If you go to youtube, and search for oil filter comparisons there are a couple videos of a guy who cuts most oil filters you find at walmart open to examine where your money really goes when you choose one.
I forget all the details, but i remember Fram being one of the very worst in internal quality right along side that "super tech" cheap brand. As in the internal media was held solely together with
glue, and
cardboard, on an OIL FILTER
.
And of course the best was Purolator(sp?), and Motorcraft which were almost identical in design, the internal media was held together properly with stamped steel and a steel end cap with a metal sping bypass valve if the filter becomes too clogged as to not restrict oil flow.
Ill never use any oil filter beside Purolator, or Motorcraft. Unfortunately I can only use Fram for my motorcycles oil filter, seeing how thats the only company any place seems to carry....might need to start ordering those online.
