Efficiency rating Motorcraft FL500S

Anyone know the efficiency rating for a Motorcraft FL500S oil filter? I searched the site and can't find anything on it. It isn't listed on the Motorcraft site either (that I can find). Thanks.

According the the AMSOIL study, the FL820S is 93.7%. If the FL500s uses the same media, I would expect the same numbers.

This, probably about 93% and that's as close as you're gonna find.
