From my research, Fram is owned by PGI NorthStar (parent company premium guard) based out of Memphis. They acquired Fram from bankruptcy along with 12 other aftermarket manufacturers including autolite, trico and several others. Amsoil outsources to Donaldson and champion laboratories…. Donaldson is also sourced to CAT in partnership. Is Amsoil a rebranded CAT filter? Hmmm. I think I’m gonna start cutting open some of my own filters and see how much metal they collect compared to some of the smaller CAT filters I pull off various equipment. Compare the internals. Seems how I’m changing the oil on my truck today, I’ll start with the K&N first. I do know Fram had glue issues with the cardboard inside the filter coming apart and starving engines of oil. I know K&N has the same issue as well, but from what I have read it’s been taken care of. I do not know when Fram was sold so I don’t know if the cardboard/adhesive issue has been resolved in sure it probably has as this was years ago as well may possibly be why they went bankrupt…. Again I have no idea. Further research might tell. If any of the info. I find is wrong please politely enlighten me lol. I hate receiving wrong info, and I do NOT want to spread false info around like a Jackass.
