Understanding the Numbers: What an Oil Viscosity Rating Means

If you are like more than a few motorists, when you seek to have an oil change, you hear or read a set of numbers and letters associated with a particular type of oil. Typically, these sets of numbers and letters are 10W-30 and 10W-40. Although you hear and read them when you seek an oil change, you really may not fully understand what they represent. These different sets of numbers and letters, you may not really know what they represent.

These are the viscosity ratings for different types of oil. The higher the number, the thicker and more flow a type of oil can resist. Oil with a higher viscosity tends to be better for warmer climates or times of the year, oil with lower viscosity for cooler situations.
