frams are the worst oil filter you can buy (notice I didn't even capatalize the name). There is no reverse flow check valve so if the filter is mounted horizontally, the oil drains right back into the pan. They also have the smallest filter surface area of any filter on the market.

A general rule of thumb is 10 psi for every 1,000 rpm is considered sufficient.
I personally would never like to see mine go that low though.
And FWIW, I always use Motorcraft oil filters too.
