Re: [Fwd: Re: 20v Oil Filter?]

FWIW, the Fram catalog says the PH2870A (VW/Audi fitment) filter DOES have
an anti-drainback valve.  Fram filters have a nasty habit of leaving the
O-ring gasket stuck to the adapter--if you don't catch it when you change
filters, you get a double gasket with the new filter and 2 quarts/L of oil
on the garage floor.  BTDT.  

What Audi *should* have done was put an anti-drainback valve in the oil
filter adapter (spin-on attachment block)--would make this all moot.  i
guess that'd be too sensible, wouldn't it   ;^)
