Fumoto Oil Drain Plug

[Peter Schulz]

Bernie:

Gary Martin's question was : "Why would a car manufacturer recommend these 
specs??:
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 
particles...

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.

;-)
