Motor Oil Viscosity Explained

Engine oils are manufactured in different viscosity levels. Viscosity describes the fluid thickness and the amount of resistance the oil withstands. For example, water has a low viscosity and honey has a greater viscosity. The numbers on an oil container indicate the reading. A 10W-30 oil has a viscosity of 10W when the engine is cold and a viscosity of 30 when the engine is running, as cold oil is generally thicker.

Oils having lower viscosity are preferred at colder temperatures. Thinner or less viscous oils better lubricate engines in cold climates. On the other hand, thicker or more viscous oils are better in warmer climates as the substances typically thin with heat. Some engines do not require much of a viscosity difference when hot or cold. In this case, the oil label may only indicate one reading.

Bring your vehicle for an oil change at the Lee Hyundai of Goldsboro garage to have the proper oil installed.
