High Quality Oil Is Necessary
To Keep Cold Weather Hydraulic Applications Operational
grade is not the only indicator of performance.
Technicle Product Manager, Drivetrain
Most of us have
watched one of the popular reality-TV shows involving fishing,
mining, logging or trucking. Without fail, there seems to
be some dramatic mechanical failure that keeps us in suspense
during the commercial break. Failures involving hydraulic
systems often happen in cold temperatures. Many of us can
sympathize with the guy on the show; he's shown lying under
the equipment with no gloves on his hands, snow is falling
and his jacket is covered in oil. The drama provides great
entertainment, but also a great example of the significant
time and money lost every year in hydraulic equipment operated
in cold temperatures.
So why do these
guys always end up facing hydraulic equipment failures in
the middle of the winter? Most often it is due to poor maintenance,
poor startup procedures and continued use of a cheap hydraulic
fluid that gets too thick in cold temperatures.
hydraulic system maintenance throughout the year can significantly
reduce cold-temperature downtime. Unfortunately, tight schedules,
remote job sites and the need to keep equipment running at
all costs can mean that badly worn hoses, leaky seals and
other maintenance items go unchanged for extended periods.
The colder the ambient temperature gets the more likely a
catastrophic failure of one of these weak points will occur,
and poor-quality hydraulic oil may accelerate the failure.
Hydraulic oil must
protect moving parts from excessive wear, keep the system
clean and free from varnish and transmit energy to complete
a number of different jobs such as moving mountains of dirt
and cutting trees off at their bases. To do these jobs, it's
critical that the hydraulic oil stay within range for thickness
regardless of the outside temperature. This is especially
important during cold-temperature starts, when damage and
accelerated wear can occur quickly if the oil gets too thick.
Damage and wear
can be caused by starving the inlet side of the hydraulic
pump (pump cavitation). This can occur during cold weather
when oil becomes so thick that the pump is unable to pull
fluid from the reservoir fast enough for continuous lubrication
supply. Instead, the pump pulls air, components become starved
of lubricant and metal-to-metal contact occurs. Overly thick
oil also contributes to pressure spikes that blow hoses, filters
and other critical components. To help prevent this condition,
most equipment manufacturers include hydraulic oil viscosity recommendations in their operator
manuals and will often recommend thinner oil for cold ambient temperatures.
This is one way to help solve the problem, but we all know
that synthetic lubricants provide a solution through higher
viscosity index. High-viscosity-index synthetic hydraulic
fluids remain much more fluid in cold temperatures while maintaining
a protective layer of fluid in high temperatures. The higher the VI, the less the fluid's viscosity
will change due to temperature fluctuations.
of this can be illustrated by comparing a cheap mineral oil
with a high-VI synthetic hydraulic oil. Both oils have the same
thickness of 32 cSt at 40°C (ISO 32). But, the synthetic
hydraulic oil has a VI of 160 and the mineral-oil-based hydraulic
fluid has a VI of 90. When both oils are cooled to 10°F, the low-VI
mineral oil thickens much more than the high-VI synthetic
oil. Even though the oils are classified as having the same
ISO viscosity, the high-VI synthetic oil will flow much better at 10°F. This
means better lubrication for the pump and less chance of a
pressure spike, damaging cavitation or blowing
neglected weak points in the system. Bottom line: Fluids with
a higher viscosity index provide better protection in cold
temperatures than fluids with a lower viscosity index.
On the other end
of the spectrum, hydraulic oils need to fight varnish and
sludge buildup most often associated with high-temperature,
high-pressure industrial environments. Not all hydraulic oils
are designed to provide effective resistance to varnish and
sludge in these environments, and varnish and sludge are directly
responsible for sticking valves and other operational issues.
As temperatures increase, hydraulic oils thin out. In excessive
temperatures, some do not provide the required oil thickness to adequately protect
against wear. Additionally, oils not formulated correctly
for these extreme applications allow varnish to form after
continual operation at high temperatures, and sensitive operationally
controlled valves begin to malfunction.
Just like motor
oils, not all hydraulic oils are created equal, and that is
especially evident in cold-temperature applications. AMSOIL
synthetic hydraulic oils can greatly reduce cold-weather problems.
They also provide outstanding oxidation resistance for longer
fluid life and significantly better resistance to harmful
varnish that plagues many hydraulic systems operating in hot
industrial environments. AMSOIL has the hydraulic products
to keep customers running smoothly in both extreme cold and
in hot industrial environments. Published, AMSOIL Magazine

synthetic motor oils are formulated to surpass engine test
specifications, offering protection far greater than competing
motor oils for extended drain intervals. Most synthetic oil
manufacturers make no claim to extended drain intervals, deferring
to the maintenance schedule provided by the vehicle manufacturer.
With its unparalleled oil and warranty program, AMSOIL offers
consumers unprecedented protection and economics.
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.
NOACK Volatility Test
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
