1) No problem if bypass opens, IF IF IF IF, it is a CLEAN SIDE BYPASS!!!!! IF it is a dome side/dirty side, then it flushes the dirty side of the filter media into your engine!!!!!!! What could be worse. Next time you pick up an
oil filter look straight down if you see a button it is dirty side. If you see a spring just below the threads where it mounts it is a clean side.
2) Bypass would usually open when engine is cold and you are pumping 500 cst
oil and your
oil pump rv is lifting. 10W30 at 100c is only 12 Cst!!!! Understand 10w oil is thicker at 70F then 30W oil is at 212F!!!! Even though you are led to beleive 10W30 is only 10W when cold is fine, 10W at 50F is like syrup. 30W at 212 F is like rubbing alchol.
3)If you have a high volume oil pump theoretically we are pumping more oil so the pressure drop would be greater. If it exceeds the bypass setting it will bypass.
4) If your filter plugs off it will bypass. I saw one article that it would only take 14 grams to plug off a filter. This might happen in an older engine if you switched from dianasour to
synthetic and the
synthetic started cleaning it.

Can the bypass "open" due to excessive pressure, as in an extremely high pressure oil pump.....or does the bypass "open" only when the filter media will not pass adequate oil?
Sorta confused here....but find this thread incredibly interesting!
