7 responsibilities of a motor oil

1 Minimize Friction and Wear

The #1 function of a lubricant. Friction is detrimental to engine
components and results in wear, so a lubricant must act as the barrier
between moving parts.

2 Cleanlinessimage

Internal cleanliness of an engine depends on contaminants being
suspended, preventing them from adhering to engine components.

3 Cool Moving Parts

Engines rely on lubricants to help them run cooler by absorbing heat
and moving it to a different location to be safely dissipated. The cooler
the operating temps, the better your engine can perform.

4 Prevent Contamination by Acting as a Seal

Acting as a seal, motor oils help minimize combustion by-products from
contaminating the lubrication system. Lubricants act as a dynamic seal in
locations such as the piston, piston ring and cylinder contact areas.

5 Dampen Shock

In the event of mechanical shock, lubricants help cushion the blow.
The lubricant fi lm can absorb and disperse energy spikes over a broader
contact area, reducing impact.

6 Prevent Corrosion

Corrosion of internal components can be reduced or prevented by
lubricants, by either chemically neutralizing corrosive products or setting
up a barrier between the components and the corrosive material.

7 Transfer Energy

At times a lubricant is required to act as an energy-transfer medium,
such as in the case of hydraulic equipment or valve lifters in an
automotive engine.
