Oil pressure and oil flow are COMPLETELY independent. Consider if you had a
clogged passage - your oil pressure would be high, yet you'd have no oil
flow.

Smaller filters flow less oil than larger ones in general. Also, those that
are crammed full of filter media (several "premium" models) are more
restictive.

If you turn lots of RPM or have a performance-mdified engine and/or have a
high-volume oil pump, you should make sure you're not restricting oil flow
more than necessary with your oil filter. Unfortunately this data is hard
to find.

i dont think they are, if you have good oil pressure , then you have
enough flow .
