AMSOIL Synthetic Lubricants
Excel In Temperature Extremes
Better Known for Their Cold-Temperature Benefits, Synthetics
Are Equally Beneficial in Extreme Heat.
Vice President, Technical Development
Summer is on its
way, and thank goodness; this winter has really been hard
on everything! Wildlife, water mains, heating budgets, people
- and our vehicles - have all suffered through this winter.
As of Februaty 11, 2014, Duluth, Minnesota. marked 23 consecutive
days with a low temperature below zero. The last day a low
temperature was zero or above was January. 19, with a low
of 13 degrees Fahrenheit.
We often think
about synthetics' low-temperature properties - maintaining
flow in sub-zero conditons to lubricate vital components and
ensure startups on the coldest mornings - but with a hint
of spring on the horizon it's time to get ready for summer.
One of the many benefits of synthetic motor oils is their
excellent all-weather performance. What happens to lubricants
during the dog days of summer in the desert Southwest where
daytime temperatures routinely climb above 100 degrees Fahrenheit?
Driving a vehicle under these conditions stresses lubricants
also, but in different ways than driving in subzero temperatures.
conditions subject oils to stress that can result in sludge
and varnish formation in your engine and transmission, resulting
in major damage. There are a bunch of tests that can be run
on used oil to help predict sludge and varnish formation,
including oxidation, nitro-oxidation, viscosity increase and
total base number (TBN) depletion. If you are not interested
in becoming a used-oil analysis expert, make sure to pick
lubricants proven to withstand the heat. One of the main differentiators
of lubricants is how long they can effectively fight sludge
and varnish formation. In the southern half of the United
States, the chemical reactions that create sludge and varnish
are accelerated with high temperatures. As a general rule,
chemical reaction rates, including sludge and varnish formation,
double with every 10 degrees Celsius (18 degrees Fahrenheit)
rise in temperature. So if you live in Phoenix, Arizona, your
vehicle lubricants better be designed to hold up to these
accelerated reaction rates. It takes detailed knowledge of
lubricant chemistry and field experience to get it right.
effectively separated to reduce friction is another concern
down in Phoenix, Arizona, during the summer. Reducing friction
will reduce the amount of heat that is generated, which will
lower the operating temperature of the component. Anti-wear
components help maintain this separation of surfaces, but
lubricant thickness is the main mechanism.
When oil gets too
thin, friction and heat are generated. Since lubricants generally
thin as temperatures go up, they need to be designed to provide
effective separation at the highest expected operating temperature.
An oil's base stock and formulation influence this property,
called viscosity index (VI), which indicates the change in
oil viscosity in relation to temperature. Oils with high viscosity
indices have smaller changes in viscosity due to temperature
changes than do oils with low viscosity indices; therefore,
it is desirable for oils to have higher viscosity indices.
As you might expect, synthetic motor oils have higher viscosity
indices than conventional mineral-based oils do.
We also rely on
engine oil to absorb heat from the contact surface area and
transport it to a location where it can be safely dissipated
(an oil cooler or sump). As oils age, they cannot carry away
as much heat, so temperatures increase, accelerating the chemical
reactions which result in sludge and varnish.
Hot summer temperatures
were part of the challenge facing AMSOIL Signature Series
Synthetic Motor Oil and Signature Series Multi-Vehicle Synthetic
Automatic Transmission Fluid during the 2011-12 Las Vegas
Taxi Cab Field Study. Over the course of 18 months, test vehicles
operated in the fleet's service area of Las Vegas up to 24
consecutive hours daily, accumulating more than 7,000 hours
of service. Like most taxi cabs, the vehicles operated in
stop-and-go conditions where excessive idling is the norm,
but they also faced the grueling summer temps of Vegas where
daytime highs often exceed 100 degrees Fahrenheit. Hour after
hour, day after day, under such punishing conditions, AMSOIL
lubricants proved up to the task. Engine and transmission
components from the test vehicles were later examined and
found to have minimal or no notable wear, even after practicing
extended drain intervals.
Few of us operate
our vehicles under such severe settings, but it is reassuring
to know that AMSOIL synthetic motor oils provide outstanding
wear protection and superior high-temperature performance
in the harshest conditions. The next time you're driving during
one of those summer scorchers or battling stop-and-go traffic,
be assured that AMSOIL synthetic motor oil is working hard
under the hood to keep your engine running cool. Published,

AMSOIL Signature Series
Synthetic Motor Oil
AMSOIL Signature Series Synthetic
Motor Oils are formulated to meet the latest API SN Resource
Conserving and ILSAC GF-5 industry specifications. AMSOIL
Signature Series Oils include 0W-20, 0W-30, 5W-30 and 10W-30
and represent the very best motor oils AMSOIL has to offer,
allowing motorists to take advantage of maximum extended
drain intervals. AMSOIL Signature Series Synthetic Motor
Oils are recommended for drain intervals of up to 25,000
miles/one year, whichever comes first (15,000 miles/one
year in severe service conditions).

Synthetic Motor Oils offer the longest drain intervals
on the market, unsurpassed protection and performance that
effectively extends equipment life and improved fuel economy,
saving customers money at the pump and reducing the nation's
dependence on foreign oil.

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
