Advantages of Synthetic Base Oils
Noria Corporation
Tags: synthetic lubricants
Petroleum-based mineral oils function very well
as lubricants in probably 90 percent of
industrial applications. They are cost-effective
and provide a reasonable service life if used
properly but have some limitations, depending
upon the specific type of base stock used, the
refining technology, the type and level of
additives blended, and the operating conditions
encountered. The main service difficulties
within mineral oils are:
1. The presence of waxes, which can result in
poor flow properties at low temperature.
2. Poor oxidation stability at continuously high
temperatures, which can lead to sludge and
acid buildup.
3. The significant change in viscosity as the temperature changes, which can cause the
base oil to thin excessively at high temperature.
4. A practical maximum high-temperature application limit of about 125 degrees C (250
degrees F) above which the base oil oxidizes very rapidly. It is desired to keep mineral
oil-based lubricants within the operating range of 40 to 65 degrees C (100 to 150 degrees
F).
Synthetic base oils are expensive because of the processing involved in creating these pure
chemical base oils. Their use must justify the additional cost. There should be a financial
benefit to using them.
With regard to their chemical purity, think of the analogy of a container of balls. Mineral oil
would be like having the container filled with many different balls of different shapes and sizes,
such as footballs, baseballs, tennis balls, ping-pong balls, soccer balls, golf balls, etc. Mineral
oils contain thousands, if not millions, of different chemical structures (molecules). A synthetic
oil would be the equivalent of having the container filled with just one type of ball (tennis
balls). Every structure in the container of synthetic oil is almost identical to the structure beside
it.
The two main advantages of synthetic oils are their ability to outperform mineral oils at high
operating temperatures (above 185 degrees F) and at low operating temperatures (below 0
degrees F). There are other potential advantages, too.
Depending on the type of synthetic, other advantages of synthetic lubricants (beyond the high-
and low-temperature advantage) may include:
Improved energy efficiency (less than 1 percent) due to better low-temperature
properties
Higher oil film strength with some synthetics
Extended warranties by some equipment manufacturers
Lower engine hydrocarbon emissions
Extended drain intervals in some (clean) applications
Biodegradability with some synthetics (esters)
Natural detergency
Higher viscosity index
Fire resistance (phosphate esters)
