First, the claim that most oil filters trap debris by oil flowing 
across oil
filter paper, not thru it. "Most "throw away" filters flow oil at 7-9 
gpm and
is known in the industry as a "nominal extraction" filter. In a "throw 
away"
filter the oil DOES NOT go THROUGH the paper filter --it is designed to 
run the
oil BY the paper element. Small (NOMINAL) amounts of debris are then 
"snagged"
or settle in the valley of the pleats. In most paper filters the Bypass 
opens up
shortly after engine startup.

Is the above statement true?
