I want to make it clear, I have NOT recommended the use of a non-bypassing oil filter. I am in agreement with the engineers who designed the Cleveland oil system, that dirty oil is better than no oil.
The standard oil filters with the built in bypass system filter 100% of the oil until the pressure drop across the filter exceeds 8 to 10 psi.
According to what I read on the Pure Power web site, their filter does have a relief (bypass) system. Is this right Ron?
The only specific oil filter recommendation I make is for those running the high pressure relief spring in their oil pump. For those individuals I recommend the Fram HP1 oil filter, the can of this filter has a 500 psi burst rating.
