Major Functions of Lubricating Oils

-Transferring generated heat in engine parts -Absorbing shock of engine parts and bearings -Sealing of piston rings and body of pistons -Transferring soot and external materials; preventing particles from deposition -Preventing from rust and corrosion of internal engine parts -Resistance against oxidation -Neutralization of acids

Major Functions of Lubricating Oils

Engine Oil

-          Transferring generated heat in engine parts

-          Absorbing shock of engine parts and bearings

-          Sealing of piston rings and body of pistons

-          Transferring soot and external materials; preventing particles from deposition

-          Preventing from rust and corrosion of internal engine parts

-          Resistance against oxidation

-          Neutralization of acids

Gas Engine Oils

-          Producing low soot

-          Protection of parts against abrasion

-          Resistance against oxidation

-          Cleansing and suspension power

Gear Oil

-          Resistance against high pressure

-          Supplying boundary lubrications

-          Proper lubrication in a wide temperature range

-          Resistance against oxidation

-          Decline of friction and abrasion

-          Resistance against developing grooves in the oil in low temperatures

-          Easy replacement of gear in low temperature for manual gearbox

Hydraulic Oil

-          Transmitting power from one point to another

-          Lubrication of parts

-          Protection of parts against abrasion and rust

-          Transferring heat out of the system

-          Sealing and supplying pressure

-          Perfect separation of water and air

-          Application in wide temperature range

Rotating Oils

-          High resistance against oxidations

-          Lubrications in wide temperature range

-          Prevention of parts from rust and corrosion

-          Perfect separation from water
