Textbook Question
Chapter 8, Problem 4TF
True or False? An oil with the classification of 5W-30 has the viscosity of both a 5- and 30-weight oil. The 5W means the oil has a viscosity of 5 when warm and a 30 rating when it is cold.

The ability of oil to resist flow is its viscosity. Viscosity is affected by temperature; hot oil flows faster than cold oiL Oil flow is important to the life of an engine.
