Motor
oils, drivetrain lubes and hydraulic oils are formulated to
carry out specific tasks.
Motor Oil
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 1930s to
address the problems created by wax residue, the motor 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 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 formation
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 temperatures
rise or drop.
Protective Additives
A third group of additives work 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 effect of metals on the
oxidation rate, further slowing oxidation.
Combining the industry's premier
synthetic technology with AMSOIL premium additives, AMSOIL
Synthetic Motor Oils 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 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
faced 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 subjected 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 churns 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 drivetrain fluids are met by the additives:
Extreme-pressure
and anti-wear agents minimize component wear in 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.

(ATL) is engineered to exceed the requirements 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
Fluid
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 as 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. AMSOIL 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. AMSOIL
Synthetic Anti-Wear Hydraulic Oils reduce maintenance costs
by extending drain intervals and reducing labor associated
with repairs, downtime and change outs.

Another
AMSOIL First
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
THE
NOACK Volatility Test
The NOACK
Volatility Test determines the evaporation loss
of lubricants in high temperature service. The more
motor oils vaporize, the thicker and heavier they become,
contributing to poor circulation, reduced fuel economy
and increased oil consumption, wear and emissions. AMSOIL
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
and emissions.
