Field samples taken from user
vehicles demonstrate the
effectiveness of the Dei-Max® renewable filter in removing
solid particlulates from engine
oil during normal operation.
Dei-Max® renewable oil filters have been tested
both in the laboratory and in the line of duty by
several of the best police agencies in the country.
Automotive manufacturers do not advertise oil filter
performance standards. Filter manufacturers are
encouraged to adhere to the Society of Automotive
Engineers (SAE) OIL FILTER TEST PROCEDURE
HS-806 and a more recent J1858 version.
The purpose of SAE FILTER TEST PROCEDURE
code is to provide a means for evaluating the
performance characteristics of full-flow oil filters
on laboratory bench equipment.
Since the lube oil filter becomes an integral part of
the engine lubrication system, it’s actual performance
is subject to variations in operating conditions such as oil flow, temperature fluctuations, environment, and/or
vibrations that are difficult to duplicate in a laboratory.
SAE FILTER TEST PROCEDURE does not place
limitations on performance requirements and/or
tolerances, as these are considered the responsibility
of the user and manufacturer.
