I was wondering if anyone else out there has done any research on oil
and oil filters.
My filter studies over the last two days have directed me to this
document:
SAE Document
Document Number: J1858
Date Published: June, 1988
Title: Full Flow Lubricating Oil Filters
Multipass Method for evaluating
filtration Performance
Issuing Committee:
Filter Test Methods Standards Committee
Scope:
This standard establishes a multipass
filtration performance test with
continuous contaminant injection for
lubricating oil filter elements. It also
includes a procedure for determining the
contaminant capacity, particulate
removal characteristics, and pressure loss.
It also includes a test currently
applicable to lubricating oil filter
elements which exhibit a 10 um filtration
ratio of less than 75 and a rated flow
between 4 and 600 L/min. This
standard provides a test procedure which
yields reproducible test data for
evaluating the filtration performance of a
lubricating oil filter element.
I also see Mobil 1 point towards document j806.
Purolator points towards j1858 for multiple pass filtration
Are these the same tests at different dates?
Here are the filters results:
Mobil 1: Single pass efficiency (SAE J806) of 98% vs. an 85% average
for conventional filters. * Multiple pass efficiency (SAE J806) of 95%
vs. an 80% average for conventional filters.
PureOne: Single Pass Test efficiency for the PureONE filter is 99.7%.
PureONE captures 96% of all contaminants as measured by the
Society of Automotive Engineers' (SAE) #J806
Multiple Pass Test. *
Hey look I think I may have answered my own question. Both reference
j806. Never noticed that before!
Anyone have comments or more information on filters or oils? How much
does a Mobil1 filter cost. The PureOne filter was $5.99 at PepBoys.
