There was considerable discussion here about which filter to use and it was noted the newer PF64 has a bypass setting which is specified by GM engineers for the engines used in the Camaro(22psi). Most other filters often have lower bypass levels or don’t specify their bypass rating. The idea is starts in cold weather conditions might cause the filter to bypass allowing unfiltered oil to circulate. Some people offered the rumor that using anything other than the spec’d filter will/might void your warranty. I don’t believe this is true and I know of nothing published by GM confirming this, although there was a TSB which details the concerns.
