One of the primary functions required of an oil is to stand up to high loadings and high temperatures, while remaining a good lubricant. Oil, as it emerges from the refinery process, is a slippery liquid, but it lacks additives vital to its intended functions.

These additives turn a liquid into a lubricant that fights heat, cold, contamination, corrosion, rust, wear, and other environmental and mechanical hazards. Lubricant additives are grouped into three general categories according to the functions they perform:

 protect the lubricated surface

 improve lubricant performance

 protect the lubricant

Surface protective additives include anti-wear agents, corrosion and rust inhibitors, and detergents and dispersants. Performance additives include pour point depressants, seal swell agents, and viscosity index improvers. Lubricant protective additives cover anti-foamants, anti-oxidants, and metal deactivators.

Oil Characteristics

There are four important characteristics to be considered in an oil: viscosity, pour point, shear stability, and thermal stability.

Viscosity

All natural lubricants thin as they warm, and thicken as they cool. The magnitude of this change is measured by the Viscosity Index (VI). The higher the VI number, the less effect temperature has on viscosity change. An oil with a VI of 200 is very good in this respect.

Pour Point

The pour point of an oil is a measure of its low temperature suitability. Chemical compounds, called pour point depressants, are used to allow the oil to flow even at low operating temperature when the oil has thickened.

Shear Stability

Oil viscosity can also change due to shear. Actual mechanical shearing of long chain polymers in oil will act to lower both the actual viscosity at any given temperature and the Viscosity Index.
