One other thing that hasn't been discussed yet is the fact that Fram and
other no-name filters have bigger holes in the filter material than the
Mahle/Mann filters.  This is supposed to allow for better flow and less
restriction, but it also creates a lower oil pressure condition in the engine
(that's why oil light flickers at idle after the engine warms up).

If I had a dollar for every person that has driven over here with a no-name
filter complaining of lifter tapping and oil light flickering...

All I have to do is look under the van and see that ugly orange or white
filter and I know what the problem is.

I have a bunch of the Mann filters here right now for $4.25 each if you buy 5
at a time or $5 each for singles.

Hope this helps,
Ken Wilford
