It is not card board and reality check what is the filter media made from? and yes some Fram Filters have fiber end caps as do other brands. Look at the picture the great people post in the oil filter section.This are fiber endcaps, not paper or cardboard.Originally Posted by viscousBut I saw a 3-year-old youtube video showing the cardboard. I was wondering if these endcaps tend to degrade while sitting in oil unused.Originally Posted by IgnatiusFirst of all Fram has not used any of the dread cardboard endcaps for about a decade, why people still believe that they do I don't know. Might as well believe that Saddam was getting ready to nuke America in 2003.
