From time to time I get people asking why Fram Oil Filters are not
recommended.
Saying this you have to be careful buying some other brands because they are
made by Fram.
Here is the web site of an oil filter test this information is based on.
Under normal
operating conditions Fram filters will perform adequately however in my
opinion there
are better choices out there with some being less costly. Check it out for
