Mobil 1 High Efficiency Oil Filter

[george nimmer]

Doug,

I think the VAG specified Mann or Mahle oil filters are probably the best
filter for our Audi's.  I've had other "store" brand oil filters collapse
internally (and you probably won't notice unless you have an oil pressure
gauge).  Every VW/Audi/Porsche mechanic I've spoken to has recommended the
same thing.  I believe the Mann and Mahle oil filters have a more rigid
internal construction to deal with the higher oil pressures of VAG (and
especially Porsche) engines.  Also, they have internal pressure valves which
allow the oil to bypass the filter element when it's still cold and viscus.
Other filters which don't have these valves will not provide as much oil to
engine until the oil gets hotter.  Another consideration is the material
seperating the filtered oil from the unfiltered oil inside the canister.  Take
the popular Orange colored filter  that can be found at many parts stores.
These could have the best filtering element in the world - but you wouldn't
know it because the material that seperates filtered oil from unfiltered oil
is a thin piece of cardboard.  Thats right, cardboard - which tends to
disintegrate when hot oil is flowing along side it at a high pressure.  That
being said, my only experience with a Mobil 1 oil filter was on my Porsche 911
SC engine.  The filter collapsed internally in less than 600 miles.  I've
never had that problem with the Mann and Mahle filters although the 3.0
Porsche 911 engine also relies on oil for cooling, and probably has a higher
pressure system than most older Audi's.

Just my 2 cents.
