Understanding Viscosity Ratings

If you have endured a scenario of purchasing motor oil, you may have been exposed to something called viscosity ratings. In case that you were clueless about the meaning of the term, know that you are a part of a large group of people with this issue.

Viscosity is the measurement of how much resistance a particular motor oil has to its flow. In simple terms, it measures how fast the oil will flow once you try to pour it out. Most ratings come in the format that begins with a number accompanied by a W and finished off with another number.

The pre-W number indicates how fast oil movies in cold temperatures. This is important for the winter when the engine must get its lubrication fast. The second number is for oil's flow at high temperatures.
