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.

Functions of Engine Lubrication System: 1.       Lubricate Engine parts to minimize wear. 2.       Lubricate Engine parts to minimize power loss due to friction. 3.       Act as a seal between piston and cylinder wall. 4.       Absorbs shock between bearings and other engine parts. Thus extending engine life reducing noise and breakage of engine parts. 5.       Act as a cooling agent. 6.       Also act as a cleaning agent. Properties of oil: a.       Viscosity. b.       Power point. c.        Resistance to carbon formation. d.       Oil oxidization   resistance. e.       Compression and rust protection. f.         Foaming resistance. g.       Extreme pressure resistance.
