[DML] Purflux Vs. Bosch

["pool05743" <epool2005@xxxxxxxxxxx>]

I know this topic has been around a long time but I can't seem to 
find a definitive answer and reason.  What filter is the best and 
why?  I have heard the purflux does not have an anti drain back valve 
or a bypass valve.  I have also heard that it does have these but 
that they are weaker than the bosch.  I would just like to know 
(price aside) what filter is better and what makes that filter better?

Another question, I recently bought two Peugeot oil filters from 
France.  The numbers on the filters are 1109.45 and the numbers on 
the box are crossed out and now read 1109.78.  When I look at the 
purflux web site I see that both those numbers cross ref. to the 
purflux LS410C.  The filter is a dark blue with yellow print.  They 
do have the chevron style filter element.  Can anyone tell me more 
about these filters?  Are they of any historical significance?  Would 
they be allowed in concours events?  

Last question, do oil filters go bad?  Is there any reason to be 
concerned with an oil filter that has sat unused on the shelf for a 
long time?  Will the rubber seal go bad?  Will the filter element 
become brittle and possibly separate thus causing damage to the 
engine?  

I appreciate any information on these topics.  I am sorry to bring it 
up again.  I am sure everyone is tired of talking about it.
