Gary Martin's question was : "Why would a car manufacturer recommend these
and my reply was " because they (the manufacturer/dealer) wants you to come
back soon and buy another (sic) car. "
And just to be clear, although you recommend the orange filter, not all of
the orange filters that fit the audi engines have the anti-drain back
valve, and furthermore...have consistently tested worse for capturing small
So going with your line of thinking, by using a new black filter that I buy
at less than $5, I have the same ability to capture particles with the new
filter that you have at 15k ( when your orange filter has accumulated
sufficient debris to "improve" its filtering capacity.) - too bad about
those first 15kmiles, when those small particles weren't captured.
