Can oil and gear oil mix?

Oil and gear oil are quite different, the two can not be mixed.

Main functions of oil: lubrication, cleaning and dispersing, cooling and sealing
Lubrication is actually the easiest to be guaranteed, because even the most common lubricating oil has good lubrication performance. A CA6140 lathe in the factory in the 1970s has been used for nearly 50 years. The gears are in good condition and the ordinary lubricating oil has been added all the time.
Engine combustion products need oil to dissolve and clean. Otherwise, these impurities will gradually harden at high temperatures, which will affect the normal operation of the engine.
An oil seal is also required between the piston ring and the cylinder wall to prevent gas channeling.

Cooling, the cylinder has been burning fiercely, the temperature is very high, the cylinder wall and cylinder head has a cooling channel, can be cooled through the coolant, and the piston because of its particularity can not be directly cooled by the coolant, so the engine piston will have an oil injection port below the piston to the bottom of the piston to cool the piston.

Therefore, due to the particularity of the engine work, the oil requirements are more.

Gear oil is mainly anti-wear and lubrication
Gear oil is used in differential and gearbox, these places are mainly gear meshing to transfer power, and are located at the end of the transmission system, need to slow down and increase torsion, so the gear transmission load is very large, need more viscous oil to ensure that the contact surface in the strong bite there is still the existence of lubricating oil.

The viscosity of gear oil is very high, which ensures that the oil film on the contact surface is not destroyed under large load. And some vehicles also add graphite in the gear oil, we use the main component of pencil lead is graphite, graphite is also a kind of lubricant, added to the gear oil can increase the wear resistance. In order to increase the anti-wear gear oil is often added with other substances, so the gear oil smells mostly pungent.

Gear oil and engine oil performance and function are completely different, so can not be mixed. But usually use gear oil to lubricate the chain is better than oil.
