CAT (caterpillar) oil filter

[_JB_]

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.

Yeah who knows what will happen from bankruptcy, https://bobistheoilguy.com/ is still the main source for all things oil related. I *think* Fram canceled the Titanium line (Advanced Auto exclusive) and Synthetic Endurance is a Walmart exclusive, but has been pulled from some stores. I can still order Synthetic Endurance through Walmart.com though.

There's a new version of Viper filters 5037836AC released in the past few months. I'm not sure if they've changed anything on the inside of filters. 5037836AB can still be found lots of places.

I just got two 836AB filters from Amazon today. They updated something if it’s now AC. I’m always seeing on FB about how others can’t get the 836AB even from dealers it’s on BO. Some are die hard and have to have the 836 or it’s the end of the world lol. Mobil 1 makes a great filter, and oil. Ams oil is good, very expensive. Used to used 0W50 signature series in my ex wife’s GT500. Expensive oil change, twice a year. I’ve always been more of a Valvoline guy. But I do run Shell rotella 15w40 diesel oil in all my small engines and motorcycles. This isn’t the first time bobistheoilguy has popped up lol. Very informative site for sure.

Oil and Filters is always a popular topic. I'm glad to see people jumping in with their own experiences.
That makes it seem like an active forum again.
