Chapter 8, Problem 20RQ
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.

- Which of the following statements about an oils viscosity is not true? 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. In the API system of oil viscosity classification, the lighter oils receive a higher number. Heavyweight oils are best suited for use in high- temperature regions. Low-weight oils work best in low temperature operations.arrow_forwardWhen conducting an oil pressure test: Technician A says that lower than normal pressure can be caused by faulty piston oil rings. Technician B says that lower than normal oil pressure can be caused by excessive engine bearing clearances. Who is correct? Technician A Both A and B Technician B Neither A nor Barrow_forwardWhile looking at the results of an oil pressure test: Technician A says that higher than normal readings can be caused by using oil that is too thin. Technician B says that higher than normal readings can be expected on a cold engine. Who is correct? Technician A Technician Both A and B Neither A nor Barrow_forward
