Under all this is the undeniable fact Fram, a large respected company, advertises and even gives the holes a special name. You are spending a lot of time trying to prove someone is wrong , but it's a waste of time. because I am not the one advertising it. I offered some explanation in support of Fram, and so far I haven't read anything that proves Fram wrong. If they are wrong and making it all up that's a bad mark on Fram, not me. Not sure I would trust other things Fram claims. It's pretty funny actually, and what this is really all about, how the board controller makes sure his opinions are the ones the board follows. Disagree or question, and we all see what happens.
