AMSOIL
Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional, synthetic and synthetic
blend 10W-30 motor oils were subjected to a series of motor oil tests
by an independent laboratory using ASTM methods.
 The
competing oils tested included:
- AMSOIL ATM
- Mobil 1 Extended Performance
- Quaker State Advanced Full Synthetic
- Pennzoil Platinum
- Trop Artic
- Motorcraft
- Castrol GTX
- Chevron Supreme
- Havoline
- Formula Shell
- Pennzoil
Seven tests were run on the motor oils:
- Thin Film Oxygen Uptake (ASTM D4742) measures the oxidation stability of
engine oils.
- High Temperature/High Shear (ASTM D4683) measures a lubricant's viscosity
under severe operating conditions.
- NOACK Volatility (ASTM D5800) measures the evaporation loss of oils in high
temperature service.
- Pour Point (ASTM D97) indicates the lowest temperature at which a fluid will
flow.
- Total Base Number (ASTM D2896) is the measurement of a lubricant's
reserve alkalinity for combating acids.
- Cold Cranking Simulator (ASTM D5293) indicates the degree to which a lubricant
can impact cold weather starting.
- Four-Ball Wear (ASTM D4172) measures wear preventive characteristics
of lubricating fluid
The impressive test results show AMSOIL
Synthetic 10W-30 Motor Oil outperformed the competitors in nearly
every test.

| AMSOIL 0-30W Premium
Synthetic "Signature Series" Motor Oil (35,000 Miles) |
Recently AMSOIL introduced
the longest "drain interval" synthetic motor oil on the
market today. Those claims were made after extensive independent
and
"in house" laboratory testing.
AMSOIL
0W-30 (SSO) 100% Synthetic Motor Oil used with AMSOIL "Ea" Oil
filters can extend engine oil drain intervals to 35,000 miles for
many vehicles. |
| Compare Motorcycle
Oils |
| Motorcycle engines typically
run at higher RPMs and compression ratios than automobiles. Motorcycle
engine oils also have to perform throughout a wider variance of operating
temperatures. 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. |

 The testing used to evaluate
the lubricants was done in accordance with American Society for Testing
and Materials (ASTM)
procedures. Test methodology has been indicated for all data points,
allowing for duplication and verification by any analytical
laboratory capable of conducting the ASTM tests.

The motorcycle oils tested were evaluated for:
- An oil's ability to meet the required viscosity grade of an application.
- An oil's ability to maintain a constant viscosity when exposed to changes
in temperature.
- An oil's ability to retain its viscosity during use.
- An oil's ability to resist shearing forces and maintain its viscosity
at elevated temperatures.
- An oil's zinc content.
- An oil's ability to minimize general wear.
- An oil's ability to minimize gear wear.
- An oil's ability to minimize deterioration when exposed to elevated
temperatures.
- An oil's ability to resist volatilization when exposed to elevated
temperatures.
- An oil's ability to maintain engine cleanliness and control acid corrosion.
- An oil's ability to resist foaming.
- An oil's ability to control rust corrosion.
The purpose of this extensive testing on motorcycle oils is to provide information regarding motorcycle applications, their lubrication needs and typical
lubricants available to the end user. It is intended to assist the end user in making an educated decision as to the lubricant
most suitable for his or her motorcycle application.

 In
September 2007, the AMSOIL Drivetrain Division published comprehensive
test data after
testing multiple competitive Gear Lubricants on the
market today.
The requirements for automotive gear lubrication have substantially
changed, while vehicle owner awareness lags behind.
The differentials that house the gears are out of sight, out of mind,
often neglected. But differentials are just
as important to the operation of a vehicle as the engine.
Gear lubrication needs to be taken more seriously than before.
Modern
vehicle aerodynamic design is decreasing
air flow over differentials, increasing operating temperatures.
Engine performance and horsepower is on the rise along with towing
and cargo capacities. We are working our vehicles harder than ever,
causing what might seem like everyday operation to conceal extreme
service
conditions.
2007 turbo diesel pickup trucks, V-10 gasoline pickups and sport
utility vehicles (SUVs), and high-horsepower V-8 trucks
have more towing and payload capacities than in previous years, yet
their differentials have not changed much. |
| Automotive Gear Lubricant
Testing Methods |
| The testing by which
the gear lubes were evaluated was done in accordance with American
Society for Testing and
Materials (ASTM) procedures, Society of Automotive Engineers (SAE) J306 requirements
and Federal Test Method
Standards. Other than the oxidation filter patch procedure, performance testing
was conducted by an independent laboratory.
Physical-property testing (viscosity, viscosity index, pour point and foaming
after oxidation) was conducted in-house. |

| Gear Lube Performance
Testing |
The performance characteristics
evaluated include each gear lube's ability to:
- Meet the required viscosity grade of an application
- Maintain viscosity when subjected to temperature changes
- Retain viscosity during use
- Function in cold temperatures
- Resist high temperatures and oxidation
- Protect under extreme pressures
- Protect against wear
- Resist foaming
- Prevent copper corrosion
The purpose of these Gear Lube Tests and comparisons is to inform end users about
the
increasingly severe conditions under which differentials operate and to provide
data reflecting
the
quality and cost differences of popular synthetic and petroleum gear lubes. With
this
information, consumers are better prepared to make informed decisions when purchasing
gear lubricants.
