Many motorcycle
engines share a common lubricant sump with the transmission,
requiring the same oil to lubricate both assemblies. Because
engines and transmissions place different demands on lubricants,
an oil that provides good engine protection may fail to provide
adequate transmission protection. High sliding pressures,
shock loading and shearing forces applied by motorcycle transmission
gears place a great deal of stress on a lubricant, and it
is up to the oil's viscosity and chemical additives to protect
the gears against wear.
The ASTM D-5182
FZG Gear Wear Test is used to determine a lubricant's gear
oil performance. Two hardened steel spur gears are partially
immersed in the test lubricant, while temperature is maintained
at a constant 194 degrees F and a predetermined load is placed
on the pinion gear. The gears are rotated at 1,450 RPM for
21,700 revolutions before being inspected for scuffing. If
the total width of wear on the pinion gear teeth exceeds 20
mm, the test is terminated. If the total width of wear is
below 20 mm, additional load is placed on the pinion gear
and the test continues for another 21,700 revolutions. Each
time an oil passes, it advances to a higher test stage. The
highest stage is 13, and results are reported as the highest
stage passed by the oil. Wear is indicated for the stage at
which the oil failed.
Two separate tests
were performed for SAE 40 and SAE 50 oils, and results indicate
that 58.3 percent of the SAE 40 oils and 75 percent of the
SAE 50 oils passed stage 13. Although Mobil 1 MX4T, Motul
300V Sport and Torco T-4SR tested among the top SAE 40 oils
in the Four Ball Wear Test, they tested among the lowest in
the FZG Gear Wear Test. In addition, Motul 300V Competition
and Torco T-4SR tested among the top SAE 50 oils in the Four
Ball Wear Test, but also tested among the lowest in the FZG
Gear Wear Test.

Overview
As with any vehicle equipped with an internal combustion engine,
proper lubrication is essential to insure performance and
longevity. It is important to point out that not all internal
combustion engines are similarly designed or exposed to the
same types of operation. These variations in design and operation
place different demands on engine oils. Specifically, the
demands placed on motorcycle engine oils are more severe than
those placed on automotive engine oils. Therefore, the performance
requirements of motorcycle oils are more demanding as well.
Though the degree may be debatable,
few will disagree that a difference exists between automotive
and motorcycle applications. In which area these differences
are and to what degree they alter lubrication requirements
are not clear to most motorcycle operators. By comparing some
basic equipment information, one can better understand the
differences that exist.
There are six primary differences
between motorcycle and automotive engine applications:
Operational Speed -
Motorcycles tend to operate at engine speeds significantly
higher than automobiles. This places additional stress on
engine components, increasing the need for wear protection.
It also subjects lubricating oils to higher loading and shear
forces. Elevated operating RPMs also promote foaming, which
can reduce an oil's load-carrying ability and accelerated
oxidation.
Compression Ratio -
Motorcycles tend to operate with higher engine compression
ratios than automobiles. Higher compression ratios place additional
stress on engine components and increase engine operating
temperatures. Higher demands are placed on the oil to reduce
wear. Elevated operating temperatures also promote thermal
degradation of the oil, reducing its life expectancy and increasing
the formation of internal engine deposits.
Horsepower/Displacement
Density - Motorcycle engines produce nearly twice
the horsepower per cubic inch of displacement of automobile
engines. This exposes the lubricating oil to higher temperatures
and stress.
Variable Engine Cooling
- In general, automotive applications usa a sophisticated
water-cooling system to control engine operating temperatures.
Similar systems can be found in motorcycle applications, but
other designs also exist. Many motorcycles are air-cooled
or use a combination air/oil design. Though effective, they
result in greater fluctuations in operating temperatures,
particularly when motorcycle are operated in stop-and-go traffic.
Elevated operating temperature promotes oxidation and causes
oils to thin, reducing their load carrying ability.
Multiple Lubrication
Functionality - In automotive applications, engine
oils are required to lubricate only the engine. Other automotive
assemblies, such as transmissions, have seperate fluid reservoirs
that contain a lubricant designed specifically for that component.
The requirements of that fluid differ significantly from those
of automotive engine oil. Many motorcycles have a common sump
supplying oil to both the engine and transmission. In such
cases, the oil is required to meet the needs of both the engine
and transmission gears. Many motorcycles also incorporate
a frictional clutch within the transmission that uses the
same oil.
Inactivity -
Motorcycles are typically used less frequently than automobiles.
Whereas automobiles are used on a daily basis, motorcycle
use is usually periodic and in many cases seasonal. These
extended periods of inactivity place additional stress on
motorcycle oils. In these circumstances, rust and acid corrosion
protection are of critical concern.
It is apparent that motorcycle
applications place a different set of requirements on lubricating
oils. Motorcycle oils, therefore, must be formulated to address
this unique set of high stress conditions.

Consistent Clutch Feel
- Clutch slippage or inconsistent clutch feel can
prevent dirt bike riders from riding as fast or effectively
as they like. To keep the engine within the power band, riders
often modulate the clutch, increasing the opportunity for
clutch slippage if low-quality lubricants are used.
AMSOIL
Synthetic Dirt Bike Oil's superior friction-durability
properties help minimize clutch slippage, fade and chatter,
giving riders consistent clutch feel during takeoffs or when
maneuvering around obstacles on the trail. In an extreme simulated-start
test, AMSOIL Synthetic Dirt Bike Oil continued to deliver
consistent clutch feel following 32 simulated race starts,
while a leading original equipment manufacturer (OEM)-branded
oil demonstrated inconsistent clutch-lever action and poor
clutch feel after 16 starts. The clutch plates lubricated
with AMSOIL Synthetic Dirt Bike Oil remained clean and in
good overall condition, while the plates using the OEM oil
revealed discoloration and wear. AMSOIL Synthetic Dirt Bike
Oil's superior performance helps instill in riders the confidence
that their bikes will perform consistently in all types of
riding conditions.
Racing is Research -
AMSOIL corporately sponsored supercross and motocross racers
identified consistent clutch feel as a key performance attribute.
At the time, there was no dirt-bike-specific oil on the market
that provided the level of clutch consistency professional
and amateur riders demand. Consistent clutch feel is critical
to motocross riders during starts to keep the bike from lurching
forward prior to the gate dropping. Trail riders, meanwhile,
need consistent clutch feel to confidently navigate obstacles
without having to shift gears and lose momentum.
In-Depth Product Development
- The process to develop Synthetic Dirt Bike Oil
relied on a combination of lab and track testing. Clutch feel
is inherently subjective, which creates challenges in designing
a lubricant that delivers consistent clutch feel. To overcome
that challenge, AMSOIL designed The Extreme Simulated-Start
Test on Dirt Bikes. The test allows AMSOIL engineers to apply
accelerated stress to a dirt bike's clutch in order to monitor
clutch feel produced by a candidate lubricant.
The test uses a 2014 Honda CRF450R
attached to a dyno. While in second gear, the test administrator
holds the clutch at the point just prior to engagement, similar
to the way a rider would hold the bike in the gates during
a race start. The clutch is then released and the bike is
run to fourth gear, simulating the time from the drop of the
gate to the first corner in a race. The rear wheel is not
allowed to slip during the test, placing additional stress
on the clutch. Test administrators look for consistent lever
action and feel as they wait to let out the clutch and as
they shift the bike through the gears.
AMSOIL
Synthetic Dirt Bike Oil was also subjected to extensive
on-track testing in the bikes of GEICO/AMSOIL/Honda Factory
Connection and other professional riders. A combination of
rider feedback and lab testing resulted in the final formulation
of Synthetic Dirt Bike Oil. Its performance in lab and track
testing dispels the myth that synthetics are "too slippery"
and make clutches slip. Results also demonstrate that AMSOIL
Synthetic Dirt Bike Oil delivers consistent clutch performance
while helping extend clutch life. (Buy

NOACK Volatility Test
is a Critical Measurement of Motor Oil Quality
AMSOIL was
the first motor oil company in North America to use
the NOACK volatility test to measure motor oil quality
and performance. Although competing motor oil companies
initially paid no attention to NOACK results, the test
has since become a critical measurement tool throughout
the industry.
Modern engine
designs generate more heat than ever, accentuating the
importance of the NOACK volatility test for determining
an oil's ability to provide an adequate level of protection
and performance. More horsepower, turbo chargers and
aerodynamic styling have created extremely hot environments
that receive less cooling from outside air, and high
heat leads to oil oxidation, deposits and thickening
in conventional oils.
Top quality
for the current API SM motor oils specification, gasoline
motor oils cannot experience a weight loss of more than
15 percent in the NOACK test. AMSOIL Synthetic Motor
Oils were exceeding modern requirements over 20 years
ago, while many current motor oils still have a hard
time meeting this minimal requirement, increasing wear,
fuel consumption and emissions.
As seen in
the graph, AMSOIL Synthetic Motor Oil easily passes
the NOACK Test and falls well below the the maximum
15 percent volatilization (burn off) rate dictated by
the API SM motor oil specification, while the Royal
Purple volatilization (burn off) rate is over 11 percent
and the Lucas Oil FAILS the
test with a volatilization (burn off) rate of over 40
percent. (read

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.
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.
