If there is bucket full of oil and bucket full of water and you are asked to lift them, which one of the two will require more effort given that volume of buckets remains same?

Fluids are materials that easily succumb to shearing forces.

Some properties of fluids include:

Viscosity: The property of a fluid that resists the movement of one layer of fluid over another. Viscosity can make basic equations more difficult and can cause turbulence.
Surface tension: The property of a fluid that makes its surface behave like a stretched elastic membrane. This property comes from the cohesive forces between the fluid molecules at the surface.
Specific weight: The weight of a unit volume of a fluid. Specific weight is dependent on acceleration due to gravity.
Compressibility: A type of fluid whose density changes with the application of external force. Examples include gases and vapors.
Incompressibility: A fluid's density does not vary with the application of force. An example of an incompressible fluid is a stream of water flowing at high speed from a garden hose pipe. 

Other properties of fluids include:
Pressure
Density
Temperature
Flow velocity
Speed of sound
