It's All In The
Formulation
Motor Oils, Drivetrain Lubes and Hydraulic Oils are
formulated to carry out specific tasks
Motor Oils
In the early days of automotive
lubrication, motor oil was just plain base oil. When wax modifier was
added to the base oil in the 1920s to address the problems created by
wax residue, the motor oil additive market was born. Today, motor oils
contain a wide variety of additives designed to improve their protection
and performance capabilities. Motor oil additives serve three essential
functions: protecting metal surfaces, expanding the lubricant's
application range and extending the lubricant's life.
Surface Protection Additives
Surface protection additives effectively
address issues related to metal surfaces:
-
Anti-wear agents protect against
friction, wear, scoring and seizure.
-
Corrosion and rust inhibitors protect
internal metal parts against corrosion and rust.
-
Detergents keep surfaces free of
deposits
-
Dispersants prevent insoluble
contaminants from agglomerating (clustering or massing) by keeping
them dispersed in the lubricant.
-
Friction modifiers alter the oil's
coefficient of friction.
Performance Additives
A second group of additives serves to
improve the lubricant's performance:
-
Pour point depressants (used in
petroleum lubricants) modify wax crystal formulation and enable oils
to flow at lower temperatures.
-
Seal swell agents help swell
elastomeric seals by causing a chemical reaction in the elastomer.
-
Viscosity modifiers help reduce the
rate of viscosity change when the temperatures rise or drop.
Protective Additives
A third group of additives works to
extend the service life of the lubricant:
-
Anti-foamants reduce surface tension
and speed the collapse of foam.
-
Anti-oxidants reduce the oxidation
rate by decomposing peroxides and terminating free-radical
reactions.
-
Metal deactivators reduce the
catalytic effects of metals on the oxidation rate, further slowing
oxidation.

exceed the high performance demands of modern engines, effectively
withstanding the stress of higher horsepower, higher heat and
complicated emission control systems. AMSOIL synthetic motor oils
consistently outperform competitive conventional and synthetic motor
oils for superior protection and performance over extended drain
intervals.
Drivetrain Lubricants
Although gear oil faces many of the same
challenges as motor oil, it also has additional responsibilities, such
as carrying damaging wear debris away from the contact zones and
muffling the sound of gear operation. Gear oils are placed under extreme
levels of pressure, often leading to boundary lubrication conditions
(when a full fluid film does not exist between surfaces). Differentials
in cars and trucks feature a ring-and-pinion hypoid gear set that can
experience boundary lubrication, pressures and sliding action that can
wipe most of the lubricant off the gears. Extreme-pressure (EP)
additives are added to gear oil in order to provide additional
protection within this extreme environment.
Additional Challenges
Additional challenges faces by gear oils
include rust and corrosion protection. Because many of the components
found in the drivetrain consist of ferrous material, drivetrains are
more susceptible to rust and corrosion than engines.
Gear sets found in the drivetrain can be
noisy and may be subject to shock-loading conditions. The viscosity and
extreme-pressure formulation of gear oil quiets gears and dissipates
shock loading.
The rotating motion of gear sets chums
the gear lube, subjecting it to foaming and significantly reduced
load-carrying capacity. When gear teeth come into contact with each
other, trapped air bubbles compress and reduce the thickness of the
separating oil film, leading to direct metal-to-metal contact and
increased wear levels. Only the air is compressible; the oil is not. The
gear oil must have the ability to dissipate this entrapped air, ensuring
a sufficient lubricating film exists to protect the gears from contact
wear.
Drivetrain Fluid Additives
Like motor oil additives, drivetrain
fluid additives improve the protection and performance capabilities of
the base oil. Many of the challenges faced by the drivetrain fluids are
met by the additives.
-
Extreme-pressure and anti-wear agents
minimize component wear in the boundary lubrication situations.
-
Pour point depressants improve
low-temperature performance.
-
Rust and corrosion inhibitors protect
internal components.
-
Oxidation inhibitors reduce the
deteriorating effects of heat, increasing the lubricant's service
life.
-
Viscosity index improvers allow the
lubricant to operate over a broader temperature range.
-
Anti-foam agents reduce the harmful
effects of air trapped in a lubricant.
-
Friction modifiers reduce friction.
AMSOIL Severe Gear®
Synthetic Extreme Pressure (EP) Gear Lubes
are specifically engineered for maximum performance in the severe-duty
applications. Featuring an exclusive blend of high viscosity,
shear-stable synthetic base oils and an extra treatment of
high-performance additives. Severe gear maintains its viscosity for
long-lasting protection against metal-to-metal contact. The proprietary
AMSOIL additives form an iron-sulfide barrier coating on gear surfaces,
providing the ultimate line of defense against wear, pitting and
scoring.
AMSOIL Synthetic Universal Automatic Transmission Fluid (ATF)
is engineered to exceed the performance requirements of domestic and
foreign automatic transmission fluids, offering smooth shifting, long
transmission life and excellent lubricating protection and performance
in temperature extremes.
AMSOIL Synthetic Fuel Efficient Automatic
Transmission Fluid (ATL) is engineered to exceed the
requiements of GM, Ford and Toyota where low-viscosity oil is required,
providing outstanding protection and performance over extended drain
intervals, even in severe operating conditions.
Hydraulic Fluids
Hydraulic oil not only
provides the medium for hydraulic power, it is also responsible for
lubricating hydraulic components, cooling the system by transferring
heat and minimizing wear, friction, deposits, rust and corrosion.
Standard Hydraulic fluids
are composed of about 99 percent base oil and 1 percent additives.
Although water was used as the original hydraulic fluid, it was replaced
by mineral oil base stocks in the 1920s due to their lubricating
properties and higher boiling points. Modern hydraulic fluids are
composed of either mineral, synthetic or natural (vegetable) oil base
stocks, as well a wide range of additives such as antioxidants,
anti-wear agents, demulsifiers, detergents, dispersants, foam
inhibitors, pour point depressants, metal deactivators, rust inhibitors
and viscosity modifiers. A variety of different additive packages are
used in different hydraulic fluids, and selecting the right package is
critical to equipment performance and life.
AMSOIL Synthetic Anti-Wear Hydraulic Oils
(AWF,AWG,AWH,AWI,AWJ) are shear-stable, long-life lubricants formulated
with premium synthetic base oils and additive systems that inhibit
oxidation, rust and foam. Synthetic Anti-Wear Hydraulic Oils also
contain a very effective zinc-based anti-wear/antioxidant additive that
prevents wear in high-speed, high-pressure vane and gear pumps while
meeting the lubrication requirements of axial piston pumps with
bronze-on-steel metallurgy. Synthetic Anti-wear Hydraulic Oils reduce
maintenance cost by extending drain intervals and reducing labor
associated with repairs, downtime and change outs.
AMSOIL Synthetic
Biodegradable Hydraulic Oil (BHO) is designed to biodegrade to its
natural state when subjected to sunlight, water and microbial activity.
Because it is formulated with ashless additives that do not contain
heavy metals, it has a very low toxicity level. BHO is based on
high-quality, Synthetic oil chemistry that outperforms vegetable
oil-type, biodegradable hydraulic oils.
