An example is 5W30—the “W” stands for winter and the oil's cold weather rating. The lower the W number, the better the oil will perform in colder temperatures. 2 Jan 2020 5W30, 5W20, 10W-30. What do different motor oil viscocities mean? Which is best for high mileage? Use a 5W30-weight oil in your vehicle in the very cold months, as long as it is approved for use in your vehicle. 5W30 motor oil flows better and won't become as 24 Jan 2019 Motor oil, the 'blood' that keeps your engine lubricated and protects it from wear, still holds the crown as one of the most important, but 22 Jan 2020 Synthetic oil is the best winter motor oil. We're done here. If only it were that simple. But most people want empirical data to support such claims
17 Aug 2018 There are three core types of engine oil on the market: mineral, The SAE tests oils and assigns an arbitrary weight or grade (viscosity) number to the oil viscous oils suitable for low temperatures generally found in winter. 30 Jan 2020 And which motor oil should you use for your car? assigned with the alphabet W , which stands for “winter”, or low temperatures, not “weight”. 23 Aug 2011 A detailed explanation on how to decipher the labels on motor oils. often recommended one oil for the summer and another for the winter. This is the viscosity of the oil, not the weight or grade as labeled on the oil can.
AMA's Randy Loyk on how to choose the best motor oil for your vehicle. The 5w refers to the oil's viscosity in winter (“w” stands for winter, not weight), with
22 Apr 2019 For example, vehicles must endure cold weather during winter and hot This happens because the wrong weight of engine oil can do a poor 28 Nov 2018 But, what is the main difference in engine oil viscosity? Find out Oh, by the way, the letter 'W' stands for Winter which is the cold weather so far, you can now easily differentiate a 10W30 engine oil from a 10W40 motor oil. 15 Jun 2018 For most motor oils on the market today, their weight ratings come in the form of two numbers. The first, followed by a “W”, is the winter rating. 15 Jan 2016 “W” means “winter” and the numbers are the low and high temperatures at which the oil can safely protect the engine. 5W30 Motor Oil. Average
The 5w -30 is a thin motor oil , you can use 30w ,that's a good grade oil to use in the winter . If you want to change it for the summer then you could use the 5w -30. Source(s): Knowledge of Viscosity means a fluid's resistance to flow. In motor oil, it's rated at zero degrees Fahrenheit (represented by the number preceding the "W" [for winter]) and at 212 degrees (represented by the second number in the viscosity designation). Motor oil thins as it heats and thickens as it cools. The weight in motor oil describes the viscosity of the oil at certain temperatures. When oil is cold it becomes thick and may not move freely within the engine, and when it is hot it may become too thin to offer protection from friction. The lower the number, the thinner the oil and the more easily it flows. In 10W-40 oil, for example, the two numbers mean that it’s a multi-viscosity oil. The 10W is an index that refers to how the oil flows at low temperatures (in Winter); 40 refers to how it flows at high temperatures. Choose a specialized oil designed for higher mileage use to keep your engine running strong. How Winter Affects Engine Oil. Now that you’ve determined the type of oil, it’s time to find out the best oil weight to achieve optimal viscosity in the winter, which you can do by consulting your owner’s manual or looking it up on our website.
