Re: Mobile 1 Extended Performance
Frank,
Most have anti-drain back these days, but some valve designs are more
effective than others:
http://minimopar.knizefamily.net/oilfilterstudy.html
Interestingly, Canadian Tire Motomaster/Formula One filters are all
rebranded Frams. Same is true of Quaker State/Pennzoil. If you're buying
filters at Canadian Tire, get K&N. Elsewhere, try Carquest Premium (aka
NAPA Gold).
Even some Mopar filters are Frams in disguise:

Re: Mobile 1 Extended Performance
Hi Frank,
The check valve is what you see in the radius holes, like the oil
is pump through the rubber looking flapper valve to the out side of the
filter element to enter to the center part that's screwed on the pipe
connected to the engine's oil galleys. Here's probably different in the
qualities of the bypass valves attached to the other end of the
screw-on, that would be very important in an all out hot rod. I can just
barley recognize those valves in this picture:

Re: Mobile 1 Extended Performance
Yep, presence of the 'anti-drain back' valve depends on the application.
Many are still produced without the valve. I don't think though that you
can find any non-valve filters listed for the 4.0L.
