I don't dislike any evaluation of any product providing it is backed up with
statistical evidence from a recognisable and respected organisation. Too
many of the reports I have seen on the 'net over the years seem to be
written by people with little experience of what they are researching and
even less convincing statistical evidence. I admit I didn't read all of the
report on this latest issue - so perhaps I may have missed something of
relevance?
In my own case, I am fortunate in having many friends within the UK motor
industry who are regularly involved in testing many aftermarket products and
brands against laid-down factory specs. While these tests are for modern
engines in contrast to the engines in our older vehicles - Fram, MAN,
Purolator and Unipart are claimed by experts to meet or exceed OE specs in
terms of life expectancy, flow rate, manufacturing accuracy and filtration
efficiency. It seems MAN is top of the list with Fram a close second. Both
these filters cost me about US$10 and conveniently (for me) fit a number of
current engines from Rover, Peugeot, Citroen and Daimler Benz. I also use an
additional by-pass filter on both Triumphs whose element is a similar size
to a toilet roll. This successfully traps sludge down to about 2 microns and
each element costs US$30. Needless to say, my oil is a dark yellow colour
when changed at 3000 miles.
