What do Motor Oil Viscosity Ratings Mean?

You may have heard that motor oil helps keep the engine lubricated and prevents metal components from clashing with each other. What you may not fully comprehend, however, are the seemingly complicated viscosity ratings.

What viscosity showcases is how fast your motor oil flows. A low viscosity means oil is thick and moves slower, while a high viscosity indicates a thin and fast-moving oil. This is important, as oil must move differently during summer/winter when the outside temperatures in Arlington, VA are reaching the extreme ends of the spectrum.

Consider, for example, a 5W-30 viscosity. The first part, 5W, is viscosity at low temperatures. The second number, however, is viscosity at 100 degrees Celsius. If you are one of the many people still confused by this concept, feel free to visit us at at our auto service shop. Not only will viscosity ratings become effortless to understand, but we will also help match you with the right motor oil.
