Dont forget about cold oil.

Also lets say that when your engine is at 90psi on the highway at 3300rpm and youre running a cheap oil filter, and at 90psi the filter presents around a 10psi restriction, you wont be filtering.

Guess what, I made that up, but Subaru didnt just make up their oem filter's bypass setting, so its probably a good idea to follow it.
