What are the properties of lubricating oil? Properties of fuel lubricating oil : i.                     Proper viscosity ii.                  To thick iii.                Viscosity index iv.                Viscosity number. v.                   Multiple viscosity oil vi.                Resistance to carbon formation and oil oxidation. vii.              Corrosion and rust inhibitors. viii.           Forming resistance. ix.                Extreme pressure resistance. x.                   Energy conserving oil.

What are the purposes of engine lubrication system? Lubricating oil is a substance which oil makes possible minimum wear or low friction loss  between adjacent moving surfaces.  The lubricating oil must have  i.                     Lubricate moving parts to minimize wear.  ii.                  To minimize power loss from friction of lubricate moving parts.  iii.                By acting as a cooling agent lubricating oil remove heat from engine. iv.                Lubricating oil reduce engine noise and extending engine life by absorbing shocks between bearings and others engine parts. v.                   Work as a cooling agent. vi.                From a good seal between piston rings and cylinder walls.
