- Typically during a pressure test, the pressure should not drop more than_____ psi between shifts.arrow_forwardList five different types of oil rating systemsarrow_forwardWhich 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_forward
