Lubrication Systems Test Questions and Answers Already Passed Identify five roles that engine oil performs in a lubrication system. It provides cooling, cleans components, seals and cushions surfaces, guards against corrosion, and minimizes friction. What term describes an oil's resistance to flowing? Viscosity. What kind of viscosity does oil have if it flows easily? Low. What type of viscosity is characteristic of oil used in reciprocating engines? High. What term refers to the measurement of how much an oil’s viscosity changes with temperature variations? Viscosity index. 2 If an oil’s viscosity remains relatively stable despite temperature changes, it has a _______ viscosity index. High. What is the term for the temperature at which a liquid starts to emit flammable vapors? Flash point. Which SAE rating is equivalent to Aviation 80 engine oil? 40. In what situations is straight mineral oil used in aircraft reciprocating engines? For new or recently overhauled engines and older engines. How do the lubrication qualities of straight mineral oil compare to those of ashless dispersant oil? They are not as effective. 3 What type of viscosity do synthetic lubricating oils generally have? Multi. What steps are required if an incompatible oil is added to a turbine engine? Flush and refill the oil system. Do turbine engine oils follow a standard identification system? No. Are SAE numbers used for identifying turbine
