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 the prestigious
PerkinElmer Fluid Science Automotive Research Center/ Intertek Caleb Brett (formerly EG&G
Automotive Research) located at 5404 Bandera Road, San Antonio, Texas.
Perkin Elmer/Intertek Caleb Brett is one of the largest independent automotive testing
organizations in the world. PerkinElmer/Intertek Caleb Brett has been 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.
PerkinElmer/Intertek Caleb Brett was contracted to test the BestLine's Universal
Premium Full Synthetic Engine Treatment 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 grueling 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 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 buildup.
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 BestLine 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 BestLine's Universal Premium Full Synthetic Engine Treatment 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 PerkinElmer. Further, the
results of viscosity, sludge and varnish tests were nearly perfect. Out of a total of 60 possible
points, the test with BestLine's Universal Premium Full Synthetic Engine Treatment scored
58.30 and 58.80 respectively in varnish and sludge. (The results exceeded all expectations.)
