[Vwdiesel] Oil Filters ---( Hot dam NOT a FRAM ? )

[Tom Krummell]

If you haven't reviewed the German oil filter study, it's worth 
reading.  VW OEM filters are manufactured by Champion Labs, as are Lee, 
Mobil 1, STP, Deutsch, and Bosch.  The Mahle filters may be made by the 
German affiliate of Champion Labs, as they are very similar internally.  
The study is quite interesting.

The author also compares the guts of filters specified for a 
large-engine Ford with similar results.

Since 3 of our 4 vehicles are A4 TDIs with the cartridge filter, I'm 
using Mann filters bought in bulk on eBay for around $5 each, or about 
$58 for a dozen.  The lone 2000 2.0 gas job gets Bosch or STP filters.  
STP cartridge filters for the TDIs are made in Korea or Thailand.  One 
time, and only one time, I had to get a Fram cartridge which was also 
made in Thailand.  Purolater cartridges in the past were Mann or 
Hengst.  The Mann filter has a unique design that keeps much of the oil 
from draining back into the engine when the engine is shut off.  If you 
peer down inside the cartridge you'll find a molded plastic cylinder 
that extends from the bottom about halfway to the top of the filter, and 
which prevents drainback of about half the oil contained within the 
filter enclosure.  None of the others, including VW OEM and Hengst, have 
this feature.
