When I was in HS (which would have been about '84-'85) I had two Fram filters, one was an 'old' one (never used, still in its package), and a brand new one from the local auto parts store.

The weight difference between the two was VERY obvious. The 'old' one felt almost as if it were full of oil it was so much heavier than the new one. I didn't know at the time that Fram had been bought out.

I continued to use Fram off and on off for a few more years, then, I started noticing the differences with oil pressure between Fram and a good filter like WIX.

I've never had an engine 'blow up' because of a Fram (though the original engine to my wagon has a spun bearing and a Fram filter on it, coincidence?) but, I use only WIX now.
