no oil pressure

Well, I read the Fram issues with interest and cannot gainsay people's direct experiences. But I can report that I have used Fram for 40 years for most uses in gas and diesek engines alike, and all the time in racing applications where we are running the engines for 100+ miles in a day hard out plue a few hundred miles of cruising in between. This includes turbo apps and covers about 70 hard, longs 200-400 total mile events.

The one thing I am curious about is if these failed Frams have been used with high pressure oil pumps. These pumps will increase the flow as well as the pressure, and the net pressure drop across the filter element will go up considerably with both of those factors combined. So perhaps that is the issue, and I can see the hihger total pressure drop blowing out some elements.

I have always run my race engines with no more than 75 psi max, to avoid any issues with pumping oil excess to the heads or past turbo seals, or any aeration of the oil, and concentrate on a good tight pump that will deliver flow, as that seems to be the key in my racing more than pressure. BTW, my racing apps are all performance rallies, not drag racing. In those events, one often has extended times of many 10 of seconds or even several minutes with rpms constantly between 3000-8000 at 75-100% load, so excess pumping issues may be more of a problem there than in the short bursts of drag racing. Thus my de-emphasis on high pressure and more emphasis on constant flow at moderate pressures.
