Keep in mind that aome companies switch the oem manufacturer or their filters without notice. A good amount of these brands don't make their own, but instead sign a contract with other manufacturers, like ACDelco and maybe STP. That means, they could switch from a good oem to bad oem (like fram at anytime). I've done some research, google "good oil filter and there should be lots of info, as well as look up the subject on Bob is the Oil Guy (I swear I'm not here to advertise that site, its just a wealth of knowledge about car maintenence),
