Testing Procedures
& Results
METX has subjected its products
to a number of tests (with no modification) performed by third party, world
renowned, industry accepted and respected laboratories. Those tests include, but are not limited to
the following:
(A)
METX
Engine Formula:
ASTM D testing of the product
through the use of the Block-on-Ring Tester and the Seta Shell Four Ball Test
machine (ASTM D-2509, D-4172 and D-2782), Pin & Vee Block (ASTM D-2670,
D-2625 and D-3233) demonstrates the ability of the product to perform as an
extreme pressure additive.
Each of these test machines incorporates a rotating steel surface applied against a fixed steel surface while submerged in a bath of the test lubricant. Pressure is noted as kilogram force (KGF) applied to the mating surface while the rotating surface is set for a fixed RPM (revolution per minutes).

Pressure is noted as kilogram force (KGF) applied to the mating surface while the rotating surface is set for a fixed RPM (revolution per minutes).
The positive results using METX
Engine Formula are as follows:
Numerous qualified engine tests
were completed including small engines, 2-cycle, steam turbines, jet turbines,
gasoline and the CRC L-38. These tests
have demonstrated the ability of METX Engine Formula to perform
universally. Further, these tests
demonstrate that METX Engine Formula provides a protective effect that remains
on the treated metal. Four cylinder
engines, after treatment with METX Engine Formula, have been stripped of valve covers, oil
pans, oil-pumps and filters, with only the molecular thin film of METX Engine
Formula, have successfully run without either oil or coolant, both on an engine
stand and while completely submerged in water.
These tests have been run repeatedly and recorded before professional
engineers. The engines have been
recorded to run in excess of 25 minutes while completely submerged under
water. The motors were later stripped
and the components reviewed and re-weighed with little sign of wear.

Test: 1
CRC L-38
Testing has been completed on a
CRC L-38 Engine Stand ASTM D-5119-90 (American Society for Testing and
Materials). This rigorous test was conducted
at prestigious Testing Centre in the US.
It is one of the largest
independent automotive testing organizations in the world, providing testing to
the automotive manufacturers and petrochemical industry since 1953. Their
customers are worldwide, and include Shell Oil, Exxon-Mobil Oil, Chevron,
Castrol, Pennzoil, Petro-Canada etc., along with automotive OEM’s, heavy-duty
engine OEM, OEM suppliers and fuel and lubricant companies. This firm was designated by the United States
Petroleum Task force to regulate and control of the quality and acceptance of
regulated additives.
This firm was contracted to test
the METX Engine Formula when combined with an off the shelf motor oil. The reference oil used in the test was rated
as a licensed API (American Petroleum Institute) spec motor oil, The test is a gruelling 40 hours of severe
running conditions plus 13 hours of run up and run down time. The engine is run under full load at an RPM
(revolutions per minute) of 3150 using an external oil heater to reach extreme
oil temperatures of 290 degrees Fahrenheit (143.3 degrees Celsius) with fuel to
run abnormally rich at 4.5 pounds per hour.
The test is designed to break the
down the oil, causing premature wear to the piston rod bearings, while have an
adverse effect on the viscosity of the engine oil. The reduced viscosity of the oil can create
excessive wear and increase the amount of sludge and varnish build-up.
The scoring is based on a
reference oil test on a particular machine. The reference oil must have passed
the test on one of the many test machines.
The maximum allowable bearing loss is 40 mg of copper for the piston rod
bearing. Sludge and varnish deposits are
scored best out of 10 points, with 10 being perfect.
The engine assigned for the METX Engine
Formula test was rated as the most difficult on which to obtain a passing
score. The reference oil recorded a
bearing weight loss of 27.7-mg. of copper.
The oil with the METX Engine
Formula recorded a bearing weight loss of only 9.0 mg. The engineer overseeing the test commented
that it was one of, if not the best, test he has seen in over 12 years of
service with Perkin Elmer. Further the results of viscosity, sludge and varnish
tests were nearly perfect. Out of a
total of 60 possible points, the test with METX Engine Formula scored 58.30 and
58.80 respectively in varnish and sludge.
(The results exceeded all expectations.)

Tests were conducted on the
various engine components at the completion of the test to evaluate any changes
the test oil with the added METX Engine Formula may have had on the
engine. ASTM and the ACC (American
Chemical Council) for the API (American Petroleum Industry) allow permitted
deviation before a failure is recorded.

is 40mm (1.57”).
This test is normally
performed at 800 RPM (329 FPM). For the
METX EF test, it was performed at 1725 RPM (699FPM), which is the maximum
speed. There was no cooling pump being
run for the METX EF test. The test oil
specimen flows at 50ml/min (.013209 GPM or 3.05127 Cu. In. / Min.). Standard Timken roller bearings were used
with outer race of ANSI 52100 steel.
Mating blocks may be white metal, bronze on steel C 0.9, MN 1.2, Cr 0.5,
W 0.5, V 0.1 (2510 AFNOR 90 MCW5 Case Hardened. To 58HRC). Load on different blocks: steel/steel = 1075
RPM, bronze/steel = 358 RPM, white metal/Steel = 179 RPM.
Test Routine:
The speed is first adjusted and
then the load is steadily increased to the maximum permitted within a period of
5 minutes. Each test was then run for ½
hour. Recordings were made for maximum
friction force and minimum friction force after run-in period. A stable curve
was recorded at the end of test and maximum temperature was also recorded.
After completion of over 80
tests, SEM (Scanning Electron Microscope) studies, for material reference and
wear track studies showed the following:

Engine Stand
Testing
A brand new NASCAR™ engine was
provided for testing on a dynamometer.
The engine was run in on Kendall Racing Oil™ and numerous pulls were
performed. METX EF was then added to the
Kendall Racing Oil ™ at a 10% ratio (20 parts oil to 2 parts METX EF). The test is posted as below.
Dynamometer Test on 358 Cu. In.
GM® Engine (5.8 Litre)
- The NASCAR™® Engine was set up
and run in to full operating temperature at speeds to 6900 RPM.
- After multiple runs with
Kendall Racing 20W50 Racing Oil ™, the maximum results were recorded in both
horsepower and torque.
- METX Engine Formula was then
added at a 10% ratio and the tests repeated with maximum results recorded.
Results:
- STPPwr-Chp Kendall® Maximum
Horsepower = 494
- STPPwr-Chp with 10% METX EF added to Kendall®, Horsepower = 508
- STPTrq-Clb-ft Kendall® Maximum
Torque = 399
- STPTrq-Clb-ft Kendall® plus 10% METX EF added, Torque = 411
Test: 9
Copper Corrosion
Test: ASTM D-130
The tests were carried out on
polished copper blanks that were submerged, for 3 hours at at100 degrees C, in
oil treated with 15% of METX Engine Formula and a number of its blended
by-products. The blanks were then withdrawn, washed in Stoddard’s solvent and
the colors of the blanks were compared with a standard chart. The results of the tests consistently
revealed 1-A, meaning “No Corrosion”.
Test: 10
Rheological
Evaluation:
Rheological evaluation was
performed on the METX Engine Formula when blended with various conventional
motor oils. The test is to examine the
effect that METX EF can have when blended with a host oil.
The samples oils tested with 10%
and 15% addition of METX EF displayed Newtonian behavior (the desired results)
at all temperatures tested. The treated
oils displayed a substantial improvement in minimizing thermal degradation with
the addition of METX EF. Using standard
regression techniques, the variations of oil viscosities with each temperature
was found to follow the Arrhenius model, AE/RT (n = Ae) (excellent result).
Further tests conducted on METX EF include, but are not
limited to:

Note: The 4-ball wear or weld
tester consists of 4 balls arranged in the form of an equilateral
tetrahedron. The three lower balls are
held immovable in a clamp (chuck) to form a cradle in which the fourth ball is
caused to rotate around a vertical axis under prescribed conditions of load, speed
and temperature. Ten ml of the lubricant
are placed with the ball pot and, after the test is completed, the wear scar is
measured, length and width, on each of the three balls. The spinning ball is not measured. Pressure exerted upon the balls is measured
in KgF. (Kilogram Force)

Note: With Leading Cleaner, Lubricant, there was a large amount of metal
deformation taken off the spinning ball in the chuck and deposited on the three
stationary or locked balls. According to
the ASTM D2782 test, with stationary balls, a scar size of 4 mm or greater is
considered a weld, or total failure.
