What Are Synthetic Lubricants?
Engines, Transmissions and other mechanical systems contain hundreds of moving parts.
Though the metal surfaces of these parts look smooth, they are actually full of microscopic peaks
and valleys. When the peak of one surface touches its mating surface, it causes damage.
Damage may lead to component failure or wear. Failure prevention and wear reduction are the
primary functions of lubrication.
REFINED OILS
Conventional oils-the oils most people are familiar with- are refined from crude oil. Refining is a
process of physically separating light oil components from heavy ones.
Crude oil contains millions of different kinds of molecules. Many are similar in weight but not in
structure. The refining process cannot distinguish from molecules, so a wide assortment of
molecules is present in the finished lubricant made from crude oil stocks.
Some crude oil molecules are not beneficial to the lubrication process. For example, paraffin
causes refined lubricants to thicken and flow poorly in cold temperatures. Molecules containing
sulfur, nitrogen and other elements invite the formation of sludge and other products of lubricant
breakdown, especially in high-temperature applications. Sludge and breakdown products
significantly increases wear rates.
The assorted molecules of refined lubricants also have different shapes, making lubricant surfaces
irregular at the molecular level. As lubricant layers flow

The main advantage of mineral oils is their low cost. The
main limitation of mineral oils is that… the lubricant-sized
molecules have a variety of structures ranging from the best
to the worst (in terms of wear control).

across one another during the lubrication process, these irregularities create friction, which
consumes power, reduces efficiency and increases heat and wear.
SYNTHETIC LUBRICANTS
Synthetic lubricants are chemically engineered from pure chemicals rather than refined from
crude oil. That gives them significant advantages over refined oils.
PURE- The feedstocks from which synthetic lubricants are made do not contain sulfur, nitrogen
or other elements that invite the formation of sludge and other products of lubricant breakdown.
Synthetic lubricants can be used in higher temperatures than refined lubricants without
breakdown. Their resistance to breakdown also allows them to be used longer than refined
lubricants can be used. Lubricated systems stay cleaner and last longer with synthetic lubricants.
______________________________________________________________
Synthetic lubricants differ from refined oils in three
key ways: synthetics are pure, their molecular structure is
uniform, and they may be designed to work in applications
in which refined oils cannot.
______________________________________________________________
UNIFORM – The feedstocks from which synthetic lubricants are made feature uniform and
smooth molecular structures, which ensures low friction as lubricant layers slide across one
another. Reduced friction increases energy through-put for greater fuel efficiency and power and
reduces heat and wear for longer equipment life.
Molecular uniformity also helps synthetics resist thinning in heat and thickening in cold, which
helps them protect better than refined oils over a system’s operating temperature range and
helps ensure secure sealing.
_________________________________________________________
Field experience has shown that synthetics can give
economic benefits when used in place of mineral oils,
which were working satisfactorily. The benefits fall in
five general areas:
1) Improved energy efficiency
2) Wider operating temperatures range
3) Increased design ratings
4) Reduced maintenance
5) Better reliability and safer operation

DESIGNABLE
Many different kinds of feedstocks may be used to create synthetic lubricants, allowing a synthetic
to be designed for virtually any application. Some feedstocks are ideal for use in extremely cold
environments. Others are perfect for use in extreme heat. Some are extremely safe in
applications in which refined lubricants pose a fire or explosion hazard. Refined oils simply do
not offer the design flexibility synthetics offer.
The design flexibility of synthetics also allows them to be tailored very specifically to the needs of
everyday applications, such as automotive engines, commercial equipment or much industrial
machinery. That specificity helps ensure long life and peak power, performance and fuel
economy from the lubricated system and long lubricant life.
