the fluid. 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. The second number after the "W" indicates the oil's viscosity measured at 212 degrees Fahrenheit (100 degrees Celsius). This number represents the oil's resistance to thinning at high temperatures. For example, 10W-30 oil will thin out at higher temperatures faster than 10W-40 will. The SAE grading system indicates oil viscosity in simple numbers ranging from the thin oil (10) to the very thick oil (140 or above). Heavier weight, or higher grade oil is more viscous and therefore thicker as it flows between the gears. Light grade oil is ideal for small, fast, polished gears under a light load.
