Oil that flows freely has a ____ viscosity.
Low.
The oil used in reciprocating engines has a relatively _____ (high or low) viscosity.
High.
The measure of the change in viscosity with a given change in temperature is know as
the ______ ________.
Viscosity index.
An engine lubricating oil whose viscosity changes very little for a given change in
temperature has a _______ viscosity index.
High.
The point at which liquid will begin to give off ignitable vapors is known as the _______
point.
Flash.
Aviation 80 engine oil has the same viscosity as SAE ____
40
The use of straight mineral oil in aircraft reciprocating engines is associated with what
conditions?
New/newly overhauled engines and older engines.
The lubricating properties of straight mineral oil _______ (are/are not) as good as those
of ashless dispersant oil.
Are not.
Synthetic lubricating oils are ______ (multi or single) viscosity oils.
Multi
If incompatible oil has been added to a turbine engine, it is often necessary to _____
and ______ the oil system before refilling with the proper oil.

Turbine engine oils ______ (do or do not) use a standard identification system.
Do not.
SAE numbers _____ (are or are not) used to identify turbine oils.
Are not.
Two types of lubricating systems for reciprocating aircraft engines are _________ and
___________.
Wet sump and dry sump.
The lubricating is distributed to the parts of a reciprocating engine by these three
methods:
Pressure, Splash, and combination (spray).
The main disadvantages of a wet-sump engine are:
Size is limited, cooling is less efficient, and temperature is higher.
What two markings must be on the oil filler cap?
Oil, and the tank capacity.
