Presently manufactured oil filters have top by-pass valves (under the cover) or bottom by-pass valves (built in the bottom of the filter cartridge). In filters with bottom by-pass valves, the oil must flow round the filtering cartridge and the can bottom at the time when the valve operates. The sudden oil flow may cause washing out gathered contaminants which may lead to excessed working engine elements wear. The effect may be even worse due to the fact that the valve opens more frequently when a lot of contaminants accumulate. When the engine starts, the by-pass valve in filter opens and contaminants are pushed into the engine. Top by-pass valve placed in the filter excludes effect of washing contaminants out since the oil flow does not flow round the filtering cartridge during the valve opening. Therefore the engine is better protected from contaminants which can't be taken out of the filter once it gets there.

Uljni filtri koji se danas proizvode imaju protočne ventile sa gornje strane (ispod omotača) ili donje protočne ventile (ugrađene u donjem delu uloška za filtriranje). Kod filtara sa donjim protočnim ventilima, ulje treba da protiče oko uloška filtra i oko dna lonca u trenutku kada se ventil uključi. Iznenadni protok ulja može izazvati spiranje sakupljenih nečistoća, što može dovesti do preteranog habanja pokretnih delova motora. Efekt bi mogao biti i teži jer se ventil češće otvara kada se nakupi mnogo kontaminirajućih agenasa. Kada se pokrene motor, protočni ventil fitra se otvara i nečistoće se potiskuju u motor. Gornji protočni ventil postavljen u filtru isključuje efekat ubacivanja nečistoća, jer ulje ne teče oko uloška filtra u vreme otvaranja ventila. Iz ovog razloga motor je bolje zaštićen od kontaminirajućih agenasa koji više ne mogu napustiti filtar kada jednom tamo stignu.
