the Most Severe Operating Conditions -
Tests Prove AMSOIL Greases
Offer Superior Protection!
synthetic greases were recently included in
a series of tests designed to determine how
different greases perform under normal and
sever operating conditions. The tests were
conducted by and independent grease company
and included four competitors' greases. Permatex
Super Lube, Mobil 1 Grease, Lubriplate 1200-2
and Mystic SX-6 were tested along with AMSOIL
Series 2000 Racing Grease, Synthetic Multi-Purpose
Grease and Synthetic Heavy-Duty Grease.
The tests are
designed to measure the performances under
a wide range of operating conditions. The
operating environments produced during testing
simulate the conditions found in contemporary
industrial and automotive equipment. As manufacturers
design equipment that operates under greater
stress, lubricants like greases must demonstrate
the ability to resist failure.
of industrial and automotive equipment continue
to test the limits of current lubricants by
designing machines which operate at higher
loads, higher speeds and higher temperatures.
These changes in design can reduce the strength
of moving parts in equipment and increase
the need for high quality lubrication. Greases
must stay in the place they are needed and
provide extra lubricant film thickness between
moving parts. This extra film thickness reduces
wear and friction and keeps equipment operating
at peak performance.
conducted using an SRV testing machine and
followed Test Method ASTM D 5707. The testing
involves the application of pressure on a
small steel ball which is being spun on a
steel disk. As the pressure and temperature
are increased the ball develops wear scars
similar to the scars developed on a four-ball
wear test for oils. The protection provided
by each grease can be measured by the number
and size of the scars left on the ball. Two
separate testing protocols were used. Passing
or failing was determined by wear scar size
and a maximum acceptable friction limit.
The first test
involved less pressure, slower speeds, less
heat and was conducted for a shorter amount
of time. This test was intended to simulate
normal operating conditions for most machinery.
The fully synthetic competitors, Permatex
Super Lube and Mobil 1, were both on the brink
of failure by the end of the first test. Mystic
SX-6, Lubriplate 1200-2 and the three AMSOIL
greases all performed well.
series of tests simulated more severe operating
conditions. The graph below illustrates the
results of the second series of testing. This
test featured higher pressure, higher temperatures,
faster speeds and lasted for a longer time
period. Permatex Super Lube and Mobil 1 were
unable to maintain an acceptable level of
friction and failed the test. The semi-synthetic
Mystic SX-6 could not withstand the hotter,
faster and more heavily loaded conditions
and also failed the test. The Lubriplate grease,
which is a lithium complex mineral oil grease,
did maintain an acceptable co-efficient of
friction, although its ability to prevent
wear suffered. All three AMSOIL greases provided
a superior level of friction reduction and
it passed the severe series of tests, the
Lubriplate grease was unable to prevent wear
as well as the AMSOIL grease. During the second
series of tests, the Lubriplate grease developed
wear scars at 38,000 psi of friction. The
AMSOIL greases didn't develop wear scars until
much later at, 42,800 psi of friction. Additionally,
the tests indicated that the wear in the Lubriplate
grease began at the start of the second test.
This could mean wear in machinery would begin
as soon as conditions become sever.
performance of the AMSOIL greases was excellent.
They provided superior protection and friction
reduction under both normal and sever operating
conditions. The AMSOIL greases can be counted
on to remain in the places that they are needed
and to provide stable overall lubrication
in even the most severe service conditions.
A small scar under the conditions maintained
in these tests could mean a much larger problem
in any industrial or automotive application.
Bearing and component wear is one of the chief
causes of equipment failure. The costs associated
with repair and replacement of bearings and
machine components can be avoided by providing
machinery with the necessary lubrication to
avoid excessive friction. These tests prove
once again that AMSOIL greases are the best
way to protect and prolong the life of industrial
and automotive equipment.
